Organic material improves soil structure.
Organic
material can be added to sandy soils to increase nutrient and moisture
retention. Clay soils can also be amended with organic material to help loosen
the soil and provide better aeration and drainage. Soil
pH
The age old axiom stating soil pH should be 7.0 (the sweet
level) does not ring true.

For best overall results, adjust to your lawn turfs ideal pH.
Sulfur lowers pH and lime raises it.Note:
Most broadleaf weeds like soil pH above 7.0. With the
exception of St. Augustine grass, ideal pH is a deterrent to broadleaf weeds such as crabgrass.
Bio-enhanced amendments such as Aerify (a soil aerator) and
biological dethatcher build and support soil life devastated by years of
non-organic chemical and synthetic lawn care products.
