Oklahoma farmer develops a healthy nitrogen diet for winter wheat with crop sensor technology

摘要

When drought destroyed the Oklahoma corn crop two years in a row, farmers were optimistic that the winter wheat that followed would be the bright spot. Yet, what was lurking in the soil tipped the scale in the wrong direction."Normal corn yields here are 100 to 120 bushels per acre. In a really good year, we'll see 150," says Brent Rendel, who farms in Miami, Oklahoma. "During the drought, most yields were in the 20- to 40-bushel-per-acre range. Many planted their wheat intothat and did not account for the residual nitrogen left over from the failed corn crop."
