Soil Health Awareness: Soil Science at Doorsteps of the Farmers uri icon

abstract

  • Rainfed semi arid tropics (SAT) are hot spots of poverty and malnutrition, andpopulation explosion is further aggravating the problem. Out of 852 million hungry andmalnutritioned poor worldwide, 221 million are in India. Attaining food and nutritionalsecurity for these regions is a big challenge particularly in view of climate change whichis expected to hit hard again these areas. Poor soil health in addition to water scarcity,largely due to mining of soil nutrients and inappropriate nutrient management optionsadopted by the farmers, is a major constraint leading to sub optimal crop yields (1-1.5t ha?') and lower economic returns inspite of existing potential (2.5-7.0 t ha?' ). Poor soilhealth is also responsible to low water use efficiency due to limiting nutrients andexhausted C. Now, there exists a vicious poverty-food security-land degradation nexusin which a farmer is trapped
