Interpretive Summary:

Technical Abstract: This is digital research data corresponding to a published manuscript, Corn stover removal responses on soil test P and K levels in Coastal Plain Ultisols, in Sustainability. 2021. 13:4401. Corn (Zea mays L.) stover is used as a biofuel feedstock in the U.S. Selection of stover harvest rates for soils is problematic, however, because excessive stover removal may have consequences on plant available phosphorus (P) and potassium (K) concentrations. Our objective was to quantify stover harvest impact on soil P and K concentrations in the southeastern U.S. Coastal Plain. Five stover harvest rates (0, 25, 50, 75 and 100 percent by weight) were removed for five years (2008 to 2012) from replicated plots on highly weathered, toposequential Coastal Plain Ultisols. Grain and stover mass with P and K concentration data were used to calculate nutrient removal. Mehlich 1 (M1) extractable P and K concentrations and bulk density were used to monitor changes within the soil.
