Porter Farm, near Terrell, Texas was the site of the first cooperative farm demonstration, organized by Dr. Seaman A. Knapp in 1903. The project successfully demonstrated methods expanding crop production. From this foundation project developed the U.S. Department of Agriculture Agricultural Extension Service. Knapp worked with Walter Porter to set aside of the farm, on which the experimental use of fertilizers on some plots and rotation with nitrogen-fixing legumes doubled normal yields of cotton. Porter had been selected by the community to participate in the project, with $1000 set aside to cover potential losses. Porter profited from the experiment, and the money was unused. The success of this project led to the Extension Service programs, which went on to develop methods to combat boll weevil infestation in the area. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Porter Farm」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
