Abstract

Relatively small amounts of nitrogen (N) were needed to maximize profits in dry parts of the state last year. This observation deserves attention now because soils are dry in much of the state and because N prices may be unusually high next spring. Evidence in support of this conclusion was obtained in precision farming trials conducted at three sites, two in Greene County and one in Hamilton County. Each trial covered approximately 80 acres of corn after soybean. Yields of corn seemed to be severely limited by lack of rainfall at the two sites in Greene County and somewhat limited by rainfall at the Hamilton County site.
