Interpretive Summary

Fertilizer Placement Promotes Banana Yields in Guangdong, 2008 The past 2 years of study have revealed details on the growth of the banana rooting system and has shed new light on improved fertilizer placement methods.

Nutrient Management Strategies for Banana in Guangdong, 2007 Banana is one of the most lucrative crops in southern China and is widely produced in the provinces of Guangdong, Guangxi, and Hannan where weather favors its growth. Due to its extremely high yield, fertilizer rates of K and N are particularly high and its nutrient uptake usually surpasses any other crop.

Nutrient Management Strategies for Banana in Guangdong, 2006 This study was initiated in 2002 at Sanshui and Zhongshan cities to track soil nutrient variability between and within fields, and to develop a sustainable soil fertility management plan for the region. Improved fertilization rates have consistently increased crop yields and quality for the past 5 years.

Nutrient Management Strategies for Banana in Guangdong, 2005 This study was initiated in 2002 at Sanshui and Zhongshan to track soil nutrient variability between and within fields, and to develop a sustainable soil fertility management plan for the region. Improved fertilization rates have consistently increased crop yields and quality for the past 4 years.

Nutrient Management Strategies for Guangdong, 2004 This study was initiated in 2002 at Sanshui and Zhongshan cities to track soil nutrient variability between and within fields and to develop a regional soil fertility management plan. Nutrient limitations were determined through soil analyses. Digital nutrient deficiency maps were developed in 2002. Litchi field trials were established in 2003 and 2004 to verify soil testing results.

Nutrient Management Strategies for Guangdong, 2003 This study was initiated in 2002 at Sanshui City and Zhongshan City to track soil nutrient variability between and within fields and to develop site-specific soil fertility management zones. Soil nutrient limitations were determined as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and sulfur (S) through soil analyses and digital maps of these deficiencies were developed.

Nutrient Management Strategies for Guangdong, 2002 . Initiated in 2002, this project is tracking 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 applied to improve fertilizer use for high yield, high benefit crop production. The locations selected represent commercial vegetable and banana plantation regions in Guangdong.
