Compaction is a no-till farmer’s kryptonite. The benefits that no-till provides — reduced soil erosion, increased organic matter, efficient biological ecosystems, improved soil quality, higher infiltration rates, yield boosts and more — can quickly be reclaimed if compaction occurs.
Once he realized that subsoiling was unnecessary, Italian no-tiller Mauro Collovati created a wide-sweep-designed opener that performs well on his wide range of soil types.
Even established no-till fields could be damaged by traffic following the heavy rains that suddenly hit much of the Midwest, but ruts must be dealt with.
In many areas in the middle of the country, the dry summer suddenly turned extremely wet with widespread flooding, and even no-till fields were saturated and vulnerable to runoff problems.
Because of the enormous benefits, over half the corn in Kentucky is already being no-tilled. And the figure is much higher on the state’s erodible land.
Subsoiling can help improve yield potential of certain poorly drained soils, a six-year study by ag engineering researchers at Ohio State University (OSU) shows.
