Oats Date-of-Planting Study 1997-1998

In the 1990’s, oat yields averaged between 60 and 75 bu/a in the upper Midwest and were grown mainly for supplemental feed and straw for livestock. However, on farm research has shown that when oats are well managed, 100 bu/acre yields of high quality oats are common (see “A Farmer’s Guide to Quality [...] More »

Using Small Grain Cover Crop Alternatives to Diversify Crop Rotations.

Increasing the sustainability of farming systems by adding small grains and legume cover crops to the corn-soybean rotation was examined. Production and economic data collected from participating farmers indicate that small grain yields were 25% above state averages and high quality grain resulted in 25% higher prices at the elevator. Synthetic N fertilizer inputs were [...] More »

Cropping system three Chemlite satellite trial-Arlington, 1995 and 1996

In spite of very low corn yields in 1992 and 1993, and below average wheat yields, almost every year, Cropping System 3 (CS3) has been at least as profitable as the continuous corn system. It is not clear however, how much of the profitability of CS3 is due to the zero purchased input philosophy [...] More »

Corn response to commercial fertilizer in a low input cash grain system

Introduction Corn yields were lower than expected in the corn-soybean-wheat/red clover (CS3) rotation during the 1992 and 1993 growing seasons. Experiments were initiated at LAC and ARS in 1994 to determine the cause of the low yields and to find out whether adding some purchased inputs would be cost-effective. Soil fertility and weed pressure [...] More »
