Five years of research show that there are many benefits to conservation tillage
on furrow-irrigated land. Benefits are enhanced when cropping sequences are altered to
accommodate the fewest number of tillage operations over the entire cropping sequence.
Results showed that soil erosion can be reduced 47 to 100 percent, crop yields can be
sustained, and farmer net income can be increased an average of more than $125 ha-1
each year over a 5-year cropping sequence
