APlants require nitrogen mainly in the form of nitrate, which is exported from roots to shoots, reconverted to ammonium and assimilated as amino acid.
BRhizobia, cyanobacteria, nitrifying bacteria, symbiotic fungi, etc are used as biofertilizers.

DMaterials of biological origin which are commonly used to maintain and improve soil fertility are green manures, biofertilizers and bioinsecticides.
