Abstract

Liming soils is an important part of the overall fertility program for soybean production. The decision of whether or not lime is needed is generally based on the soil pH. Soybeans are adversely affected by acidity when the pH falls below about 5.8. Considerable interest exists in Iowa about soil pH specific management recommendations. Because soil pH varies across Iowa, it is likely that the current optimum plant population for soybeans needs to be adjusted depending on soil pH. The objective of this study is to identify the optimum plant population for soybeans at various levels of soil pH.
