Quarries are required to provide a chemical analysis of their product.
Be aware that some quarries may have a product that contains heavy
metals or toxic elements. Do the necessary research before hauling tons
to your fields.
Generally the crusher "fines" are the most readily available to soil life.

Free for the hauling;
usually $50-75/tandem load.
