10 Ways for No-Tillers to Beat Compaction Challenges

More axles, lower tire pressure, controlled traffic, cover crops, and a dose of patience can keep compaction from hurting yields.

No-tillers planning to achieve better yields in the next growing season ought to look a little ‘deeper,’ so to speak, than just seed and inputs.

After above-average precipitation hit many states again in 2016, what shape are your fields in after planting, spraying and harvesting?

Pinch-row and subsurface compaction can cause double-digit decreases in crop yields, and the effects of compaction can linger for several years.

ALL IN ONE. The Tribine Harvester features a combine with a 1,000-bushel grain bin to eliminate the need for a chasing tractor and grain cart, potentially reducing compaction.

Research in the northern Corn Belt from 1988-2002 showed deeply compacted soils depressed corn and soybean yields 5-6% for 12 years, compared with an un-compacted control site — even though…
