How to make organic fertilizer at home

 Blog  •  Published on: 01 Apr 2023

If you are an avid gardener, you know the importance of soil quality in determining the health and productivity of your plants. While chemical fertilizers can provide a quick boost to your soil's nutrient levels, they can also have negative long-term effects on the environment and your health. Organic fertilizers, on the other hand, are made from natural materials and can improve soil health without harmful side effects.

Making organic fertilizer at home is an easy and cost-effective way to boost soil fertility and support a healthy garden. By using natural ingredients, you can ensure that your fertilizer is free from harmful chemicals and tailored to the specific needs of your plants. In this article, we will guide you through the steps of making organic fertilizer at home, including the necessary ingredients, tools, and techniques.

Why use organic fertilizer over chemical fertilizers?

Chemical fertilizers are a quick and easy solution to increase soil fertility, but as we already mentioned, they can have negative impacts on the environment and human health. They are made of synthetic chemicals that can cause soil degradation, water pollution, and health problems in both humans and animals.

Organic fertilizers are made from natural materials like plant and animal waste, which are rich in nutrients that can help plants grow. These fertilizers not only improve soil health, but also support biodiversity and ecosystem function. Also, organic fertilizers are often cheaper than chemical fertilizers and can be made at home with simple ingredients.

Additionally, organic fertilizers are known for their slow release of nutrients, which provides a constant supply of nutrients to the soil and plants over time. This is in contrast to chemical fertilizers, which can lead to nutrient imbalances, overfertilization, and damage to plant roots.

Organic fertilizers can also help build soil structure and improve water retention, resulting in healthier plants with stronger root systems. Finally, organic fertilizers are a sustainable and ecological option that supports the natural cycle of nutrients, reducing the need for synthetic inputs and minimizing the environmental impact of agricultural and gardening practices.

What are the basic ingredients for making organic fertilizer at home?

Organic fertilizers can be made from a wide range of natural materials, including plant and animal waste, minerals, and compost. Some of the basic ingredients for making organic fertilizer at home include:

  • Compost: Compost is a nutrient-rich soil amendment made from decomposed organic matter, such as leaves, grass clippings, and food scraps. Compost is an excellent source of nitrogen, phosphorus, and potassium, and it can be used as a base for making organic fertilizers.
  • Manure: Animal manure, such as cow, horse, or chicken manure, is a rich source of nutrients, including nitrogen, phosphorus, and potassium. Manure can be used on its own or mixed with other organic materials to make a complete organic fertilizer.
  • Bone meal: Bone meal is a finely ground powder made from animal bones that are high in phosphorus and calcium. It can be added to compost or mixed with other organic materials to provide a slow-release source of nutrients.
  • Blood meal: Blood meal is a dry, powdery substance made from dried animal blood that is high in nitrogen. It can be used as a quick-release source of nitrogen in organic fertilizers.
  • Fish emulsion: Fish emulsion is a liquid fertilizer made from fish waste that is high in nitrogen and other trace minerals. It can be added to soil or sprayed directly on plants to provide a quick boost of nutrients.
  • Epsom salt: Epsom salt is a natural mineral compound made from magnesium and sulfate. It can be added to compost or mixed with other organic materials to provide a source of magnesium, which is essential for plant growth.

These ingredients can be mixed and matched to create a variety of organic fertilizers that meet the specific needs of your plants. The key is to use high-quality, natural materials and to ensure that the fertilizer is properly balanced in terms of nutrients.

How to make organic fertilizer at home?

Making organic fertilizer at home is a simple and cost-effective way to support healthy soil and plant growth. Here are a few methods for making organic fertilizer at home:

  • Compost-based organic fertilizer: To make compost-based organic fertilizer, start by creating a compost pile using a mix of green and brown materials. Green materials, such as grass clippings and vegetable scraps, provide nitrogen, while brown materials, such as leaves and twigs, provide carbon. Once your compost is fully decomposed, mix it with bone meal, blood meal, or other organic materials to create a nutrient-rich fertilizer.
  • Manure-based organic fertilizer: To make manure-based organic fertilizer, start by collecting animal manure from a reliable source, such as a local farm or stable. Mix the manure with bedding materials, such as straw or sawdust, to create a compost pile. Once the compost has fully decomposed, mix it with other organic materials, such as bone meal or fish emulsion, to create a balanced fertilizer.
  • Fish emulsion fertilizer: To make fish emulsion fertilizer, start by collecting fish waste, such as fish heads or scraps, and mixing them with water in a 5:1 ratio (water to fish waste). Allow the mixture to steep for several weeks, stirring occasionally, until it turns dark and has a strong fishy odor. Strain the liquid through a cheesecloth or fine mesh strainer and dilute it with water at a ratio of 1:4 (fish emulsion to water). Use the diluted mixture to water plants or spray directly on leaves.
  • Epsom salt fertilizer: To make Epsom salt fertilizer, dissolve 1 tablespoon of Epsom salt in 1 gallon of water. Use the mixture to water plants or spray directly on leaves. This can provide a quick source of magnesium, which is essential for plant growth.

Regardless of the method you choose, it is important to apply organic fertilizer sparingly and to follow the recommended application rates for your specific plants. With a little time and effort, you can create nutrient-rich organic fertilizers at home that will support healthy soil and vibrant plant growth.
