The StaffIncreased soil pore space allows for greater water infiltration and retention, increased oxygen and CO2 exchange, and reduced compaction, all enabling roots to grow deeper. SuperSoil is a liquid compaction-relief product that increases soil pore space by combining small soil particles to create larger ones. The product negatively charged polymers dissolve alkaline salts, allowing bicarbonates to move deep into the soil profile and out of root growth areas. SuperSoil is a once or twice-a-year solution. SuperSoil is NOT a surfactant, wetting agent, polyacrylamide or penetrant. Ask about the 100% money-back guarantee on the performance of SuperSoil. No known chemical incompatibilities.
