Assessment of the Impact of Targeted Use of Fertilizer - Irrigated rice in Asia

In 2010, rice (Oryza sativa L.) was grown on 162 million ha, with 91% produced in Asia. It is the main staple food crop in Asia, providing more than 50% of calories in some countries. Worldwide, about 93 million ha of irrigated lowland rice (57% of the rice production area) provides 75% of global rice production. In Asia, rice is grown on 30-83% of all irrigated land.

Rice provides 19% of global human per capita energy and 13% of per capita protein. But to provide for the future needs of the growing world population, rice production needs to grow annually by 1.2-1.5% over the coming decade (GRISP, 2013).

This publication provides an assessment of the impact of the targeted use of fertilizer using Site Specific Nutrient Management (SSNM), looking at the impact on farmers’ income, soil health, plant health, and the environment.

The publication can be downloaded from the IPI website.
