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...

The soils having pH 7 are neutral in reaction and those below or above 7 are acidic or alkaline respectively. In neutral soils, satisfactory plant growth can be expected, provided all other agronomic practices are followed properly. But neither acid soils nor saline soils are suitable for most of the crops except a few tolerant ones. Acidity or salinity acts as a limiting factor in crop production. When the concentration of some elements which are naturally acidic in reaction, goes too high...
