Agriculture has seen major technological advances during the last three decades enhancing food production and achieving self-sufficiency. Use of the new agricultural technologies was accompanied by increasing inputs of chemical fertilizers increasing agricultural production. However, such indiscriminate use of chemical fertilizers also led to environmental pollution, erosion of soil quality and contamination of farm produce and groundwater by chemical fertilizer residues and consequent health hazards. Chemical fertilizers have affected the environment through nitrate poisoning and extermination of beneficial micro flora and micro fauna by adversely affecting the physical and chemical structure of the soil. It has been observed that the concentration of chemicals in ground water has reached levels, which are hazardous to human, and livestock population. It has now become an imperative to restore the soil with a beneficial microbe population by using Bio Fertilizers.
Bio Fertilizers contain live cells of specific isolated strains of bacteria and fungi which are formulated in suitable carriers. These microbes upon application to soil under suitable conditions secrete metabolites and enzymes which make the deficient element available to the plant in an assumable form. Other microbes - Mobilize / Solubilize the element in soil and make it available to the plant.
These beneficial microorganisms work incognito to maintain the ecological balance by active participation in carbon, nitrogen, sulphur and phosphorous cycles in nature.
Navaratnaa manufactures the following Bio Fertlizers :
1. Nitrogen Fixing Bacteria
2. Phosphorus Solubilizing Bacteria
3. Potassium Mobilizing Bacteria
4. Ferrous Mobilizing Bacteria
5. Zinc Mobilizing Bacteria
6. Sulphur Mobilizing Bacteria
7. Manganese Solubilizing Microbe
8. Vesicular Arbuscular Mycorrhiza ( VAM)
Bio Fertilizers are a suitable supplement to chemical fertilizers to meet the integrated nutrient demand of the crops. Application of Biofertilizers results in increased mineral and water uptake, root development, Vegetative growth and yield of a good quality. They are eco friendly, non toxic, easy to use, economical bio solutions that improve soil health and crop productivity.
