With S.R.I, farmers use fewer seeds and transplant them earlier than usual. Leaving more room between plants lets the roots and leaves spread more. Farmers also use less water. They keep the fields moist but do not continuously flood them. The use of chemical fertilizer is also reduced or even eliminated.
Norman Uphoff is a big supporter of the System of Rice Intensification. He was a professor of government and international agriculture at Cornell University in Ithaca, New York. He retired but still works from an office there to bring attention to the system.
