U.S. farmers are expected to harvest their smallest winter wheat crop in more than a decade amid an ongoing drought that has devastated fields across the nation’s breadbasket and a global surplus of the grain that has depressed prices, according to USDA report.  U.S. soybean supplies are seen falling in the upcoming marketing year as domestic usage and exports are expected to remain strong even as production eases, the U.S. Agriculture Department said Domestic corn and wheat stocks are also expected to drop due to smaller harvests, according to the government's monthly supply and demand report. USDA, in its initial estimate of the 2018/19 marketing year, pegged soybean ending stocks at 415 million bushels, down from its forecast of 530 million bushels for 2017/18. Analysts' forecast for soybean ending stocks had ranged from 400 million to 715 million for 2018/19 and 495 million to 575 million for 2017/18, according to a Reuters survey. For corn, USDA put ending stocks at 1.682 billion bushels for 2018/19 and 2.182 billion bushels for 2017/18, in line with market forecasts. Wheat ending stocks were seen at 955 million bushels for 2018/19 and 1.070 billion bushels for 2017/18, both of which were above the average of analysts' estimates. USDA pegged U.S. winter wheat production at 1.192 billion bushels, down 6 percent from a year ago, due to drought in key production states such as Kansas, Oklahoma and Texas. Harvested winter wheat acreage was seen falling to a record low of 24.8 million. The last time the nation’s farmers harvested such a small wheat crop was in 2002, when U.S. production fell to 1.137 billion bushels. The government estimated the U.S. soybean harvest for 2018/19 at 4.280 billion bushels, down from 4.392 billion a year earlier. Soybean exports were seen rising to 2.290 billion bushels from 2.065 billion, while the domestic crush was projected to rise by 5 million bushels to 1.995 billion. The U.S. corn harvest was forecast at 14.040 billion bushels in 2018/19, down from 14.604 billion bushels in 2017/18. Exports were seen falling to 2.100 billion bushels from 2.225 billion bushels.
