ABSTRACT
Organic fertilizers are made entirely of plant and animal-based components. Organic materials serve as both fertilizers and soil conditioners and feed both soils and plants. Organic fertilizer will feed soil organisms producing plant food by converting into an available form. Plant-based fertilizers generally offer more in the way of soil conditioning than actual nutrients. Cow manure in rural areas is a major source of organic raw fertilizer. Many organic gardeners use compost to reduce or eliminate the need for fertilizers. The good quality of manure is ensured by suitable storing and curing (fermentation). Curing is to humificate the components of the manure and fermentation is carried out by microorganisms; this process sterilizes the manure and improves adequate C:N ratios (20:1) and reduces water content. The roots of cultivated plants play a significant role in the maintenance of fertility, digestion of nutrients, and improvement of the structure of soils. Organic fertilizers increase the productivity, growth, and quality of plants. It nourishes the organisms that cycle nutrients and compete with pests and pathogens. However, the use of organic fertilizers has some disadvantages too. Use of liquid fertilizers give plants a light nutrient boost during the growing season.
