Reduce the number of tillage operations; consider no-tillage or minimum tillage practices. Don’t overwork the soil and don’t work the soil when it is too wet. Reduce tire pressure; high tire pressure concentrates the equipment weight on a small tire soil contact area resulting in ex cessive pressure in the wheel track. Use wider, so-called "floatation” tires; dual tires are still better. Another approach is to add organic matter such as manures or cover crops. The organic matter helps by making the soil 171 Quarry Rd.

They will support equipment better without pulverizing and compactuig. Damn says that sometimes a switch in equipment may help. For example, some report that a chisel plow will help break up the “plow pan” caused by moldboard plows. However, be careful that new equipment doesn’t require bigger, heavier tractors or more trips over the field. Check your fields for soil com paction, Daum urges. Symptoms include shallow root penetration, poor drainage, poor water holding capacity, large clods, poor crop performance and crusting.
