Hilgenkamp, R. - Lime Use in a Corn and Soybean Rotation
Research Objective(s)
:
To determine the profitability of using lime on acid soil in a corn/soybean rotation.
Summary
:
A 2-ton lime application with a 7-year life expectancy was applied in spring 1995. A significant difference was detected between test weights at the 90% confidence level in 1995. In 1996, there was a significant difference in moisture content of seed at harvest. In 1997, the use of lime increased corn grain yield slightly. In 1998, lime increased seed yield of soybeans significantly; however, seed test weight was reduced. In 1999, lime reduced grain moisture at harvest and resulted in a slightly lower test weight. In 2000, the lime application resulted in higher seed yield, slightly higher moisture, and slightly higher seed test weight. In 2001, grain moisture was lower at harvest where lime had been applied. In 2002, seed yield of soybeans was increased significantly by lime. In 2003, grain yield of corn was increased and grain test weight was higher where lime had been applied. Seed yield was again higher in 2004 where lime had been applied in 1995. Lime application had no effect on corn in 2005; however, soil pH was still higher where lime had been applied. In 2006, soybean seed yield was signifcantly higher where lime had been applied. the grain moisture of corn was significantly lower are harvest in 2007 where lime had been applied. Soil pH was higher in the fall of 2007 where lime had been applied and soybean seed yield in 2008 was significantly higher from lime application.
