Improving Topsoil Quality and Crop Productivity with Sloping Land Management Using Balanced Fertilization and Cash Crop Hedgerows in Yunnan, 2009 In its final year. this trial continues to monitor the effects of balanced fertilization, contour cultivation, and hedgerow crops as soil conservation measures for the sloping lands of Yunnan. Soil erosion was highest in the farmers’ practice (FP) plots, measured at 241 m3/ha in water run-off and 5. 3 t/ha in soil loss. Read more

Improving Topsoil Quality and Crop Productivity with Sloping Land Management Using Balanced Fertilization and Cash Crop Hedgerows in Yunnan, 2009 In its final year. this trial continues to monitor the effects of balanced fertilization, contour cultivation, and hedgerow crops as soil conservation measures for the sloping lands of Yunnan. Soil erosion was highest in the farmers’ practice (FP) plots, measured at 241 m3/ha in water run-off and 5. 3 t/ha in soil loss.

Improving Topsoil Quality and Crop Productivity with Sloping Land Management Using Balanced Fertilization and Cash Crop Hedgerows in Yunnan, 2008 This trial continues to monitor the effect of balanced fertilization, contour cultivation, and hedgerow crops as soil conservation measures. In 2007/08, the objective was to determine the effect of different treatments on field slope changes.

Sloping Land Management using Balanced Fertilization and Cash Crop Hedgerows in Yunnan, 2007 This is an on-going trial aimed at monitoring the effect of balanced fertilization (BF) in combination with contour cultivation and hedgerow crops as soil conservation measures against the traditional farmer practice (FP).

Sloping Land Management Using Balanced Fertilization and Cash Crop Hedgerows in Yunnan, 2006 In 2004 and 2005, this sloping lands study focused on monitoring soil conservation, soil properties, crop yields, and farmers’ income as affected by the combined effect of balanced fertilization (BF) plus alley cropping using cash crop hedgerows.

Sloping Land Management Using Balanced Fertilization and Cash Crop Hedgerows in Yunnan, 2005 In 2005, this sloping lands study continued to monitor soil conservation, soil properties, crop yields, and farmers’ income resulting from the combined effect of balanced fertilization (BF) plus alley cropping using cash crop hedgerows.

Sloping Land Management on Sustainable Agriculture in Yunnan, 2004 The nucleus of this sloping land management technology is the combination of balanced fertilization with alley cropping using different hedgerow cash crops. This technique is capable of achieving good profits for farmers and has been proven an effective means of protecting these landscapes from soil erosion and water losses.

Fertilizer Use on Different Upland Cropping Systems for Soil Conservation in Yunnan, 2003 Balanced fertilization (BF) with nitrogen (N), phosphorus (P), and potassium (K) plus alley cropping, a system using hedgerow cash crops, is a profitable and effective new alternative to engineered terraces. This project introduced the technology, by transfer and subsequent adaptation of the Sichuan model, to erosion prone regions (Xiangyun and Fuming counties) in Yunnan.

Fertilizer Use on Different Upland Cropping Systems for Soil Conservation in Yunnan Province, 2002 . Compared to engineered terraces (ET), the combined application of balanced fertilization with alley cropping (BF/BB) using different hedgerow cash crops is a profitable approach to combating soil and water loss in Sichuan Province. This new technique is now being adapted and transferred to other parts of China.

Fertilizer use on different upland cropping systems for soil conservation in Yunnan province, 2001. The practice of alley-cropping is a profitable and effective new alternative to engineered terraces if it employs both a variety of hedgerow cash crops and balanced fertilization. This project is part of an effort to spread the adoption of this practice into regions like Yunnan Province, which is seriously affected by soil erosion problems.

Fertilizer use on different upland cropping systems for soil conservation in Yunnan province, 2000 Balanced fertilization plus alley cropping with different hedgerow cash crops is a profitable and effective new approach to combat soil erosion and water losses in Sichuan province in southwest China when compared to engineered terraces. This new technique is now being transferred to other parts of China.

Fertilizer use on different upland cropping systems for soil conservation in Yunnan province, 1999 Soil and water losses are serious problems associated with the southwest province of Yunnan. Although terraces have been engineered and adopted in some areas of the province, the practice requires a high initial investment and the risk of landslides is high within the first two years of establishment.

Fertilizer use on different upland cropping systems for soil conservation in Yunnan province, 1998 Ninety-four percent of the land area (383,390 km2) in Yunnan province is hilly, and 77 percent has a slope greater than 25 degrees. Soil erosion is a major problem because of concentrated rainfall events, heavy summer thunderstorms, geological structures with steep slopes, and improper farming practices.

Fertilizer use on different upland cropping systems for soil conservation in Yunnan province, 1997 This study examined the effects of balanced fertilization with alley cropping and vegetation terraces on the sloping lands of Yunnan. Best results were obtained with the combination of adequate fertilization and vegetative terraces. These terraces allowed for soil losses 34 and 135 times less than alfalfa/clover pastures or bare ground, respectively.
