Interpretive Summary

Anhui Province is one of the major cotton production provinces in China with an annual planting area of 344,000 ha in 2010. However, cotton is planted in the region along the Yangtze River valley on mainly gray sandy soils that are (a) low in native soil fertility (organic matter 0. 95%, 32 mg nitrate-N/kg, 16 mg available P/kg, 86 mg available K/kg, 35 mg available S/kg and 0. 8 mg available B/kg) and (b) not fertilized in a balanced way.

Anhui is one of the major cotton growing provinces in China with two major cotton growing regions—the Yangtze river and Yellow river basins. Cotton is grown in the region on about 400,000 ha with a recent annual average production of 350,000 t. The soils of the Yangtze region belong to fluvial outwash or gray clay sand with low P and K (50 to 100 mg/kg). The Huaibei cotton region belongs to the Yellow river plain which has yellow fluvo-aquatic and Shajiang black soils.

Anhui province is one of the major cotton producing provinces in China with annual cotton planting area of 400,000 ha. Thus, the study of nutrient limiting factors and scientific fertilization technology for cotton is of great significance in Anhui. A field experiment was conducted in 2011 in Wuwei county by Anhui Agricultural University. Five treatments: a) OPT (N-P2O5-K2O = 225-150-225 kg/ha + FeSO4 22. 5 kg/ha + MnSO4 + ZnSO4 7.
