09 Oct Role of Liquid Organic Manures in Soil Nourishment
मृदा पोषण में तरल जैविक खाद की भूमिका Manures are organic materials with plant nutrients in small concentrations. Organic manures are the main source of replenishing soil fertility. Organic farming is an internationally regulated legally enforced and standardized alternative paradigm relies on ecological processes, biodiversity for sustaining the health of soil. Solid organic fertilizer, cattle manure and green manure are the most nutritive organic fertilizers with an average nitrogen (N) content of 1.5%. Now a days Liquid Organic Manure has largely remained in background of bio-dynamic farming. The plant can absorb nutrients about 20 times fast through the leaves than applied through the soil. Therefore, liquid manures are helpful to overcome temporary nutrient shortages. In organic farming it is mainly used to stimulate growth during the season when nutrient uptake through the roots is hindered. Liquid manure is from farmyard manure or plant material (plant teas or slurry). Nutrient rich material is soaked in water for several days or weeks to undergo fermentation. Frequent stirring encourages microbial activity in liquid manures. The resulting liquid can either be used as a foliar fertilizer or applied to the soil. Types of Liquid Organic Manures 1. Panchagavya In India traditional liquid fertilizer called Panchagavya, a manure tea made by fermenting cow dung, cow urine, milk, curd and ghee in water have a modest NPK...
