Geographical area of India 3287 lakh ha Net cultivated area : 1420 lakh ha Irrigated area : 570 lakh ha Rainfed area : 850 lakh ha Low productivity and low input usage are two major issues confronting rainfed farming. Productivity per unit of land Productivity per unit of water are important for optimum production.

ACID SOILS
SALINE SOILS
ALKALINE SOILS
RECLAMATION OF SALINE SOILS 1.Deep ploughing 2. Sanding 3.Adding gypsum 4.Adding sulfur 5.Adding organic matter Causes : Low rainfall, high evaporation rate, poor drainage, irrigation with saline water RECLAMATION OF ALKALINE SOILS Application of gypsum, leaching, green manuring, straw mulching Causes : presence of carbonates of ca, mg and na RECLAMATION OF ACID SOILS: Adding ground limestone (calcium carbonate) Causes : High rainfall

WATER Blue water is the source of supply. It is equivalent to the natural water resources (surface and groundwater runoff). Green water is the rainwater directly used and evaporated by non-irrigated agriculture, pastures and forests

WATERSHED A geohydrological unit draining to a common point by a system of drains. It is topographically delineated area draining into a single channel. It is considered as a biological, physical, economic and social system It is environmental tool for taking up development initiatives It is a logical unit for planning optimal development of its soil, water and biomass resources.
