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 2016 through 10 on-farm experiments in Jilin and Heilongjiang Provinces of China. The objective was to compare the NE-based fertilizer recommendation method with the traditional soil test-based fertilizer recommendation and farmer’s practice (FP) in terms of rice grain yield and nutrient use efficiency. Each individual field site had a site-specific fertilizer rate based on the NE tool and soil test results. Read more

Interpretive Summary

Nutrient Expert® (NE) field validation continued for single-season rice in 2016 through 10 on-farm experiments in Jilin and Heilongjiang Provinces of China. The objective was to compare the NE-based fertilizer recommendation method with the traditional soil test-based fertilizer recommendation and farmer’s practice (FP) in terms of rice grain yield and nutrient use efficiency. Each individual field site had a site-specific fertilizer rate based on the NE tool and soil test results.

Validation of Nutrient Expert® (NE) for single-season rice continued in 2015 through 10 field experiments in both Heilongjiang and Jilin. The objective was to test the NE-based fertilizer recommendation method against soil test-based recommendations and farmer’s practice (FP). Each individual site had a site-specific rate applied.

The Nutrient Expert(R) (NE) for rice decision support system was first validated in single season rice in Heilongjiang and Jilin in 2014. The objective was to test the NE-based fertilizer recommendation method against soil test-based recommendations and farmer’s practice (FP). Each individual site had a site-specific rate applied.
