Managing Healthy Sports Fields: A Guide to Using Organic Materials for Low-Maintenance and Chemical-Free Playing Fields
The huge chemical arsenal once available to turf managers for pest, weed and disease control has slowly but surely been restricted or regulated. As a result alternative methods have had to be sought. This text aims to liberate the modern turf manager from dependency on chemical treatments through suggestions you can adapt to specific field types, climatic zones, and desired appearance. Author Paul Sachs offers safety for people and animals, as well as longevity for the land, without sacrificing the quality of the turf itself.
