Última OPTIMUM WINDBREAK SPACING IN GREAT PLAINS AGRICULTURE AgEcon Haag, Andrew A.; Helmers, Glenn A.; Brandle, James. Integer Programming determined an optimum windbreak pattern for corn and soybean production. Direct costs included windbreak establishment, annual maintenance, and removal. Crop yields were included as a linearized function. The net return results for the optimum pattern were 12 and 16 percent over conventional production for corn and soybean respectively.

Ano: 2002 URL: http://purl.umn.edu/36589 RISK-RETURN ANALYSIS OF INCORPORATING ANNUAL LEGUMES AND LAMB GRAZING WITH DRYLAND CROP ROTATIONS AgEcon Held, Larry J.; Haag, Andrew A.; Krall, James M.; Delaney, Ronald H.; Miller, Stephen D.. Profitability and risk, 1988-2001, are examined for lamb-grazed field pea as a fallow alternative with wheat, or an extended wheat-sunflower-millet rotation. Switching from conventional wheat-fallow to an extended rotation with grazed-peas increases profitability (2.3% to 7.3%), and reduces risk (below 0% target in only 2 versus 7 of 14 years).
