1. Residual P Effects on Soybean Yield and Nutrient Removal RatesLong-term experiments were conducted from 1997-2003 on a Nicollet-Webster clay loan soil complex at Waseca, MN to determine the availability of residual P applied for corn on the yield and removal of P by soybeans in the following year. Phosphorus was applied either with the seed at planting as a starter, 5 to 6" deep in a band in the fall, or broadcast and incol-porated by tillage. Tillage systems included no till, strip till, spring field cultivation, and chisel plow plus field cultivation. Tillage... |
2. Continuous Corn Production As Affected By Starter Fertilizers Containing Nitrogen, Phosphorus, and SulfurCrop rotations in the Midwest have changed from the traditional corn-soybean rotation to more corn-intensive rotations. Due to the expanding demand for corn to supply the ethanol industry and the increasing insect and disease challenges facing soybean producers, some farmers are switching to a corn-corn-soybean rotation or for some, continuous corn. These rotations produce large amounts of biomass (corn stover) that often remain on the soil surface with present day tillage systems. This is good... |
