Jeevamrut Preparation: Liquid Organic Manure for Soil Microbial Health

Jeevamrut, also known as Jeevamrutha, is a popular liquid organic formulation used in natural farming across India. It is not a direct fertilizer that supplies macronutrients like nitrogen or phosphorus. Instead, it is a powerful culture of beneficial soil microorganisms that helps activate the biological activity of the soil, making locked up nutrients available to plants. Over years of chemical farming, many beneficial soil microbes have died, leaving the soil hard and unproductive. Jeevamrut acts as an activator, bringing the soil back to life. It is cheap to make, utilizes local farm resources, and is suitable for all crops, including grain crops, vegetables, and fruit orchards.

The adoption of Jeevamrut is a key step towards reducing a farmer's dependence on expensive chemical fertilizers like urea and DAP. In many parts of India, soil health has degraded due to the continuous application of synthetic chemicals, leading to declining crop responses. By introducing millions of beneficial microbes through this liquid manure, farmers can rebuild the natural fertility of their land. The preparation process is simple, cost effective, and utilizes materials that are easily available on any traditional farm, making it an ideal practice for small and marginal landholders.

What Is Jeevamrut Liquid Manure

To get the best results, it is important to understand the biological nature of this liquid formulation. Unlike compost or farmyard manure, which take months to decompose and supply nutrients, Jeevamrut is a fast acting microbial broth. The ingredients used in its preparation do not serve as direct plant nutrients; instead, they act as food for the microorganisms present in the cow dung and the forest soil. When these microbes are given the right environment, they multiply at an astronomical rate, creating a concentrated liquid culture ready to colonize the field.

Once applied to the soil, these microorganisms go to work immediately. They break down organic residues, release bound nutrients, and improve the physical structure of the soil. Over time, regular application makes the soil loose, porous, and increases its capacity to retain water. This is particularly beneficial in dryland farming areas where water conservation is critical. The liquid can be applied to all types of crops during different growth stages, providing a constant supply of active microbes to the root zone.

The Philosophy of Jeevamrutha

The core philosophy behind Jeevamrut is to mimic natural forest ecosystems. In a forest, no one applies chemical fertilizers or pesticides, yet trees grow huge and healthy. This is because soil microbes constantly break down organic matter and feed the roots. Jeevamrut aims to reintroduce this microbial loop into cultivated fields. By focusing on soil health rather than feeding the plant directly, natural farming builds a resilient agricultural system that can withstand dry spells, heavy rains, and pest attacks.

This system also promotes biodiversity in the soil. Healthy soil is home to earthworms, beneficial fungi, and bacteria that work together to maintain soil structure and health. Applying chemical inputs disrupts this delicate ecosystem, while organic applications like Jeevamrut support it. By nurturing this underground community, farmers can establish a self sustaining soil cycle that requires fewer inputs and yields healthier crops season after season.

Essential Ingredients and Ratios

To prepare a standard batch of 200 litres of Jeevamrut, which is sufficient for one acre of land, you need specific ingredients in correct proportions. Using the right ratios ensures that the microorganisms have enough food to multiply without causing the mixture to spoil. Fresh and high quality ingredients are crucial for obtaining a high microbial count. Below is the list of ingredients required to prepare a single 200 litre batch.

The container used for preparation should be large enough to hold 200 litres of liquid with some empty space at the top. A plastic drum is ideal for this purpose. Avoid using metal containers, especially those made of iron, copper, or aluminium. The organic acids produced during the fermentation process can react with metal surfaces, releasing toxic compounds that can kill the beneficial bacteria and damage your soil.

Cow Dung and Urine

You need 10 kilograms of fresh cow dung and 5 to 10 litres of cow urine. Dung from local indigenous cow breeds (Desi cows) is highly recommended because it contains a much higher concentration of beneficial bacteria compared to exotic crossbred cows. The dung should be fresh, ideally collected within 24 hours of preparation. The urine acts as a natural source of nitrogen and acts as a mild pest repellent, and older, concentrated urine is often preferred as it has a higher microbial activation potential.

If indigenous cow dung is not available, you can use dung from other farm animals, but the microbial diversity may be lower. Avoid using dung from animals that have been treated with heavy doses of antibiotics, as chemical residues in the dung can inhibit the growth of beneficial soil bacteria. Collect the ingredients in clean buckets and keep them covered until you are ready to start the mixing process.

Jaggery and Pulse Flour

You will also need 2 kilograms of organic jaggery (gur) and 2 kilograms of pulse flour (besan or flour made from chickpea, pigeon pea, or black gram). Jaggery serves as a rich carbon source, while the pulse flour provides proteins. Together, they act as food to multiply the microorganisms present in the mixture. Do not use chemical sugar or highly refined white sugar, as they lack the trace minerals found in dark, unrefined organic jaggery.

Any locally available pulse flour can be used. Chickpea flour (besan) is the most popular choice because it dissolves easily and provides a balanced protein profile. If pulses are expensive, you can use flour from split pulses or damaged grains that are unfit for human consumption. Ensure the flour is ground finely so it mixes smoothly with water without forming dry lumps that can float on the surface and attract flies.

Undisturbed Forest Soil

Finally, you need a handful (about 100 to 200 grams) of undisturbed soil, preferably collected from the root zone of a banyan tree or from the edge of an old forest. This soil contains diverse, native strains of beneficial fungi and bacteria that have not been exposed to chemical fertilizers or pesticides. This small sample acts as the mother culture, introducing the necessary biological diversity into the fermentation drum.

When collecting this soil, scrape away the dry leaf litter from the surface and take the moist, dark topsoil from the top couple of inches. The root zone of large, old trees is ideal because these trees host a rich network of mycorrhizal fungi and beneficial bacteria. Avoid taking soil from fields where chemical weedicides or fertilizers have been applied recently, as these chemicals can reduce the variety of living organisms in your starter culture.

Step by Step Fermentation Process

Once you have gathered all the ingredients, you can start the fermentation process. Fill the 200 litre plastic drum with about 180 litres of clean, chlorine free water. Well water, borewell water, or pond water is ideal. If you must use municipal tap water, let it sit in an open container for 24 hours to allow the chlorine to evaporate, as chlorine is a sanitizer that will kill the beneficial microbes in your mix.

In a separate bucket, mix the 10 kilograms of cow dung and 5 to 10 litres of cow urine with a few litres of water. Use your hands or a wooden stick to stir the mixture until it forms a smooth, lump free slurry. Pouring this slurry directly into the drum ensures that the dung particles suspend evenly in the water, allowing the bacteria to access the dissolved nutrients quickly.

Mixing and Stirring Protocol

Next, dissolve the 2 kilograms of jaggery in a bucket of water. In another bucket, mix the 2 kilograms of pulse flour with water to make a thin paste, ensuring there are no dry pockets of flour. Add the dissolved jaggery, pulse flour paste, and the handful of forest soil to the drum. Stir the entire mixture thoroughly using a long wooden stick. The stirring should be vigorous, moving in a clockwise direction for a few minutes, followed by a counter clockwise direction.

This dual direction stirring helps dissolve the ingredients completely and aerates the liquid. Aeration is critical because the most beneficial soil bacteria, such as nitrogen fixers and phosphate solubilizers, are aerobic, meaning they need oxygen to grow. Stirring the mixture twice daily, once in the morning and once in the evening, keeps the oxygen levels high and prevents the solid dung particles from settling at the bottom.

Temperature and Shade Requirements

Place the drum under a thick shade, such as under a tree or inside a thatched shed. Never expose the drum to direct sunlight, as high temperatures and ultraviolet radiation can kill the delicate microbial cells. The ideal temperature for fermentation is between 25 and 35 degrees Celsius. Cover the mouth of the drum with a wet gunny bag or a breathable cotton cloth to keep flies out while allowing air to flow freely.

The wet gunny bag also helps maintain a cool temperature inside the drum through evaporative cooling. During the hot summer months, you may need to sprinkle water on the gunny bag occasionally to keep it moist. Under these shaded, aerated conditions, the fermentation process takes about 4 to 7 days, depending on the ambient temperature, after which the liquid is ready for field application.

Soil Microbial Benefits

During the fermentation process, the bacteria and fungi from the forest soil feed on the jaggery and pulse flour. They multiply rapidly, turning the mixture into a rich microbial broth. When applied to the soil, these microbes decompose organic matter, release bound phosphorus, fix atmospheric nitrogen, and improve the soil's water holding capacity. This biological activity stimulates root growth and helps the crop absorb nutrients more efficiently.

Regular application of Jeevamrut also helps suppress harmful soil pathogens. The beneficial bacteria colonize the root zone, competing with pathogens for space and nutrients. Some of these microbes secrete natural antibiotic substances that inhibit fungal diseases, protecting the crop from root rot and wilt. This biological protection reduces the need for chemical soil treatments, saving money and preserving soil health.

Methods of Field Application

Jeevamrut can be applied to the field using various methods depending on your irrigation setup. For a one acre field, 200 litres of Jeevamrut is the standard recommended dose. You can apply it once every 14 to 21 days during the cropping season for best results. The liquid can be applied directly to the soil, mixed with irrigation water, or sprayed on the crop leaves after filtration.

It is important to apply the liquid when the soil is moist. Soil moisture is essential for the survival and movement of the introduced microbes. Applying Jeevamrut to dry, hot soil will result in high microbial mortality, reducing the effectiveness of the treatment. Farmers should irrigate their fields lightly before application or apply the liquid immediately after a rainfall event.

Soil Drenching and Fertigation

The most common method is direct soil drenching around the root zone of the plants. You can also mix Jeevamrut with irrigation water. This is called fertigation. If you have a drip irrigation system, filter the mixture thoroughly through a fine cloth multiple times to remove any solid particles that could clog the drippers. This filtration is essential to prevent blockages in the narrow tubes and emitters of the drip system.

For flood irrigation, you can place the drum near the main water channel and let the liquid drip slowly into the flowing water. This ensures an even distribution of the microbial culture across the entire field. The flow rate of the drip should be adjusted so that the 200 litres of liquid is distributed evenly over the entire irrigated area during the watering cycle.

Foliar Spray Guidelines

You can also use Jeevamrut as a foliar spray to promote vegetative growth and protect leaves. Filter the liquid carefully and dilute it with water in a one to ten ratio (1 litre of Jeevamrut to 10 litres of water). Spray this mixture on the leaves during the early morning or late afternoon to avoid leaf burn from the hot sun. This foliar application provides micro nutrients and beneficial microbes to the leaf surface, helping suppress foliar diseases.

Foliar sprays are particularly useful during the active vegetative growth phase and flowering stage. The organic compounds in the spray are absorbed quickly by the leaves, giving the crop a healthy green color. Always use clean spray equipment, and avoid using tanks that have recently contained chemical herbicides or fungicides, as chemical residues can kill the live microbes in the spray liquid.

Storage Limits and Stability

Jeevamrut is a live bacterial culture, so it does not keep indefinitely. The microbial activity peaks between 4 to 7 days after preparation. You should use the entire batch within 10 to 12 days. After 12 days, the food source runs out, and the beneficial microbes start dying, reducing the effectiveness of the manure. Storing the liquid for too long can also lead to unpleasant odors and the growth of anaerobic bacteria.

If you cannot use the mixture within the recommended time, you can add a small amount of jaggery and water to keep the microbes alive for a few more days. However, it is best to prepare only the amount you need for immediate application. Freshly fermented Jeevamrut always provides the highest microbial count and the best results in the field. Discard any expired or foul smelling batches by pouring them onto compost heaps.

Financial Benefits and Cost Savings

Preparing Jeevamrut helps farmers reduce their expenses on chemical fertilizers like urea and DAP. By lowering input costs, it improves the net income from cultivation. For farmers seeking credit to expand their organic setups, banks offer agricultural loans. Note that NABARD refinances agricultural and allied loans through cooperative and commercial banks and does not provide direct loans to individual farmers. Working with your local bank can help you access credit for farm improvements.

By reducing the need for purchased chemical inputs, Jeevamrut increases the self reliance of smallholder farms. The money saved on chemical fertilizers can be reinvested in other productive assets like drip irrigation or quality seeds. This cost reduction is a key factor in improving farm profitability, especially during seasons when chemical fertilizer prices are high or supplies are limited.

NABARD Refinancing and Agri Loans

Farmers can check their crop loan eligibility on banking portals or calculate repayment schedules using a tractor loan or KCC calculator. Organic farming certification can also help secure better prices in specialized export markets. Banks look favorably on sustainable farming practices, as they reduce the risk of crop failure and improve the borrower's repayment capacity.

Specialized loan schemes are available for organic farmers to build compost pits, vermicompost units, and liquid manure preparation sheds. By presenting a clear farm plan that includes biological inputs, you can secure favorable interest rates under government backed credit programs, helping you transition to sustainable farming without facing financial stress.

Digital Schemes and Farmer ID

As the central government rolls out the Agristack project state by state, farmers should register on their state's land portal to get a Farmer ID. This ID helps in getting subsidies for organic certification, bio inputs, and accessing government schemes easily. West Bengal farmers can register on their state portal, where the state runs the premium free Bangla Shasya Bima (BSB) scheme instead of PMFBY. Keeping your digital records updated ensures that you can access all state and central agricultural benefits.
