Resumen
Descripción
Costs and net returns for
conventional tillage (CT), reducedtillage
(RT) and no-tillage (NT) are
evaluated for five cropping systems:
continuous soybean, a soybean-grain
sorghum rotation, a soybean-wheat
rotation, continuous grain sorghum
and continuous wheat, over a period
of increasing input and output
prices, 2006-2008. NT had the
highest net return for all of the
systems with soybeans each year.
NT also had the lowest energy use
for all systems. The net returns of
NT increased relative to CT and RT
from 2006 to 2008 for all of the
systems with soybeans. However,
this increase in net returns was a
result of increasing commodity
prices rather than a slower increase
in costs for NT.
