Abstract
The green revolution, white and blue gave us food security. The high yield varieties and new technologies were webbed with chemical farming. Even today we have critical gaps in the productivity of foodgrains between technology with farms and farming practices. The chemical farming has led to soil degradation, water pollution, soil erosion and salinity. Meanwhile, we are faced with land degradation in 173 million hectares or about 53% of the area. Each year we lose 5000 million tons of topsoil with NPK losses of 5-8 million tonnes per year.
In Mahrastra according to a survey that the black soil depth of 60 cm in 1910 which has since been reduced. Over 18% of it became a flat. Reduced soil depth is now due to low productivity in the runoff of soil and drought conditions. Therefore, to avoid these negative effects, we have solid information and communication methods for binding soil mapping, data of annual rainfall, rainfall and climate forecasts for farmers (Wani, 2005).
The conservation and proper use must have sufficient knowledge to be produced by the advanced satellite system and was able to count back through communication mechanism. Thus, to increase agricultural production, communication tools should be used. » Read more: Capacity Building and E.extension for Enhancing Agriculture Productivity in India
