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.
