organic fertilizer types

There are different types of organic fertilizers you can use for the healthy growth of crops in your field.

Organic fertilizers come from organic materials like plants, animals, or mineral sources.

However, unlike traditional chemical fertilizers. organic fertilizers occur naturally.

The organic fertilizers and their type depend on the type of crop you are growing, however, in most cases, the organic fertilizers consist of a single ingredient.

An important thing to keep in mind is that the nutritional and ingredient value of organic fertilizers does not provide an immediate fix for your crops.

Rather, they break down slowly in order for plants to absorb the nutrients while at the same time providing nutrients for the soil.

 

Thus, organic fertilizers are eco-friendly and are more preferable to inorganic fertilizers.

The main examples of organic fertilizers are fish extracts. plant waste, animal waste, treated sewerage, and peat, etc.

Essential Nutrients for Agriculture

According to many scientists and agriculturists, S 16 essential nutrients are required for the better yield of crops.

Moreover, they grouped them according to the relative amount of each that plants need:

  • Primary nutrients, also known as macronutrients, are those usually required in the largest amounts. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and potassium.
  • Secondary nutrients are those usually needed in moderate amounts compared to the primary essential nutrients. The secondary nutrients are calcium, magnesium, and sulfur.
  • Micro- or trace nutrients are required in tiny amounts compared to primary or secondary nutrients. Micronutrients are boron, chlorine, copper, iron, manganese, molybdenum, and zinc.

However, very few plants need five other nutrients: cobalt, nickel, silicon, sodium, and vanadium.

Different Types of Organic Fertilizers

There are different types of organic fertilizers that you can obtain from vegetables or plant matter, animal waste, or minerals, etc.

Organic fertilizers are also known as farm manure and mostly refer to compost made from animal waste, or both animal and plant residue.

This residue is rich in natural by-products.

These include manure, bone meal, blood meal, shellfish fertilizers, sea bird guano, bat guano, fish emulsion, greensand, and rock phosphate.

Let’s discuss these as follows:

Manure

It is one of the many types of organic fertilizers that farmers use in gardens,

It comes from the waste of cows, sheep, horses, poultry, and cattle.

Moreover, manure is easier to process and produce as it comes from the excreta with some litter material.

organic fertilizer types, manure

Most often, manure is often termed as complete fertilizer because it contains a lot of nutrients.

However, manure has very low nutrient concentration thus making them valuable as an organic soil improvement element.

Therefore, it needs to be composted or properly prepared as the use of fresh manure has harmful effects on the plants.

Bone Meal

As the name refers, bone meal fertilizer is an organic fertilizer that comes from the fine grounding of bones.

These bones come from cattle and animal bones the remains from the slaughterhouses and are also a vital source of calcium.

Moreover, they contain almost 15% phosphate.

One of the benefits of using bone meal is that it stimulates flowering and the growth of a strong root system.

Thus, its major application is to fertilize flowering bulbs, flowers, and fruit trees.

Blood Meal

Blood meal refers to the blood of animals in powdered and dried form.

This blood comes from usually from the slaughterhouses and is an organic fertilizer.

It is one of the beneficial organic fertilizers because it is rich in nitrogen content. Therefore, blood is a beneficial organic fertilizer especially for promoting green leafy growth.

Its usage and application are usually through spay or sprinklers, as over-application can often contribute to the burning of the plant root.

ShellFish Fertilizer

As the name suggests, shellfish fertilizer comes from the processing of shells or bones of shellfish and crabs.

Just as bone meal, shellfish fertilizers are rich in calcium and also contain a considerable amount of phosphorus.

Along with these potential nutrients, it contains other traces of mines as well.

Therefore, it aids in the stimulation of flowering and the growth of a strong root system.

Furthermore, it contains chitin which helps to promote the growth of organisms that inhabit destructive roundworm pests.

Seabird Guano

It contains the excrement of seabirds that are accumulated from the shores.

Seabird excrements usually accumulate in the rock read od arid Sea Islands as these regions every minimum rainfall and decomposition.

Moreover, seabird Guano contains high amounts of nutrients like nitrogen, phosphorus, potassium, and other trace elements.

These nutrients are, therefore, good for flowering plants and help to promote the growth of strong root systems.

Bat Guano

Bat Guano comes from the accumulation of excrement of cave-dwelling bats.

These nutrients are protected by the caves from leaching which makes it a very beneficial source of organic fertilizer.

Moreover, it is highly rich in soluble phosphorus, nitrogen, potassium, and trace elements.

These all are good for the growth of your crops.

As these are present in powder form, you can easily apply them and often throughout the year.

Many farmers apply them as topdressing or as a foliar spray by diluting them in tea for the growth of their crops.

Fish Emulsion

Fish Emulsion comes from the processing of decomposed fish in powder form.

Moreover, the fish emulsion contains high levels of calcium and a considerable amount of phosphorus along with some other trace minerals.

Thus, they are important for stimulating the flowering of plants and the growth of strong root systems.

However, it is important o note that using a high amount of fish emulsion can harm your crops, just like manure and blood meal.

Compost and Cottonseed Meal

Both compost and cottonseed meal are plant-based fertilizers.

Compost is rich in nutrients and is an excellent soil improver that helps to promote organic matter and the fertility of the soil.

Moreover, it is rich in beneficial nutrients for plants that help to retain water for a long period of time in the soil.

Cottonseed meal is, however, rich in nitrogen and also contains lower concentrations of phosphorus and potassium.

There are excellent fertilizers for grass and many farmers use them to regulate the soil and its environment.

Greensand

It is an olive-green sandstone that contains glauconite or iron potassium silicate.

It comes from the sea deposits of the shells and is also very rich in important nutrients.

These nutrients are potassium, iron, and over different micronutrients.

Moreover, it aids in the stimulation of flowering and fruition in fruit trees.

Rock Phosphate

Rock phosphate is a rock that contains lime-phosphate or calcium.

It is often present in the form of grounds or powder and is one of the beneficial fertilizers for your crops.

It results from the accumulation of animal waste through the process of sedimentation and soil compaction.

Moreover, it contains above 30% phosphate along with high concentrations of trace micronutrients.

One of the advantages of using this as a fertilizer is that it does not leach and thus, remains in its original state.

This happens until the reports of the plants absorb it and thus encourage the healthy growth of your crops.

Soybean meal and Seaweed

Soybean is high in beneficial nutrients like nitrogen, phosphorus, and neutral pH. Moreover, it is a functional additive for soil maintenance for longer periods of time.

While seaweed is an immediate-release fertilizer and thus is an excellent source of zin and iron for the crops.

Moreover, it is very effective for high-potash crops.
