Nitrogen Management on U.S. Corn Acres, 2001-10.

摘要

Farmers adjust the management of their crops for a variety of reasons. As input or output prices change, farmers motivation to conserve nitrogen fertilizer may change too. Other factorssuch as conservation program benefits, yield or revenue risk, and environmental regulations (ongoing or anticipated)also affect the level of nitrogen management observed on U.S. farms. An examination of nitrogen management on U.S. corn acres in 2001-10 indicates that farmers might be adjusting to changing economic conditions.
