Interpretive Summary

Application of Information Technology in Soil Nutrient Management and Balanced Fertilization in Xinjiang, 2005 Experiments on drip-irrigated cotton were conducted at the Third Fengshou Farm in Awati County while additional field trials and demonstrations were arranged in the monitored village of Awati County (corn) and at Toutunhe Farm (tomato and grape).

Application of Information Technology in Soil Nutrient Management and Balanced Fertilization in Xinjiang, 2004 Xinjiang has an arid to semi-arid climate that is well adapted to a variety of cash crops. Xinjiang is especially known for its cotton area, recently estimated at 1 million (M) ha. Current cotton output for Xinjiang is over 1. 5 M t. accounting for 37% of China's total. Besides cotton, Xinjiang is a major producer of tomato, grapes, and hops.

The Application of Information Technology for Soil Nutrient Management and Balanced Fertilization in Xinjiang, 2003 Cotton and wheat are the major crops for Xinjiang Province and are the focus of our balanced nitrogen (N), phosphorus (P), potassium (K) fertilization research for the region. A cotton field trial conducted in Hawati County found fertilization with 207-138-72 kg N-P2O5-K2O/ha produced the highest yield of 1,461 kg lint cotton/ha.

The Application of Information Technology in Soil Nutrient Management and Balanced Fertilization in Xinjiang, 2002. This project is gathering information on soil nutrient status to determine nutrient limiting factors for the region’s cotton producing area.

Application of information technology in soil nutrient managment of Xinjiang, 2001 Xinjiang is the largest cotton production area in China, and thereby, the primary focus for nutrient management research. According to previous work, nitrogen (N), phosphorus (P), and potassium (K) were considered the main limiting nutrient factors, followed by zinc (Zn), manganese (Mn), and boron (B). The contribution of fertilizer application to cotton yield was about 26 percent.
