The alkaline Humic products are designed to restructure soil. Soil becomes or is compacted because it has clay particles that have bonded together into a large solid mass. The theory behind humic products is that it encourages the clay to form individual particles that are not packed into an impermeable mass. I have soil that is the texture of grease when it is wet. Aeration with hollow core machines leaves masses of mud that is the texture of grease. I do not use the product thegrassfactor uses. I use a sprayable humic/fulvic concentrate. After a year of treatment, soil that started out with the texture of grease is now more like loam.
