DESCRIPTION OF COURSES
SSAC 603 NUTRIENTS IN SOILS AND PLANTS (3L+0P) I
To teach latest developments in soil-plant interactions/ relationships with respect to nutrient management
Essential nutrients – historical perspective; nutrient status of the world and Indian soils; nutrient content in relation to stages of crop growth and their uptake by crops and cropping systems.
Carbon - a nutrient central to soil fertility; carbon cycle in nature, stocks, pools and fluxes; greenhouse effect and climate change; carbon sequestration vis-à-vis sustenance of soil quality and crop productivity.
Recent advances in bioavailability, transformation and dynamics of major- and micro-nutrients in soils.
Growth and the factors affecting it; current approaches in soil fertility evaluation: critical nutrient concentration - concept and determination (graphical and statistical procedures); diagnosis and recommendation integrated system (DRIS).
Nutrient interactions – concepts, chemical and biochemical basis, and models for study; nutrient interactions in soil-plant continuum for maximization of the productivity of crops and cropping systems; water – nutrient interactions under excess and scarce water supply situations; fertigation – an example of water-nutrient synergy.
Nutrient management in water-logged soils and under organic farming and precision farming.
Nutrients and crop quality; micronutrients and human health - essential micronutrients list and their critical levels for human health; biofortification – concept, approaches and implications.
