Is there any product availabe to break down clay soil?
I am a landscape contractor who has dealt with clay soils for forty years. My answer may strike you as funny but I offer it in all sincerity. The best tool for breaking down clay soils is a sharp mattock. The best products are agricultural gypsum and compost.The cheapest way to introduce gypsum into your clay soil is to use wallboard scraps which are available for free from any construction site The cheapest way to introduce compost is kitchen scraps if time is not of the essence or you can use a combination of coffee grounds available for free from coffee houses mixed with leaves and sawdust which are also available free. The mixture of coffee grounds and sawdust is especially synergistic because while both contribute to soil tilth and provide organic matter, the grounds provide the nitrogen needed by the sawdust to breakdown into nutrients available to plants.These soil amendments must be worked in with liberal amounts of good old-fashioned elbow grease.
