Step-by-step solution
Organic fertilizers are derived from animal matter, animal excreta, human excreta, and vegetable matter (e.g., compost and crop residues).

Biofertilizers are preparations containing living cells or latent cells of efficient strains of microorganisms (bacteria, fungi, algae) that help crop plants' uptake of nutrients by their interactions in the rhizosphere, such as nitrogen fixation and phosphorus solubilization. Inorganic or chemical fertilizers
