System of Rice Intensification has provided results of substantial increases in yield by 25 to 50 percent using less water than is commonly used for irrigated production. By achieving higher yields and greater profitability with fewer purchased inputs, SRI is showing that the input-dependence of modern agricultural practices is not necessarily the most productive or the most economic approach. This alternative system manages plants, soil, water and nutrients differently in ways that increase the abundance and diversity of the soil biota. Farmers are finding that they can get more output by reducing their external inputs, rather than by increasing them. SRI initially requires more effort while farmers gain knowledge, skill and confidence. This initial cost is offset by reduced requirements for seed, water, and costs of production.
