Organic fertilisers

Organic fertilisers

The term 'organic' refers to food or other materials produced through biological processes rather than chemical ones. These fertilizers are made from natural ingredients such as manure, compost, blood meal, bone meal, fish emulsion, seaweed extract, kelp meal, rock phosphate, etc.

Fertilizers play a vital role in growing crops. They provide nutrients to the soil and thus increase soil fertility and soil quality. There are several types of organic fertilizers available in the market. Let us discuss some of these below.

Organic fertilizers are often considered to be better for the environment because they don’t contain synthetic chemicals or pesticides. They also tend to be less expensive than their conventional counterparts.

Organic fertilizers are natural substances derived from plants or animal waste. They contain no synthetic chemicals and are considered safe. Organic fertilizers are also environmentally friendly because they don't pollute groundwater and soil.

Organic fertilizers are often preferred because they don't pollute the environment. They also reduce the risk of food poisoning. Some organic fertilizers are also rich in micronutrients, which are essential elements for plant growth.

Chemical fertilisers contain harmful elements such as arsenic, cadmium, chromium, mercury, lead, nitrates, phosphates, and sulfur. These heavy metals pose serious health risks to humans and animals. On the other hand, organic fertilizers are free from these toxins.

There are two types of organic fertilizers: compost and manure. Compost is created from kitchen waste or garden trimmings, whereas manure comes from animals. Both are rich in nutrients and can improve the quality of your soil. It also helps in maintaining soil stability.

Organic garden fertilizer is safe for plant health. The amount of fertilizer required depends on the type of plant and soil conditions. Apply them at least once every two weeks during the growing season.

Here are some common types of organic fertilizers:

Bone meal

Bone meal is used for fertilizer and is made from animal bones. The process of making bone meal involves grinding up bones into a powder, then mixing them with water until they form a paste. This mixture is dried, ground again, and mixed with other ingredients such as lime, gypsum, and salt. Bone meal is often used as a fertilizer for plants, especially crops like corn, wheat, and soybeans.

Bone meal is a fertilizer that contains calcium phosphate, which helps plant roots absorb nutrients. The best way to use bone meal is to sprinkle it around the base of plants, such as tomatoes, peppers, eggplant, and cucumbers.

Organic manures

Organic manure is a natural fertilizer made from animal waste such as urine, feces, and dung. The benefits of organic manure include no chemicals, no synthetic fertilizers, and no pesticides. Organic manure also has high levels of nitrogen, phosphorus, potassium, magnesium, calcium, sulfur, and trace elements.

Fresh manure is an organic fertilizer made from animal manure. They contain nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and trace elements such as iron, zinc, copper, and manganese. The nutrients in manure help plants grow faster, stronger, and healthier.

Chicken manure, cow manure, green manure, horse manure, goat manure are the different types of organic manure. They help in improving the soil structure.

Peat moss

Peat moss is an organic product obtained by decomposing sphagnum peat bogs. Peat moss is rich in humus, which makes it ideal for gardening. It's also good for mulching vegetables, trees, shrubs, and flowers.

Rock phosphate

Rock phosphate is a mineral source found in rock formations that contains phosphorus. This mineral is used for fertilizers and animal feed. It is an excellent source of phosphorus.

Liquid fertilizer

Liquid fertilizers are used for growing plants indoors. They contain nutrients such as nitrogen, phosphorus, potassium, and magnesium. The main advantage of using liquid fertilizer is that it is easy to apply and use. They help in root growth. It can also be used as a foliar spray.

Liquid fertilizers are made from natural ingredients such as fish meal, urea, and ammonium nitrate. They are used for growing plants like tomatoes, peppers, cucumbers, eggplants, and other vegetables. Liquid fertilizers are also used in animal feed. They are rich in nitrogen contents and help in plant nutrition.

Jeevamrutha is a type of liquid fertilizer prepared from cow urine and cow dung. It promotes plant growth.

Liquid fertilizer

Seaweed extract

Seaweed extract is a liquid fertilizer that contains minerals like phosphorous, potassium, and nitrogen. Seaweed extract is derived from seaweeds, which have been soaked in seawater.

The benefits of using seaweed extract as a fertilizer include being free of chemicals, having no side effects, and not harming the environment.

Alfalfa meal

Alfalfa meal is a natural fertilizer that contains nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, zinc, copper, manganese, and other nutrients. Alfalfa meal is used for soil improvement, plant growth promotion, and pest control.

Feather meal

Feather meal is a fertilizer used for growing plants such as corn, wheat, soybeans, and other crops. The main ingredient is chicken feathers which contain high levels of phosphorus, calcium, magnesium, zinc, and other minerals.

Feather meal is used for making fertilizer. The process of making fertilizer includes mixing the ingredients and then spreading them out evenly across the field. This mixture is called "feather meal".

Composting is the process of converting organic waste into compost. The compost is then used for gardening or landscaping purposes. There are two types of composters: aerobic and anaerobic.

Compost is organic material that has been decomposed by microorganisms. The process begins when food waste decomposes into a mixture of carbon dioxide, water, nitrogen, and other gases. This mixture then goes through a series of processes until it becomes soil.

Composting is a great way to recycle organic waste into soil for gardening. The process of composting breaks down organic matter such as food scraps, plant material like grass clippings, leaves, and manure into rich humus which is used to fertilize plants. This helps decompose the organic matter and release nutrients back into the soil.

Composting is a way to turn food waste into fertilizer for gardens. The process begins when organic matter such as food scraps and yard trimmings are added to a compost bin as compost piles. After about six weeks, the mixture becomes rich healthy soil for plants.



Vermicompost is a natural way to recycle food waste into rich soil for plants. The process uses worms to break down organic matter such as kitchen scraps, grass clippings, leaves, and other yard wastes. This helps reduce the amount of garbage going into landfills.

Vermicompost is a process where organic waste is turned into fertilizer for plants. The process begins when food scraps are mixed with worms and bacteria. Worms eat the food scraps and excrete earthworm castings which are then used as fertilizer. This method is much cheaper than using chemical fertilizers and much more eco-friendly.

Vermicompost is a natural way to recycle food waste into rich soil for plants. The process uses worms to break down organic matter such as kitchen scraps and garden trimmings. Worms eat food waste and excrete castings which contain nutrients essential for plant growth. It also helps in soil aeration.

The worm-based vermicomposting system consists of a container filled with worms and their food source. Food sources include kitchen scraps, grass clippers, leaves, and other organic materials. These materials are placed in the container and covered with dirt. Over time, the worms will eat the food waste and excrete nutrient-rich castings.


Citrus bio enzyme

Citrus bio enzymes are enzymes extracted from citrus fruits such as oranges, lemons, limes, grapefruits, tangerines, etc. Citrus waste is fermented to produce enzymes that help the plants in flowering and fruiting. It also helps in root development.

Citrus Bio Enzyme is a natural product derived from citrus peels. It contains enzymes that help in breaking down the cell walls of the roots of plants. It also helps in promoting the growth of the roots, stems, and branches of plants.
