26 Dec Residue Recycling in Crop Production
फसल उत्पादन में अवशेषों का पुनःचक्रण Residues are the by-products of crops plants and other vegetative products of plants are which are organic in nature and has vital importance for agricultural production. The monotonous use of inorganic fertilizers devoid of balanced NPK and micronutrients has resulted in decreasing soil organic carbon (SOC) and fatigued crop production. Soil organic matter (SOM) mostly obtained from organic residues facilitates the aggregation and structural stability of soils and responsible for air-water relationship for root growth and protection of soil from wind and water erosion. The composting, in-situ incorporation or retention as stubble mulch are the common methods of residue management. Residues in general are C-rich materials but contain sufficient amounts of essential plant nutrients. Therefore, their recycling in crop production is an important means of meeting nutrient requirements of the crop plants. Hence, residue application is useful to enhance crop productivity, soil health and profitability both in irrigated and rainfed ecosystems. Scope of Crop residues recycling Indian agriculture is entering a new phase. With time the growing concerns for sustainable agriculture have shown a positive response with the advance of conservation agriculture and it has come as a new paradigm to achieve goals of sustained agricultural production. The residue recycling is more common in conservation agriculture.About 675 Mt crop...
