Managing soil nutrients
Soil erosion caused by over-grazing, deforestation and intensive unsustainable agricultural practices has lead to loss of soil fertility and valuable soil nutrients. Important nutrients in the soil like phosphorous, Potessium and Nitrogen, secondary nutrients like Calcium, Magnesium, Sulfur, and micro nutrients like Iron, Managanese, Copper, Zinc, Chloride, Molybdenum, Boron, Selenium are lost from the soil. These nutrient lost have an impact on productivity as well as the nutritional value of the crop. Thus management of soil nutrient is an important factor and other then the above-discussed method to reduce soil erosion and run-off, the application of improvement-based method to improve the present soil quality will increase soil fertility and productivity. These methods are:
