रासायनि‍क रूप से वि‍कृत भारतीय मृदाओं का प्रबन्‍धन।  Chemical deterioration of soils is a type of soil degradation that involves loss of nutrients or organic matter, salinity, acidification, soil pollution and fertility decline. The removal of nutrients reduces the capacity of soils to support plant growth and crop production and causes acidification. In arid and semi-arid areas problems can arise due to accumulation of salts, which impedes the entry of water in plant roots. Chemical deterioration of soils is often also due to agricultural over exploitation, relying solely on replenishing nutrient losses through harvesting by artificial chemical fertilizers. Indiscriminate irrigation for getting higher yield has led to water logging; nutrient losses and increased salinity of lands threatened the sustainability of crop yields. The increasing salinization of...

टिकाऊ फसल उत्पादन में मृदा भौति‍क दबाव और उनके प्रबंधन के विकल्प Enhanced soil productivity and assured sustainability are the two major concerns to feed the increasing population of the modernized world. Scientific planning and management practices for further enhancement and sustaining of the productive potential of soils, however, require a proper understanding of the factors limiting its productivity.  About 1704.68 lakh ha of land areas of our country at present is affected by various soil problems. A number of soil physical constraints result into unfavorable soil environment for nutrient availability and utilization by crops. The physical fertility describes state of soil in respect of flow of water and air, thermal regimes and...
