Biological
fertilizer is defined as a fertilizer containing no
chlorine, having an internal carbohydrate source,
and a salt content less than 200 lbs per acre at the
application rate. Turfdoctor we've done thousands
of Reams soil tests in our area and developed a fertilizer
blend that not only meets all biological fertilizer
requirements, but also will help reduce weed, insect,
and disease pressure by proper mineralization of the
soil.
