Interpretive Summary

Effect of Cash Crop Hedgerows and Land Use Patterns on Soil Conservation of Sloping Lands in Guizhou, 2008 This ongoing study, initiated in 2004, continues to monitor various land use patterns, with or without established hedgerow crops, in order to select and extend optimal land use practices for sloping lands in Guizhou.

Effect of Different Cash Crop Hedgerows and Land Use Patterns on Soil Conservation of Sloping Lands in Guizhou, 2006 This study was initiated in 2004 to monitor and evaluate various patterns of land use with or without established hedgerows in order to select and extend optimal land use practices for sloping lands in the region.

Effect of Different Cash Crop Hedgerows and Land Use Patterns on Soil Conservation of Sloping Lands in Guizhou, 2005 The purpose of the study is to monitor and evaluate various patterns of established cash crop hedgerows in Guizhou in order to select and extend optimal land use practices for sloping lands in the region. Field experiments were upgraded to 10 treatments based on results from 2004.

Nutrient Management Strategies for Sloping Lands in Guizhou, 2004 Previously supported research finds alley cropping to be an effective means of reducing soil erosion, and specifically, soil potassium (K) loss. both major agronomic concerns for developing sustainable crop production technologies on sloping lands. The integration of balanced fertilization (BF) substantially improves crop yields and further reduces soil erosion.

Nutrient Management Strategies for Sloping Lands in Guizhou, 2003 The influence of alley cropping on soil erosion, and specifically, soil potassium (K) loss is a major agronomic concern in developing sustainable crop production technologies. Our tactic of integrating a balanced fertilization (BF) program has shown substantial promise for these highly erosive landscapes of southwest China.

Nutrient Management Strategies for Sloping Lands in Southwest China, 2002 . This project will quantitatively evaluate the effectiveness of alley cropping on reduction of soil and potassium (K) loss and develop a balanced fertilizer program specifically for regions with erosive soils and landscapes in Guizhou as well as southwest China. Daylily plus chinese prickly ash (D+C) and Polygonum cymosum trev. plus plum (P+P) were selected as two patterns of hedgerow crops.

Nutrient management strategies sloping lands in Guizhou province, 2001 The project aims to quantify the effectiveness of alley-cropping in reducing soil and potassium (K) loss and to develop a balanced fertilization (BF) program for the erosive soils and landscapes in southwest China. Daylily + Chinese prickly ash (D+C) and Polygonum cymosum trev. + pear tree (P+P) were selected as the two patterns of hedgerow crops, and an engineered terrace (ET) was used as comparison treatment.

Nutrient management strategies sloping lands project in Guizhou province, 1999 The objective of this project is to quantitatively evaluate the effectiveness of the alley cropping on reduction of soil and K loss and to develop a balanced fertilizer program specifically for the regions with erosive soils and landscapes in the southwest China focusing on Guizhou province.
