Field validation of Nutrient Expert for single season rice in China
Nutrient Expert Rice was developed to evaluate and validate fertilizer recommendation method based yield response and agronomic efficiency as compared with soil testing and farmer's practice
IPNI-2014-CHN-NESR
Nutrient Expert® (NE) field validation continued for single-season rice in 2017 through 10 on-farm experiments in Jilin and Heilongjiang Provinces of China. The objective was to compare the NE-based fertilizer recommendation method with traditional soil test-based fertilizer recommendations and farmers' practice (FP), in terms of rice grain yield and nutrient use efficiency. Each individual field site received a site-specific fertilizer application based on the NE tool and soil test results. Read more
