Show Deep Tillage Drains Off Swamps and Water Holes "Water holes and temporary ponds on many farms can be drained by deep tillage practices, which includes in-cludes the heavy application of lime on the surface or in the subsoil," advises C. M. Nissley of Rutgers U. "This makes conditions favorable for deep-rooted crops which help to open up the soil." The practice would not be applicable appli-cable to fields where the surface soil is underlaid with three or more feet of clay, however. Because of this, Nissley suggests that a hole three feet deep or deeper be dug in order to find out the character of the soil formation before remedial measures are put into practice. He also suggests that the county agricultural agri-cultural agent be consulted for additional addi-tional advice on deep tillage prac tices. |
