More profit through efficient use of nutrients

Rice requires an adequate supply of nutrients to achieve the high yields necessary to feed growing populations. Many of these nutrients come from soil, but high yields still require supplemental nutrients from fertilizer.

Fertilizer, after labor, is the second-largest input cost for irrigated rice; rice receives one third of all fertilizer used in Asia. The Productivity and Sustainability workgroup strives to ensure cost-effective and ecologically and socially acceptable rice production through nutrient management tailored to the site- and season-specific needs of rice.

Feeding crop needs

Site-specific nutrient management (SSNM) enables rice farmers to optimally supply their crop with essential nutrients. With SSNM, plant-essential nutrients are supplied as and when required to ensure the ‘feeding’ of the rice crop to optimally meet its nutrient needs. For more information visit the SSNM website

Site-specific nutrient management helps
rice farmers and the environment

Scientists have found a way for rice farmers to increase their profit and produce more food by optimally applying essential nutrients to their crops. Rice requires essential nutrients such as nitrogen, phosphorus, and potassium that are typically not present in the soil in sufficient amounts to meet crop needs. The approach developed by scientists for optimal application of supplemental nutrients enables farmers to achieve rice yields well matched to their local climatic and crop-growing conditions.
