Soil Nutrient Management in Monitored Village in Jianghuai and Huaibei Districts, Anhui, 2006 Winter wheat and summer maize are the main food and forage crops in the Huaibei Region of Anhui Province. The annual area of winter wheat is 1. 512 million (M) ha, while the summer maize area covers 0. 432 M ha. Thus, the Huaibeu Region accounts for 74% of winter wheat area and 84% of the summer maize area in the province. Read more

Interpretive Summary

Soil Nutrient Management in Monitored Village in Jianghuai and Huaibei Districts, Anhui, 2006 Winter wheat and summer maize are the main food and forage crops in the Huaibei Region of Anhui Province. The annual area of winter wheat is 1. 512 million (M) ha, while the summer maize area covers 0. 432 M ha. Thus, the Huaibeu Region accounts for 74% of winter wheat area and 84% of the summer maize area in the province.

Soil Nutrient Management in Monitored Villages in Jianghuai and Huaibei Districts, 2005 Winter wheat and summer maize are the main grain crops in Huaibei Region of Anhui Province. Winter wheat area consists of 1. 5 million ha (M ha), while the summer maize area represents 432,000 ha. Rapeseed is the main oil crop, with a planted area of 529,000 ha. Fertilization of these crops primarily consists of nitrogen (N) and phosphorus (P) and little or no potassium (K).

Soil Nutrient Management Monitored Villages in Jianghuai and Huaibei Districts in Anhui, 2004 Winter wheat, maize, soybean, and rapeseed continue as the main crops in Anhui Province. Unbalanced fertilization in these crops is one of the most important yield- and quality-limiting factors.

Soil Nutrient Management Strategies for Monitored Villages in Jianghuai and Huaibei Districts, Anhui, 2003 Balanced fertilization (BF) demonstrations held at 10 farmers’ fields clearly showed the inadequacy of common farmer practice (FP). Wheat yields improved from 4. 3 t/ha (FP) to 5. 0 t/ha (BF) and raised the average net income by US$79/ha. In maize, results from 23 farmers’ fields produced a maximum yield of 3. 2 t/ha (FP was 2. 8 t/ha), which raised average net income by US$63/ha.

Soil Nutrient Management Strategies for Monitored Villages in Jianghuai and Huaibei Districts, Anhui Province, 2002. Analysis of 273 soil samples from yellow-drab and paddy soils around Jianghui showed that soil nitrogen (N), potassium (K), zinc (Zn), phosphorus (P), and boron (B) were insufficient, while calcium (Ca,) magnesium (Mg), sulfur (S), manganese (Mn), and copper (Cu) were abundant.

Soil nutrient-monitored villages in Jianghuai and Huaibei districts of Anhui province, 2001 The Jianghui soil nutrient monitoring village was established to represent soil types and agricultural production conditions in yellow-drab soils of the northern sub-tropical zone. The village has 2,180 people and 263 hectares (ha) of cultivated land (161 ha in paddy fields). Soil samples (373) were collected (100 m2 grid) and will be analysed to determine nutrient content and variability.
