Agriculture is a major user of ground and surface water in the United States, accounting for approximately 80 percent of the Nation's consumptive water use and over 90 percent in many Western States. Efficient irrigation systems and water management practices can help maintain farm profitability in an era of increasingly limited and more costly water supplies. This study aims to investigate the effect of climate change on transportation flows and inland waterways in the Mississippi River Basin due to climate-induced shifts in crop production patterns in. During the same period the population of Montana had more than doubled to , people. In his annual report, F. B. Linfield noted that from to , milk production increased 5-fold while dairy cows only increased 3-fold.

As a result of the acreage reductions in other regions, the Northern Plains increased its share of wheat production from % to %, even though acres planted was stable. The Mountain region also increased its share of wheat production from % to 17%. For the total United The model predicts that imposing a surcharge on irrigated land is likely to result in less irrigated acreage but is also likely to increase the intensity of chemical use on the remaining irrigated acreage. Depending upon soil and site characteristics this may result in increased total chemical leaching and environmental contamination. USDA strives to sustain and enhance economical crop production by developing and transferring sound, research-derived, knowledge to agricultural producers that results in food and fiber crops that are safe for consumption. Crop Acreage and Yield Crop Acreage and Yields USDA produces charts and maps displaying crop yields, crop weather, micromaps, and crop acreage animations.
The production volume of herbicides increased by 5% from to ; the fungicide volume decreased by 47o, while the in- secticide volume increased by 1%. The combined production volume of syn- thetic organic pesticides increased by 2%. Consequently, although total U.S. ECM production increased by % between and , total GHG emissions from this milk production increased by only %. Considered planted: (1) Under former farm bill programs, in calculating base acreage, land was considered planted to a program crop if it was used for conservation acreage under an acreage reduction, diversion, or set-aside program; was devoted to the production of commodities permitted under 0/85 and 50/85; was determined to be failed acres.
