Conservation tillage means any minimal tillage system that leaves the soil
surface at least 30 percent covered by crop residue. No-till, in
which the soil is left undisturbed by tillage and the residue is left on
the soil surface, is most effective soil-conserving system.
Conservation tillage benefits water quality because it reduces soil
erosion and run-off. Soil erosion degrades the quality of our soils
resource by washing nutrients, organic matter, and minerals. Also,
run-off carries fertilizer and pesticides which impair water quality.
The bottom line or profitability of the farming enterprise also
benefits from conservation tillage. Yields are as good or better
that with reduced or intensive tillage systems when attention is paid to
management details. Increased infiltration and increased organic
matter are especially important on droughty soils and may help the crop
through a persistent dry period. Each tillage trip reduces available
moisture by about one half inch. In many cases the time saved by
reducing tillage trips is a key factor. The producer has more
time available for other farming activities. No-till can reduce fuel
consumption by 3.5 gallons per acre compared to conventional
tillage. Finally, less machinery means fewer pieces needed to be
replaced. Economists report this amounts to a $5 per acre reduction
in costs.
