United States Agriculture

Between 1979 and 1991, the amounts of herbicide apphed in the United States have remained constant, but the expenditures on herbicides have increased 54%. Agricultural costs accounted for ah. of this increase and more, since herbicide user expenditures in the government/commercial and home sectors combined dropped 3 to 4% during that period. Increased weed control costs related to crop protection have also contributed to the 37% increase, since 1988, in total annual user expenditures for pesticides in general, ie, herbicides, fungicides, and insecticides. In the United States, agricultural uses (ca 1993) account for more than 67% of total pesticide user expenses and 75% of the quantity used annually. Herbicides are now the lea ding type of pesticides in terms of both user expenditures and volumes used (1). [Pg.54]

Soil erosion, therefore, is the greatest threat to the economic and environmental sustainability of United States agriculture (Mueller, 1995). Pimentel et al. (1995) concluded that soil erosion is a major environmental and agricultural problem worldwide, and efforts to reduce these losses must be supported. Erosion rates have exceeded replacement values on most sloping fields since the Europeans introduced plowing and grain farming as North America was settled. [Pg.522]

The Agriculture Department was budgeted 354 million, a 26% increase, for bioterrorism defense activities, the State Department 71.8 million, and the National Science Foundation 31.3 million, particularly, in accordance with Homeland Security Presidential Directive 9 (HSPD-9), Defense of United States agriculture and food, January 30,2004. Finally, the Environmental Protection Agency received an 87% increase to 185 million, primarily for decontamination capabilities, to protect water and food supplies, and for training, the study says. [Pg.1624]

As mentioned, the water-holding capacity and nutrient levels of soils are lessened when erosion occurs. With conventional com production, erosion reduced the volume of moisture in the soil by about 50% compared with no-till corn culture. In contrast, soil moisture volume increased when com was grown in combination with living mulches. Estimates are that about 20 billion in fertilizer nutrients are lost annually from United States agriculture because of soil erosion. [Pg.13]

Boron. Virtually all United States boron production and about three-fifths of the world production comes from bedded deposits and lake brines in California. U.S. reserves are adequate to support high production levels. Turkey is the only other boron-producing country of significance. Only about 5% of boron production is used in agriculture. [Pg.245]

Eor the products under its jurisdiction, eg, meat and meat products, the United States Department of Agriculture (USD A) has requirements similar to those of the EDA. However, mustard and spices that impart color must always be listed separately onion and gadic powder may be listed simply as flavors. [Pg.23]

In the United States, novel food ingredients or food ingredients produced by novel processes must be cleared by the FDA. In the case of meat and poultry, novel ingredients must also be cleared by the U.S. Department of Agriculture s Food Safety and Inspection Service (FSIS). [Pg.472]
