Biofertilizer Law and Legal Definition
Biofertilizer refers to microorganisms that are naturally unfriendly towards certain pathogens or pests. It can be used to protect crops because of their antagonistic nature. A biofertilizer when applied to seed, plant surfaces, or soil, will colonize the rhizosphere or the interior of a plant and will promote growth of such plant by increasing the supply of primary nutrients to the host plant.
Biofertilizer fixes the atmospheric nitrogen, solubilize and mobilize phosphorus, translocate minor elements like zinc, and copper, to the plants. It helps to produce plant growth promoting hormones, vitamins and amino acids and also controls plant pathogenic fungi, thereby improving the soil health and crop production. Some of the biofertilizers that are used in agriculture are rhizabium, azotobacter, azospirillum and blue green algae (BGA).
