WIN stands for water insoluble nitrogen. This is one type of slow-release nitrogen. Nutrients in the soil move with water. Over-watering causes nutrient leaching and possible environmental damage. Summary Remember, to protect the environment, your lawn management program must consider BMPs for pest management and fertilizer management.
Water management is a component of each.
Utilization of the BMPs presented in this brochure will make you a steward of the environment. In most cases these BMPs will not increase your costs. This brochure, WQ-28, was prepared by R. L.
