BIOLOGICAL LEVELS, namely biological fertilizers that function to increase the amount of nutrients absorbed by plants (avaliable), increase the efficiency of nutrient absorption by plants (antagonists), these biological fertilizers contain at least 4 functional microbes such as: Aspergillus sp, Azotobacter sp, Azozpirillum sp, Bacillus sp , Pseudomanas sp.
Functional microbes function to fix nitrogen (N) functions from roots zone, release fixed Phosphorus (P) and fixed Potassium (K) from soil trap so that N, P, K fertilizers can be used economically in the cultivation of plants.
Functional microbes also produce growth regulator metabolite which functions to spur meristems metabolism on the growing point of shoots, buds, flowers, stolons, and stimulate the roots as to flourish well. Protect the roots against pests and diseases, as organic materials decomposer bio-activator and as an antidote for several heavy metals.
