Organic fertilizers are fertilizers derived from animal’s matters, animal excreta (manure), Human excreta and Plant/vegetable matters. (e.g compost and crop residues). Naturally occurring organic fertilizer include animal wastes from meat processing, peat, manure slurry. Be inform that majority of fertilizers used in commercial farming are extracted from minerals (e.g phosphate rock) or produce industrially (e.g Ammonia)
Most agricultural waste serves as a good soil conditional. They add nutrient to the plant and improve the soil condition. Most of these wastes are gotten in a raw form directly from the farm or mostly from agricultural produce processing companies
Because of low quantities of agricultural waste generated from different factories around us, it is difficult to produce organic fertilizers for commercial purposes. But it is highly recommended to be use for gardener (horticulture) and vegetable farming. Within short period of time, it revive the soils life and it decomposes to be part of the soil which makes it to add more value to the soil rather than concentrating on the growth of plant.
The manufacturing process of most chemical fertilizers depend on non renewable resources such as coal and natural gas, while others are made by treating rock minerals with acid to make them more soluble. Fortunately there are more and more truly organic fertilizer coming to the market and these products are made from natural plant and animal materials
As a gardener or vegetable farmers, you can try some of these organic fertilizer listed below. They are derived majorly from agricultural waste and its cheap, easy to use, slow release and low analysis.

In many part of the world, coconut husk is also useful to deter snails from delicate plantings and as a growing medium in intensive glasshouse (greenhouse) horticulture. It is mostly used as a substrate to grow mushrooms after processing, it is added to the soil and decomposed gradually to add nutritional value to the soil and also aid plant growth effectively
Cocoa bean shell: Mostly called cocoa mulch; when cocoa beans are roasted, the shell separates from the bean. The roasting process sterilized the shell so that they are weed free and organic. Many vegetable farmers and gardeners enjoy the sweet smell and attractive appearance of cocoa shell mulch and there are several other cocoa mulch benefits; organic cocoa mulch, contains nitrogen, phosphate and potash and pH value of 5.8 all these are more essential for the soil and mostly aid the plant growth. Using cocoa shell in the garden is an excellent way to increase soil vitality and is an attractive top cover for both flower beds and vegetables patches. It also help to retain moisture in garden beds and reduce weeds organically, eliminating the need for chemical-laden herbicides
