Any living organism supplying plant nutrients directly or indirectly is regarded as biofertilizer. They are not synthetically manufactured in factory. Many organisms with a potentiality to supply plant nutrients - have been recognised. Use of biofertilizers has many advantages. ..

Soil's fertility is its capacity to sustain plant life with required nutrients. Fertility of soil decreases when the same crop is grown in the same land repeatedly, or by soil erosion. Erosion is the physical removal of soil particles from their original places and transportation to some other p..

(based on soil pH, available water, temperature). As there are large number of varying types of soils in varying climatic situations being used to grow varieties of crops with differing abilities to make use available nutrients, the expressions of crops in terms of their yield potentiality vary to ..

Soil is classified based on nature and composition. They are: Alluvial soil - rich in loam and clay Black soil - mostly made of clay Red soil - sandy to loam Mountain soil - stony, sandy soil Desert soil - sandy and poor in organic carbon Laterite soil - porous clay, rich in iron and aluminium hydr..

. Such bacteria are found - where grasses, cereals are grown. They fix atmospheric nitrogen and make it available to crops. Fixation of nitrogen by such bacteria may occur naturally in very ideal situation. But such fixation process may have to be enhanced by external application of bacterial cultu..
