Nutrient Management Strategies for Guangxi

IPNI-2002-CHN-GX11

Impact of Residual Nutrients on Citrus and Food Crop Fertilization in Guangxi, 2007 Laibin County and Fushui County were selected as long-term monitored village sites in 2002. In past years, soil nutrient limitations were determined and verified, and soil nutrient variability maps were developed. In 2005, the study tested the influence of balanced fertilization (BF) on crop yields. Read more

Interpretive Summary

Impact of Residual Nutrients on Citrus and Food Crop Fertilization in Guangxi, 2007 Laibin County and Fushui County were selected as long-term monitored village sites in 2002. In past years, soil nutrient limitations were determined and verified, and soil nutrient variability maps were developed. In 2005, the study tested the influence of balanced fertilization (BF) on crop yields.

Impact of Residual Nutrients on Citrus and Food Crop Fertilization in Guangxi, 2006 Laibin and Fushui counties were selected as long-term monitored village sites in 2002. In past years, soil nutrient limitations were determined and verified, and soil nutrient variability maps were developed. In 2005, the study tested the influence of balanced fertilization (BF) on crop yields.

Impact of Residual Nutrients on Citrus and Food Crop Fertilization in Guangxi, 2005 Laibin and Fushui counties were selected as long-term monitored village sites in 2002. In past years, soil nutrient limitations were determined and verified, and soil nutrient variability maps were developed. In 2005, the project continued its study of the influence of balanced fertilization (BF) on crop yields.

Nutrient Management Strategies for Guangxi, 2004 Laibin and Fushui counties continued as long-term monitored village sites. Soil nutrient limitations identified by initial soil testing in 2002 continue to be verified by field trials. This information will be used to develop reliable recommendations capable of sustaining crop yield and quality. Peanut crops were deficient in nitrogen (N), phosphorus (P), potassium (K), and boron (B).

Nutrient Management Strategies for Guangxi, 2003 Laibin County and Fushui County are long-term monitored village sites. Nutrient use and soil fertility data will be evaluated, in combination with information from field trials to developing site-specific soil fertility management zones. Soil testing was used to develop soil nutrient variability maps in 2002 and nutrient limitations are being verified by fixed-site field trials.

Nutrient Management Strategies for Guangxi, 2002 . Initiated in 2001, the purpose of this study is to track soil variability between and within villages and among village fields. These data, combined with other information from field trials and fertilizer use surveys, will be used to improve fertilizer use for high yield, high benefit crop production. Soil testing was conducted during 2001 and soil nutrient variability maps were developed in 2002 using geographic information system software.
