According to the survey, currently more than 31 million hectares of farmland are under organic management worldwide, a gain of around five million hectares in a single year. A major increase of organic land has taken place in China, where nearly three million hectares of pastoral land were recently certified. After the introduction of chemical fertilizers in the last century,
farmers were happy of getting increased yield in agriculture
in the beginning. But slowly chemical fertilizers started displaying
their ill-effects such as leaching out, and polluting water basins,
destroying micro-organisms and friendly insects, making the crop
more susceptible to the attack of diseases, reducing the soil
fertility and thus causing irreparable damage to the overall
system. A number of intellectuals throughout the world started working
on the alternatives and found that biofertilizers can help
in increasing the yield without causing the damage associated
with chemical fertilizers.
200 g of nitrogenous biofertilizer and 200 g of Phosphotika are suspended in 300-400 ml of water and mixed thoroughly. Ten kg seeds are treated with this paste and dried in shade. The treated seeds have to be sown as soon as possible. For rice crop, a bed is made in the field and filled with water. Recommended biofertilizers are mixed in this water and the roots of seedlings are dipped for 8-10 hrs. 4 kg each of the recommended biofertilizers are mixed in 200 kg of compost and kept overnight. This mixture is incorporated in the soil at the time of sowing or planting. http://www.ikisan.com/links/up_riceBiofertilizers.shtml#top http://www.entireindia.com/YellowPg/YpCatList.asp?s=1159&cnm=Biofertilizers http://www.glsbiotech.com/products.htm#biofertilizers http://www.us.erc.org/greenchannel/gc7/innovativebiotechnologicalproductsforagriculture.php builders , | ||||||
