摘要

A LOOK AT THE BEST WAYS TO AVOID SOIL COMPACTION. Are tracks or tires better for reducing compaction from loaded grain carts? "The answer is, it depends," says Randy Taylor, an Oklahoma State University Extension ag engineer. At one of his recent soil-pit demonstrations showed the relative differences in shallow and deep compaction between heavy grain carts equipped with tires or tracks. A 729-bu. grain cart on tracks at 16 psi, loaded with 700 bu. of corn, created less compaction in the top 6-8 in.than carts equipped with 800/65R32 radial tires or 30.5-32 bias ply tires, both inflated to 30 psi. "That's what we would expect," Taylor says.
