Satellite Data Plus Conservation Equals Better Crop Yields

Combining remote sensing technology with water and soil conservation techniques can help raise crop yields in South Asia, scientists have reported. Satellite data can help identify specific problems on farmlands such as moisture shortage, excessive soil wetness and flood occurrence. Using the data along with appropriate resource conserving technology (RCT) will increase productivity, a study team of researchers reported this month (8 September) in Applied Geography. The study team included researchers from the International Rice Research Institute (IRRI), Manila, International Maize and Wheat Improvement Centre, Banaras Hindu University, Jawaharlal Nehru University, Delhi, and Punjab state’s department of agriculture. Applied in the Balia district of northern Uttar Pradesh state, the method showed significant increase in annual per hectare incomes — US$ 63 by raising beds in saline soils, US$ 140 by introducing deep-water rice varieties, and US$ 147 through timely wheat planting.
