Nutrient Management Strategies for Yunnan

IPNI-1999-CHN-YN13

Background: Songmin and Qujin in Yunnan are the main agricultural bases where both value commercial cash crops and food crops grow. However, fertilization in Songmin and Qujin were mainly depended on farmer’s experiences in the past. The farmer’s experiences were limited by their farming knowledge and their education background. Most of the farmers do not really have the knowledge to properly manage their crop fields. Read more

Interpretive Summary

Nutrient Management Strategies for Grain and Tobacco Systems in Yunnan, 2007 This project was established to monitor the impact of different fertilizer treatments on crop yields under two typical farming systems in Yunnan (i. e. , rice-broad bean in Songmin County and wheat-tobacco or wheat-maize in Qunjing County). The goal was to track soil nutrient variability induced by fertilization and to develop rational fertilizer nutrient management systems.

Nutrient Management Strategies for Grain and Tobacco Systems in Yunnan, 2006 This project was initiated in 2001 to monitor the impact of different fertilizer treatments on crop yields in rice-broadbean and wheat-tobacco cropping systems. Songmin and Qujing counties were selected to track nutrient variability within typical farming regions in Yunnan, collect fertilizer use information, and gather field trial data in order to develop rational fertilizer nutrient management systems.

Nutrient Management Strategies for Grain and Tobacco Systems in Yunnan, 2005 Foodgrain production systems including rice, wheat, and broadbean continue to be the prominent staples in Yunnan, while tobacco production plays an important role in income generation for farmers and local governments.

Nutrient Management Strategies for Yunnan, 2004 Qujing and Songmin counties provide good examples of the regional grain/tobacco farming system and were selected to systematically track nutrient variability, collect fertilizer use information, and produce field trial data in order to develop a rational fertilizer nutrient management system. Initial soil tests were taken in 2001, while village maps of nutrient variability were formed in 2002/03.

Nutrient Management Strategies for Yunnan, 2003 Qujing County and Songmin County are representative of the grain/tobacco farming system. They were selected to track nutrient variability and collect fertilizer use information and field trial data, all of which will be used to develop a rational fertilizer nutrient management system. Soil deficiencies were determined by soil testing (2001) and village maps of nutrient variability were formed in 2002.

Nutrient Management Strategies for Yunnan, 2002. Initiated in 2000, this project’s objective is to track soil fertility variability and to collect information from field trials and fertilizer use surveys in a typical grain and grain-tobacco farming area in Yunnan. In 2001, the nutrient limiting factors to crop growth were determined through soil testing. In 2002, the village field map and nutrient variability maps were generated using geographic information system software.

Nutrient management strategies in Yunnan province, 2001 This monitored village study in Qujing and Songmin counties, which represent typical grain and grain-tobacco farming areas in Yunnan province, is tracking variability in soil fertility and providing information from field trials and fertilizer use surveys to populate the PPI/PPIC China Program Soil Fertility Information Database. The final objective is to develop a proper soil nutrient management system to support rational fertilization.

Nutrient management strategies project in Yunnan province, 1999 In Yunnan province, tea plants had very good response to balanced fertilizers in yield, quality and net income in three locations, which was even better in 2000 than in 1999. The tea yield increase over the K0 treatment was 1486 kg/ha (15. 2%) at Menghai, 3060 kg/ha (30. 0%) at Simao and 2989 kg/ha (42. 5%) at Eshan. The net income increase vs.
