Minimizing Wheel Traffic Damage to Alfalfa
by Dan Undersander
What damage is caused by wheel traffic?
Wheel traffic is known to increase soil compaction which, on some soils, reduces macropore air permeability, soil water infiltration and root development of alfalfa. All of which reduce yield. However, our research has indicated that the largest effect of wheel traffic is to break off regrowing alfalfa stems thereby reducing next cutting yield.
How much is yield of next cutting reduced?
