Infiltration Of Liquid Dairy Manure Into Soil, William R. Detar

William R DeTar

BASIN infiltrometers and double-ring infiltrometers were used on the subsoil of four different soils to determine the infiltration rate of various concentrations of liquid dairy manure. Raw manure was diluted with water by ratios varying from 3:1 to 50:1. The liquid used for most of the tests did not contain the heavy fibers that tend to settle out immediately after mixing. Total solids, St, was the primary measure of concentration, and steady-state infiltration with water, Iw, was the indicator used for the type of soil. It was found that the infiltration rate was proportional to Iw^0.11st^-.67 at one week. All …
