Soil Physical Conditions after Plowing and Packing of Ridges

Abstract

A system of seedbed preparation by moldboard plowing and packing small ridges appears to fulfill two requirements for successful seeding-control wind erosion and eliminate competing vegetation. The percentage by weight of soil aggregates larger than 0.833 mm increases greatly with an increase in the moisture content of soil at the time of packing. A sandy loam soil should contain 9 to 12% moisture when packed to obtain a surface condition greatly resistant to wind erosion.
