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
Слайды и текст этой презентации
Слайд 3 Bio-fertilizers add nutrients through the natural processes of Nitrogen
fixation, solubalizing phosphorus, and stimulating plant growth through the synthesis
of growth promoting substances.Biological Fixation of N2
Слайд 7Nitrogen Fixing Bacteria
Nitrogen-Fixing Microorganism are introduced to the soil to
improve the nitrogen supply available to the plants.
Слайд 8HOW DO BIO-FERTILIZERS WORK?
Bacteria digest large biopolymers to smaller monomers
which plants can absorb easily. 1) Proteins - Amino Acids 2) Carbohydrates
& Fibers - Sugars 3) Fats - Fatty AcidsRole 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
Слайд 9MAKING OF FARM YARD MANURE
Raw Materials: Cow dung, cow urine,
waste straw and dairy wastes
Preparation:
Cow dung is collected in
a pit and is allowed to decompose over a period of time. Every month this manure is applied to the plants or the field to enrich the soil.
The slurry that comes out after gobar gas generation is highly composted and extremely rich.
Слайд 11ITS OUR APPEAL TO THE PEOPLE TO ENCOURAGE THE USE
OF BIO-FERTILISERS IMPROVE THE FERTILITY OF LAND RATHER THAN KILLING
IT WITH CHEMICALS.
