Another option to consider is crop rotation where you plant resistant cultivars which provide additional benefits such as help reduce pest problems, reduce nutrient depletion while creating conditions necessary for a regime change within the ‘holistic’ scope of sustainable agriculture and organic farming.

What is Soil amendment?

Soil amendment is the practice of adding organic matter, nutrients, and beneficial microbes to soil in order to improve its quality and fertility. [Wikipedia]

What are DIY Natural Soil Amendments?

Definition and Explanation

Soil amendments refer to adding materials to the soil that can improve its quality. DIY natural soil amendments refer to using organic and inorganic substances that are easily available and can be made at home by anyone interested in improving their garden or farm’s productivity.

Natural soil amendments provide a wide range of benefits, such as enhancing soil structure, boosting beneficial microbial activity, increasing nutrient availability, and providing slow-release fertilization.

Organic Substances

Organic substances for natural soil amendments refer to using plant-based material such as leaves, manure, grass clippings, food scraps, coffee grounds or any other organic matter that is readily available in most households. The breakdown of these materials provides essential nutrients for the plants. In addition, they fortify the soil with nitrogen and other crucial minerals from bacteria decomposition speeding up the process of making organic fertilizer straightforward.

DIY natural fertilizer recipes require you to gather all your biodegradable wastes within a bucket or composting bin. Users stir gently twice or thrice per week. For composting purposes, it should break down naturally over three months when applied as an amendment content on your farm produce.

Examples of organic substances include:

  • Compost: This is decayed food waste mixed with other biodegradable wastes used for rejuvenating soils
  • Vermicompost: It refers to the use of earthworms often called red wigglers used in vermiculture whereby worm excrement improves soil drainage
  • Bone meal: They are a mixture obtained from grinding animal bones rich in phosphate and calcium.
  • Manure: Goat manures contain sodium which could boost growth while chicken droppings provide rich nitrogen levels required in gardening plants.
  • Wood chips: Helps create humus-rich which retains water to provide favorable living conditions for shrubs.
Inorganic Substances

Inorganic substances have numerous benefits since they act faster and are readily accessible at most agricultural stores. The soil PH levels, nutrient deficiencies, water management can be improved with the correct use of these substances.

Examples of inorganic substances:

  • Limestone: Reducing acidic properties by reducing acidity in your soil is achieved by blending limestone which provides calcium essential for growth.
  • Epsom salt: Contains magnesium sulfate which promotes plant growth rate and enhances chlorophyll found in plants
  • Potassium chloride: It promotes flower formation
  • Rock dust: Rock minerals and soils contain nutrients such as potassium, iron or manganese that boost plant development

  3. Slower release rate – With slower nitrogen delivery rates, plant uptake thereby wasting valuable resources incurred by gardeners seeking efficient higher productivity outcomes in shorter time frames.
  4. Lack of Prescribed formulas – unlike commercial varieties that come fully tested with precise mixtures ensuring consistency in nutritional gain standards attained by farmers using DIY fertilizer trial and error maybe part component process discouraging buyers who cannot sustain inconsistencies arising due to varied testing measures employed over homogenously processed commercial fertilizers.

Overall, the decision to go for commercial or DIY natural soil amendments depends on various factors such as crop sustainability plans desired output, input management, geographic location among others. Nonetheless, opting for DIY natural soil amendments come with the satisfaction of knowing that one is doing their part in promoting sustainable farming and environmental conservation practices.

Benefits of Using DIY Natural Soil Amendments

As a gardener or farmer, you must have heard about soil amendments. If you haven’t, they are materials that you add to the soil to improve its properties. These materials could be organic or inorganic and serve various purposes like improving nutrient content, enhancing soil structure, and supporting healthy soil life.

Of all the types of soil amendments available, natural ones are usually preferred because they offer more benefits than their synthetic counterparts.

Improved Nutrient Content

One primary benefit of using natural soil amendments is improved nutrient content. These materials help to make essential nutrients like nitrogen, phosphorus, and potassium readily available to plants. This is achieved through the decomposition of organic matter by microorganisms in the soil.

Nitrogen-rich Soil Amendments

Nitrogen is an essential element that plants need for growth and development. It’s responsible for processes like photosynthesis and protein synthesis in plants. Plants that lack nitrogen will grow slowly and produce small leaves.

Some common examples of nitrogen-rich natural amendments include:

  • Manure: Manure from animals like cows, horses, goats contains high amounts of nitrogen.
  • Compost: Compost made from decaying plant-based materials can also provide plants with nitrogen.
  • Blood meal: This is a dried blood product from slaughterhouses rich in nitrogen.
Phosphorus-rich Soil Amendments

Phosphorus is another vital nutrient that plants require for proper growth and development. It’s responsible for energy transfer within plant cells and plays an important role in root formation.

Some examples of phosphorus-rich natural amendments include:

  • Bone meal: Ground-up bones provide plants with both calcium and phosphorous.
  • Rock phosphate: A mineral mined from ancient deposits provides slow-release phosphorous to plants over time.
  • Fishbone meal: Dried fish bones contain high amounts of both calcium and phosphorous.
Potassium-rich Soil Amendments

Lastly, potassium is an essential nutrient that helps to boost a plant’s immunity against diseases and pests. It’s also responsible for regulating water uptake in plants.

Some examples of potassium-rich natural amendments include:

  • Kelp meal: This is made from dried seaweed and contains trace minerals as well as potassium.
  • Wood ashes: This byproduct of burning wood provides plants with both calcium and potassium.
  • Greensand: A mineral mined from ancient sea beds, greensand offers slow-release potassium to the soil.

Enhanced Soil Structure

Another benefit of using natural soil amendments is enhanced soil structure. These materials help to improve soil drainage and water retention capacity.

Soil Drainage Improvement

Soil drainage refers to the ability of water to move through the soil profile easily. In well-drained soils, excess water doesn’t accumulate at the surface, which can suffocate plant roots or cause diseases like root rot.

Some natural amendments that improve soil drainage include:

  • Sand: Adding sand to clay soils can help loosen them up and increase drainage.
  • Perlite: This light volcanic rock also increases drainage in compacted soils.
  • Pine bark fines: When added to soils, they maintain better air space between particles which reduces compaction leading to improved drainage.
Water Retention Capacity Enhancement

Water retention capacity refers to how much moisture a given amount of soil can hold onto. Soils with good water retention capabilities don’t need frequent watering compared with their poorly retaining counterparts.

Some natural amendments that enhance water retention capacity include:

  • Compost: Well-made compost containing some organic matter can hold three times its weight in moisture
  • Coconut coir: Coconut coir fibers hold ten times their weight in moisture making it perfect for raised bed gardens.
  • Peat moss -Sphagnum peat moss has an excellent ability to retain moisture; however, sustainable management practices must be considered to ensure it can continue being a viable resource.

Healthier Soil Life

Finally, natural soil amendments help to support healthy soil life. These materials provide food for beneficial microorganisms required to grow strong plants while offering protection against soil-borne diseases and pests.

Supporting the Growth of Beneficial Microorganisms

Healthy soil is alive with microorganisms like bacteria, fungi, protozoa, and nematodes that work together to improve plant growth, protect against pests and diseases as well as many other benefits.

Some examples of natural amendments that support the growth of these organisms include:

  • Vermicompost: this is compost that has been created using special earthworms Wigglers which eat through organic waste creating compost in their castings rich in beneficial microbes.
  • Alfalfa meal: When added to the soil, alfalfa will break down quickly providing food for beneficial bacteria such as Pseudomonas or Bacillus.
  • Molasses: When used as a foliar spray or added during waterings molasses feeds not only plants but also provides food sources for microbes.
Protection Against Soil-borne Pests and Diseases

Soil-borne diseases and pests are quite common in garden spaces that have been planted regularly without replenishing nutrients. They cause poor plant performance leading to stunted growth and reduced productivity.

Some natural amendments that offer protection against these threats include:

  • Garlic: Adding crushed garlic cloves or juice protects plants from root maggots while warding off insects like aphids.
  • Neem Seed Meal: Made by grinding neem seed kernels; this amendment controls over 200 insects as well as shore flies when applied thrice at intervals within two weeks
  • Chilli pepper powder -When used as a foliar spray or worked into the topsoil stimulates roots helps keeps worms from devouring plant roots.

Cost-effectiveness of DIY Natural Soil Amendments

DIY natural soil amendments have been gaining popularity in recent years due to their many benefits. They are not only safe and non-toxic but also cost-effective. While there are commercial alternatives available, they often come at a higher cost.

Comparing the costs of DIY and commercial soil amendments

Commercial soil amendments can be expensive, and they often contain synthetic chemicals that may harm the environment. On the other hand, DIY natural soil amendments are much more affordable and can be made from readily available materials found in most households.

For example, composting is a simple process that anyone can do with kitchen or yard waste such as fruit peels, eggshells or dead leaves. This can provide you with a rich source of nutrients for your plants without having to spend any extra money.

Another example is using Epsom salt as a natural source of magnesium for your plants instead of purchasing expensive chemical fertilizers. One pound of Epsom salt only costs a few dollars and can last an entire season depending on how much you use.

It’s important to note that while some DIY natural soil amendments may require more effort upfront, they provide long-term savings that can quickly add up over time.

Practical tips for saving money on DIY natural soil amendments

In addition to being cost-effective overall, there are ways to make DIY natural soil amendments even more budget-friendly:

Using household and backyard waste to make natural soil amendments

As mentioned previously, composting is one way to turn kitchen and yard waste into nutrient-rich fertilizer for your garden. Here are some additional ideas for making use of household and backyard waste:

  • Use old coffee grounds as a nitrogen-rich addition to your compost pile.
  • Crushed eggshells provide valuable calcium for plants.
  • Banana peels break down easily and make great compost.

By utilizing items that would otherwise be thrown away, you can reduce waste and save money on buying expensive fertilizers.

Finding natural soil amendments in nature

Another way to save money on DIY natural soil amendments is to look for ingredients directly in nature. Some ideas include:

  • Collecting fallen leaves from nearby trees can provide a rich source of carbon for your compost pile.
  • Seaweed found at the beach contains valuable micronutrients and minerals such as potassium, magnesium, and calcium.
  • Pine needles can also be added to compost piles or used as mulch around acid-loving plants.

Before collecting any materials from nature, make sure it is legal to do so in your area and avoid areas treated with pesticides or other harmful chemicals.

By taking advantage of these readily available natural resources, you can cut down on the costs of making DIY natural soil amendments.

Environmental Benefits of DIY Natural Soil Amendments

Using natural soil amendments is becoming increasingly popular due to its many benefits, not just for the health and productivity of your plants, but for the environment as well. Here are some examples of how choosing to use DIY natural soil amendments can benefit the planet:

Reduced carbon footprint

The use of synthetic fertilizers and pesticides in agriculture increases greenhouse gas emissions, contributing to climate change. By choosing DIY natural soil amendments over store-bought chemical options, you can significantly lower your carbon footprint.

Decreased energy consumption

The production and transportation of synthetic fertilizers and pesticides require significant amounts of fossil fuels. Choosing to make your own natural soil amendments or purchasing local organic alternatives can greatly reduce the amount of energy consumed in the process.

Greater waste diversion from landfills

DIY natural soil amendment ingredients such as food scraps and yard waste are often thrown into landfills where they produce methane, a potent greenhouse gas that contributes to climate change. By using these materials instead for composting or other natural soil amendment methods, we reduce the overall waste sent to landfills.

Safer for wildlife and pets

Synthetic chemicals commonly found in fertilizers and pesticides can be harmful to wildlife such as birds and insects that come into contact with treated plants. These chemicals may also endanger pets who roam yards treated with these products.

Lower likelihood of polluting the environment

Synthetic chemicals used in agriculture have been linked to water pollution through runoff and leaching into groundwater reserves. Choosing more eco-friendly alternatives like DIY natural soil amendments helps lower this risk by reducing overall chemical usage.

DIY Natural Soil Amendments Help Growth of Microorganisms

Soil is a complex system with numerous organisms that work in harmony to support plant life. Beneficial microorganisms play a vital role in enriching the soil and providing nutrients for plant growth. However, unhealthy soil can cause poor plant growth, low yield, and accumulation of chemicals that may be toxic for plants.

Luckily, there are many DIY natural soil amendments you can use to improve the overall health of your garden soil. These amendments not only provide nutrients but also help promote the growth of beneficial microorganisms.

Types of Beneficial Microorganisms Found in Healthy Soil

Microbes play a vital role in sustaining life on our planet by breaking down organic matter into simple compounds that plants can absorb as nutrients. Some beneficial microorganisms commonly found in healthy soils include:


Bacteria are one-celled organisms that make up a large portion of the microbial community. They help to break down organic matter, fix nitrogen from the atmosphere into a form that plants can absorb, and release carbon dioxide during respiration.

Some examples of beneficial bacteria include Lactobacillus spp., Bacillus spp., Rhizobium spp., Streptomyces spp., and Pseudomonas fluorescens.


Fungi are multicellular organisms with long branching threads called hyphae that grow through organic matter such as wood or leaves. They help break down tough, woody elements by secreting enzymes that dissolve cellulose and lignin.

Some examples of beneficial fungi include mycorrhizae, which form symbiotic associations with plant roots to enhance nutrient uptake. Other fungi such as Trichoderma spp., Penicillium chrysogenum and Aspergillus niger help suppress pathogens by producing natural antifungal compounds.


Nematodes are tiny worm-like organisms that can be either beneficial or harmful. The ones that are of interest to gardeners are known as predatory nematodes; they feed on other soil-dwelling pests such as grubs and flies, thereby keeping their population under control.

Other types of beneficial microorganisms include protozoa, archaea, actinomycetes, and algae. A healthy soil ecosystem comprises all these different microorganisms working together to improve soil fertility.

How DIY Natural Soil Amendments Provide Nutrient-rich Soil for Microorganisms

The use of natural soil amendments is one effective way to promote healthy microbial activity in the soil. There are several ways in which these amendments work:

Decomposition and Mineralization

Organic matter is an essential component of healthy soils because it provides energy and nutrients for the microbial community. Natural soil amendments such as compost, manure, and leaf mold provide organic matter that breaks down into simpler forms through decomposition.

During decomposition, microbes break down complex organic molecules into simpler ones like nitrogen (N), Phosphorous (P), Potassium (K), and other trace elements needed by plants. This process is called mineralization. Mineralization releases nutrients stored inside the organic molecules trapped inside mulch materials such as leaves, stems from cover crops or kitchen waste from compost bins.

As a result of mineralization process phosphorus becomes available in a form accessible by plant roots thus leading to growth enhancement and development during early stage formation phase contributing greatly to productivity/quality yields.

Soils rich in organic matter content generally have higher amounts of beneficial microorganisms living within them compared to conventionally managed soils that contain high amounts of chemical fertilizers which make the soils infertile over time due to mono-crop farming practices that do not allow time for recovery or rejuvenation).

Aerating the Soil

Soil compaction restricts root growth by limits infiltration of air and water, creating a hostile environment in the soil. Heavy traffic from foot or machine often causes stress on the soil structure which leads to hard pans that become impermeable to root penetration. Overtime plant growth capacity diminishes as roots suffocate under compacted soils.

To address this problem, you can use DIY natural amendments such as vermicomposting products, perlite or pumice stone to aerate your soil. They provide sufficient air space within the substrate that improves drainage and enhances water retention capacity leading to improved root establishment.

This promotes healthy microbial activity by providing larger surface area for microbes to colonize leading to increased microbial respiration and carbon dioxide emissions into air spaces created between aggregations of soil particles during tilling operations.

Types of DIY Natural Soil Amendments

Green manure

Green manure is an organic soil amendment that helps to enhance the fertility of soils through the addition of green vegetation. It contains essential nutrients that are beneficial to plant growth and can help to improve soil structure.

Green manure should be grown in a specific area before being harvested for use as a natural soil amendment. Popular types of green manure include crimson clover, vetch, fava beans, and rye grass. Once these plants have sufficiently grown, they are then cut down and dug into the soil.

Benefits of using green manure:

  • Adds organic matter to soil that can help improve its structure
  • Adds nutrients such as nitrogen, potassium, phosphorus and trace elements that are important for plant growth
  • Helps reduce erosion
  • Suppresses weed growth


Compost is one of the most popular natural soil amendments available today and is made from decomposed organic matter such as food scraps, leaves, and grass clippings. Composting is a simple process by which these materials break down over time with the help of bacteria and microorganisms.

Compost enhances soil structure by making it more porous which better allows water and air to penetrate the surface. This improved structure helps make it easier for roots to absorb nutrients from the surrounding environment.

Benefits of using compost:

  • Supports healthy root growth
  • Improves aeration in heavy soils which promotes water drainage
  • Increases nutrient availability
  • Reduces dependence on harmful chemical fertilizers

Worm Castings

Worm castings or vermicompost are worm excretions produced when worms digest organic matter such as food waste or dead plant material. Vermicomposting typically requires less maintenance than traditional composting because worms will feed on their own without much outside assistance.

Using this natural soil amendment brings many benefits that help increase nutrient levels in plants while also improving overall soil quality. Worm castings also help support beneficial microorganisms and can naturally suppress plant disease.

Benefits of using worm castings:

  • Provides a slow-release of nutrients which makes them available over time
  • Increases soil porosity which helps promote good drainage
  • Boosts the presence of beneficial bacteria in the soil
  • Reduces waste by utilizing food scraps


Biochar is made from burning organic material such as wood chips or agricultural waste at high temperatures in a process called pyrolysis. This natural soil amendment has a high level of carbon that helps to improve soil fertility and overall health.

The addition of biochar to soil helps promote plant health by improving water retention, reducing acidity levels, and increasing nutrient availability. Biochar is ideal for use in planting trees, flowers, fruits, vegetables, and shrubs.

Benefits of using biochar:

  • Improves water retention while assisting with healthy root growth
  • Increases nutrient availability as it acts like a sponge capturing minerals for later release into the environment
  • Reduces greenhouse gas emissions into the atmosphere by putting carbon back into the soil instead.
  • Improves soil structure promoting better tilth

Wood Ash

Wood ash is created when wood products are burned at high temperatures. It contains various essential nutrients such as calcium, potassium, magnesium, phosphorus that are important for plant growth.

The application of wood ash should be done with caution due to its alkaline nature – it’s important not to add too much on acidic soils where pH might get shifted dramatically towards neutral or beyond what some plants tolerate.

Benefits of using wood ash:

  • Contains valuable minerals that help nurture healthy plants
  • Can help increase pH levels thus reducing acidity
  • Is an effective insect repellent when applied directly into crevices – good against slugs and snails

Incorporating natural materials as a DIY solution where possible is an excellent way to promote healthy living practices around your garden. By consciously making choices to remove harmful additives and synthetic fertilizers, natural soil amendments can provide the benefits necessary for a thriving garden while also reducing environmental impact.

How to Make DIY Natural Soil Amendments


Composting is the simplest and most popular way to make natural soil amendments. All you need is organic matter (kitchen scraps, yard waste, and manure) and a compost bin or pile.

To make compost:

  1. Choose a dry spot in your backyard where you would like to set up a compost bin or pile.
  2. Add a mix of brown materials (dry leaves, twigs, shredded paper) and green materials (fruit and vegetable scraps, grass clippings).
  3. Water the pile regularly to keep it moist.
  4. Turn the pile every few weeks using a pitchfork or shovel to aerate it.
  5. After 2-6 months, depending on the size of your pile and environmental factors like temperature, you will have rich black compost that’s ready to be added to your garden soil.

Compost can improve your soil fertility by adding nutrients and beneficial microorganisms that help plants grow better.


Vermiculture is simply worm farming. It involves using worms to break down organic food scraps into nutrient-rich fertilizer known as worm castings.

To start vermiculture:

  1. Choose a shady spot for your worm bin that’s protected from direct sunlight.
  2. Buy red wiggler worms online or from a local gardening store.
  3. Fill the bottom of your bin with damp bedding material such as shredded newspaper or coconut coir.
  4. Add some kitchen scraps on top of the bedding material.
  5. Cover the scraps with another layer of damp bedding material and repeat until all the scraps have been added.
  6. Once per week remove any undecomposed food scraps from the bin.

Over time the worms will eat their way through this mixture until there is nothing left but rich vermicompost which can be used in place of regular potting soil mixes for growing plants indoors.

Making a green manure

A green manure is a type of cover crop that’s grown specifically to be turned into the soil and help improve its health. Since it is extremely cheap, easy to plant, and completely organic, a lot of gardeners use this technique to add fertility to their gardens or farms.

To make your own green manure:

  1. Choose a type of green manure based on your soil needs.
  2. Prepare the bed by removing weeds and debris and breaking up any clumps in the soil.
  3. Sow seeds evenly across the entire surface of your garden plot.
  4. Use a rake or hoe to mix the seeds with soil for improved seed-to-soil contact.
  5. Water thoroughly but gently.

Green manuring helps improve soil structure, adds nutrients like nitrogen, phosphorus and potassium when plants decompose into the soil which improves yields for future crops Also it reduces weed pressure over time which in turn reduces labour required for hand-weeding.

Building a biochar pit or kiln

Biochar is essentially charcoal that has been formed using organic material such as wood chips or sawdust through pyrolysis (heating without oxygen). This charcoal can then be added directly to soil as an amendment, thanks to its stable carbon content and high nutrient-holding capacity.

To build a biochar pit:

  1. Choose an open location with good drainage where building fire is allowed if you are going for pit method. For the kiln set-up please look up online DIY instructions
  2. Collect dry wood from dead trees preferably hardwood if available
  3. Arrange 1-2ft layer of woods onto ground at bottom form tepee shape while coming up making sure there are space between couple wood logs for air circulation
  4. Cover this pile with cardboard or straw5 on top Add dried leaves, grass clippings, hay etc all around evenly spread until you have a layer several inches thick.
  5. Ignite the pile from top – you will have to keep adding dry woods till solid coals appear and assuming no smoke is emerging any longer
  6. After 20-30 minutes or once temperature reaches about 350 degrees Celsius, douse the flames using soil in plentiful amount(you might need to get help of some one to put out fire effectively)
  7. Wait for char present underneath the soil layer maybe couple of days, after its done sifting should follow so that small particulate matter is not missed.

Adding biochar can improve your soil’s water holding capacity, retain nutrients and microorganisms and mitigate climate change by reducing carbon in the atmosphere.

Making wood ash

Wood ash a rich source of potassium carbonate which improves root growth, disease resistance, and overall plant vigor when added to soil either directly or through compost. When hardwoods are burnt for heat or fuel surprisingly large amounts of nutrient-dense wood ash are generated that when used properly is valuable to plants

To make your own wood ash:

  1. Simple burn branches, twigs or other prunings preferably hardwood available adding new material time-to-time.
  2. Let it all burn completely until everything has turned into ashes and white-coloured powder form.
  3. Wait until it’s cool then carefully transfer the powdery ash into a container with lid

Sprinkling this around plants as per requirement helps prevent diseases that evolved in acidic environments while also improving overall soil fertility.
