On March 29th, 2018, the USDA surprised everyone in its 2018 Prospective Plantings release by reporting U.S. new crop corn and soybean acres at well below trade expectations. Total U.S. principal crop acres fell by 1.16 million year-on-year (Y/Y), to just under 318 million acres (mil acres). 2018 U.S. corn acreage came in at 88.02 mil acres (trade expected range was 87.55 – 91 mil acres), which is down 2.1 million Y/Y, and soybeans at 88.98 mil acres (trade expected range was 89.90 – 92.60 mil acres), which is down 1.16 mil acres Y/Y. The drop reflected a switch to other more profitable crops, with less intensive input costs, and to crops that are less sensitive to any Chinese trade tariff retaliation/backlash.
The Farms.com Risk Management 2018 Ontario farmer survey conducted from February 4th – March 25th, 2018 is suggesting that Ontario farmers intend to plant more corn and wheat acres this year and less soybean acres, compared to Stats Canada’s final 2017 acres

Ontario farmers intend to plant 6.02% more corn acres Y/Y or up +135,796 acres to 2,255,796 acres in 2018, and remain above the 5-year average across all regions of the province. The highest increase is coming from the regions of Central and Southern Ontario. 2018 soybean acres at 2,891,680 will dip back below the 3-million-acre mark and below the 5-year average. This is down -7.46% Y/Y or -229,234 acres, with most of the decline coming from Southern Ontario. Central Ontario, however, is planning on planting 61,700 more soybean acres in 2018. IP soybean acres will also be up +6.67% Y/Y. All Wheat acres will remain above the 5-year average and up slightly Y/Y to 1,052,408 acres. This is up 4.2% Y/Y, with the largest increase seen in both Eastern and Northern Ontario.
