Nutrient Management and Balanced Fertilization on Major Crops in Jilin Province

The project has been focusing on Nutrient Expert based fertilizer recommendation since 2011

IPNI-2006-CHN-JL7

This study was conducted to validate the long-term effect of a Nutrient Expert(R) (NE)-based fertilizer recommendation for spring maize in farmer fields. Results for the NE were compared against farmer fertilization practices (FP). For this project, starting in 2012, 10 on-farm experiments were successively conducted in three different counties in Gongzhuling, Jilin. Read more

Interpretive Summary

This study was conducted to validate the long-term effect of a Nutrient Expert(R) (NE)-based fertilizer recommendation for spring maize in farmer fields. Results for the NE were compared against farmer fertilization practices (FP). For this project, starting in 2012, 10 on-farm experiments were successively conducted in three different counties in Gongzhuling, Jilin.

This study was conducted to validate Nutrient Expert® (NE)-based fertilizer recommendation for spring maize in farmer fields and compare them with farmer fertilizer practice (FFP). For this project, 15 on-farm experiments were conducted in three different counties in Gongzhuling, Jilin Province. Nutrient Expert®-based fertilizer recommendation plots received an average of 156-82-94 kg N-P2O5-K2O/ha, while FFP plots received 243-119-94 kg N-P2O5-K2O/ha, respectively.

Nutrient Expert®-based Fertilizer Recommendations for Spring Maize in Jilin, 2012. This study was conducted to validate Nutrient Expert® (NE)-based fertilizer recommendations for spring maize in farmer fields and compare them with farmer fertilizer practice (FFP). Twenty-six (26) on-farm experiments were conducted in four different villages in Gongzhuling city, Jilin province.

Nutrient Expert-based Fertilizer Recommendation for Spring Maize in Jilin, 2011. This study was conducted to validate Nutrient Expert (NE)-based fertilizer recommendations for spring maize in farmer fields and compare them with farmer fertilizer practice (FFP). For this, thirty (30) on-farm experiments were conducted in five different villages in Gongzhuling city, Jilin province.

Effect of Long-Term Potassium Application on Maize Yield (Jilin), 2010 This long-term fixed field experiment has been conducted in Liufangzi County of Jilin Province since 1993. In this experiment, N and P2O5 rates were consistently applied at 225 kg/ha and 113 kg/ha, respectively, while K2O rate was varied between 0, 113, and 225 kg/ha. Results showed that 113 kg K2O/ha increased yield by 1,637 kg/ha, or 17% above the 0 K check. Net income reached USD 307/ha at the intermediate K rate.

A Macronutrient Rate Study for Maize Production in Jilin, 2009 A total of 18 field experiments were designed for 2009 to determine the proper rates for N, P, and K fertilizers for high yield maize production in selected locations within the “spring maize belt” in Jilin Province. Results indicated that N rates for maximum economic yield ranged between 63 to 188 kg N/ha, appropriate P rates ranged between 51 to 62 kg P2O5/ha, and K rates ranged between 23 to 72 kg K2O/ha.

Nutrient Management and Balanced Fertilization on Main Crops in Jilin, 2009 Field experiments on N, P, and K rates for high yield maize were conducted in selected locations within the "maize belt" in Jilin Province in 2008. Results indicated that, with available soil N between 107 to 202 mg/kg, the N rates for maximum economic yield ranged between 93 to 173 kg N/ha, resulting in maize yields between 9,600 to 12,280 kg/ha.

Optimizing Fertilization According to Cultivar Response to Fertilizer, 2007 A field experiment at Gongzhuling determined the yield response equations for the corn variety Pioneer 335 to help optimize N, P, and K rates. Optimum rates for maximum profit were calculated to be 147 kg N, 65 kg P2O5, and 85 kg K2O/ha. Optimal rates for a maximum yield were 160 kg N, 78 kg P2O5, and 91 kg K2O/ha. The corresponding agronomic efficiency was 19. 7-11. 7-22. 4 kg/kg N-P2O5-K2O under maximum profit and 18.

Optimizing Fertilization According to Cultivar Affinity to Fertilizer, 2006 Research activities in 2006 continued with balanced fertilization studies on corn. Also, the concept of cultivar-specific fertilization was studied with a group of corn cultivars. The 14-year fixed-site field experiment determined that 113 and 225 kg K2O/ha could respectively produce 10% and 5. 9% more yield, and US$125/ha and US$5/ha more profit, over the K omission check which yielded 10.
