The new Farm Bill has just been voted, after difficult negotiations between the White House and Congress. Since the beginning of the commodity-based programs in the 1930s, the agricultural policies in United States were aimed at supporting farm commodity markets and stabilizing farmers incomes. These commodity support policies have been an important contributor to the growth of agricultural productivity and commodity surplus. In the 1950s it became apparent that export demand was capable of creating farm prosperity and became important for the surplus disposal. The US agricultural policies aimed at expanding agricultural exports, and became more offensive as the export competition grew keener. For the first time in 1996, as the market estimates were optimistic, the Fair Act raised the possibility of an end to price support activities as a mean of farm income support. But in 1998 and 1999 weakened export demand led to marked reductions in the prices of the main crops. The 2002 Farm Bill restored the safety net for the farm income. Despite high prices and expansion of demand, and in contradiction with US commitments at the WTO, the new Farm Bill keep on aiming at providing a strong safety net for farm income, which allows the growth of agricultural productivity and the increase in US agriculture competitiveness, and at expanding trade.
