ABSTRACT:
A method of restoring soil porosity and permeability to soils adjacent to home leach trench septic systems, increasing rates of aerobic decomposition of accumulated organic matter, breaking up and unplugging side walls of failed trenches, increasing leaching rates of waste liquids into surrounding soil. Soil is lifted from an 18" depth by a tillage tool. Bulk density is decreased.
