Review on vermicompost, poultry manure, farmyard manure, biogas digest, biochar, urban compost and biofertilizers as potential alternate nutrient sourcesf for sustainable agriculture
Author(s): P Venkata Subbaiah
Abstract: Organic sources of nutrients like vermicompost, poultry manure, farmyard manure, biogas digest, biochar, urban compost are rich sources of macro & micro nutrients, vitamins and other growth promoting substances. The activity of soil microflora increases tremendously with the application of organic manures to soil. Several investigations reveal that organic manures can substitute 25-30 per cent of the recommended doses of inorganic fertilizers in crop production. The integrated use of all available sources of nutrients increases the soil health, yield and quality of crop produce. Use of organic manures as nutrient sources with possible substitutions through INM decreases the cost of inorganic fertilizers. These organic manures are also playing greater role in organic farming. Organic manures improve soil quality by increasing the soil carbon content. Integrated use of these organic source of nutrients along with inorganic sources increases the crop yields 15-30 per cent.
