Description
Then one-sided development in fertilizing of soils with only main nutrients, the gradual loss of micronutrients through weathering and leaching, the decreasing use of organic manures and increasing use of high analysis fertilizers (which are relatively pure and do not contain trace element impurities) is contributing towards accelerating exhaustion of available supply of trace elements. Soil texture affects how well nutrients and water are retained in the soil. Clays and organic soils hold nutrients and water much better than sandy soils. An ideal soil contains equivalent portions of sand, silt, clay, and organic matter. Sometimes, the nutrients that plants need occur naturally in the soil. Othertimes, they must be added to the soil as lime or fertilizer. The book also undertakes a look at the challenges associated with the heavy use of fertilisers in crops.
