Definition and Uses of Biological Fertilizer


Pengertian dan Kegunaan Pupuk Hayati

Biological fertilizer is engineered product that is useful for agricultural biotechnology. In general, the main content is beneficial microorganisms for soil fertility and plant growth both vegetative and generative. Biological fertilizer does not contain nitrogen, phosphate, and potassium. However, microorganisms contained in it, when in the soil can result in the tethered nitrogen from the air, outlines P and K are bound to other compounds.


Biological fertilizer is not an ordinary fertilizer that can directly improve soil fertility by adding nutrients to the soil. Biological fertilizers add nutrients through the natural processes, ie the fixation of atmospheric nitrogen, making of material dissolved phosphorus, and stimulating plant growth through the synthesis of substances that support plant growth. Microorganisms in biofertilizers restore natural nutrient cycles and soil organic material to form soil. Through the use of bio-fertilizers, healthy plants can be grown while improving sustainability and soil health.


Biological fertilizer is one very important ingredient in improving soil fertility. The use of bio-fertilizers will not leave residue on the plant that is safe for human health. In addition the use of biological fertilizers is expected to improve the health of the soil, spurring plant growth and increase crop production.
