What is a Biological Fertilizer?

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.

TDI has developed numerous special blends of Biological fertilizers that not only meet all these requirements but are specific to certain grass types’ needs. Our custom fertiizers also help reduce weed, insect and disease pressure by proper mineralization of the soil.
