WHAT ARE BIO FERTILIZERS ? Bio-fertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil promotes growth by increasing the supply or availability of primary nutrients to the host plant.
Biological Fixation of N 2 Bio-fertilizers add nutrients through the natural processes of Nitrogen fixation, solubalizing phosphorus, and stimulating plant growth through the synthesis of growth promoting substances.
A FEW EXAMPLES … Rhizobium-Bio Fertilizer Azotobactor-Bio Fertilizer PSB-Bio Fertilizer Bio Neem Gold – Bio pesticide Trichoderma Viride-Bio Fungicide
Bio-fertilizers can reduce the use of chemical fertilizers and pesticides and also have high productivity. Healthy plants can be grown while enhancing the sustainability (to maintain ecological balance) and the health of soil. Bio-fertilizers are eco friendly and pose no danger to the environment. They are low cost inputs, lead to soil enrichment and are compatible with long term sustainability. Helps cleanse the plant from precipitated chemical fertilizer.
TYPES OF BIO-FERTILIZERS Nitrogen Fixing Bacteria Phosphate-Solubilizing Bacteria
Nitrogen Fixing Bacteria Nitrogen-Fixing Microorganism are introduced to the soil to improve the nitrogen supply available to the plants. Examples Uses • • • used for legumes • wheat, corn, mustard, cotton, potato, and other vegetables • for specific use on sugarcane Rhizobium Azotobacter Acetobacter Azospirillum
HOW DO BIO-FERTILIZERS Bacteria digest large biopolymers to smaller monomers WORK? which plants can absorb easily. 1) Proteins - Amino Acids 2) Carbohydrates & Fibers - Sugars 3) Fats - Fatty Acids Role of Soil Bacteria • Soil-bacteria release biochemical which accelerate the plant growth. • They scavenge phosphate from soil layers. • They increase the availability of nutrients. Phosphate Rhizobium Nitro-fixing Bacteria
MAKING OF FARM YARD MANURE Raw Materials: Cow dung, cow urine, waste straw and dairy wastes Preparation: v. Cow dung is collected in a pit and is allowed to decompose over a period of time. v Every month this manure is applied to the plants or the field to enrich the soil. v The slurry that comes out after gobar gas generation is highly composted and extremely rich.
Why FARM YARD MANURE ? ØImproves soil fertility. ØA larger portion of N 2 is made available as and when the FYM decomposes. ØAvailability of Potassium and Phosphorus from FYM is similar to
ITS OUR APPEAL TO THE PEOPLE TO ENCOURAGE THE USE OF BIO-FERTILISERS IMPROVE THE FERTILITY OF LAND RATHER THAN KILLING IT WITH CHEMICALS.
