Prime Minister Narendra Modi on February 19 asked Niti Aayog and state governments to set up expert committees on agriculture to work out a common minimum programme for providing a boost to the sector. "To boost agriculture...all states and Government of India together will identify the common minimum programme for nation-wide implementation," he said. Launching the Soil Health Card scheme, Modi said that he has directed Niti Aayog and the states to set up high powered expert committees on the agriculture sector. "Till now, it used to be a top to bottom approach. Now, we are going to take bottom to top approach. First, the state will prepare a policy on agriculture, later the Centre will come up with a policy after discussing with states. This initiative has already started," he said. The farmers need to do away with traditional farming techniques and adopt scientific methods of agriculture to raise crop yields, he said, adding that the farming strategy should depend upon the quality of soil. Highlighting the importance of soil testing, Modi said that farmers must focus on the health of soil in agricultural areas across the country, to boost productivity and bring about increased prosperity. Modi said farmers can save a minimum of Rs 50,000 if they take decisions based on scientific testing of soil. Calling for soil testing to be made a regular feature, the Prime Minister said a new class of entrepreneurs could set up soil testing labs even in small towns. The centrally-sponsored scheme aims to provide soil health cards to over 14 crore farmers in the next three years to promote balanced use of fertilisers.
