This publication offers information on water quality challenges in irrigation water.
Proper application of pesticides and fertilizers, which protects water quality, is possible only with a sprayer or spreader that is accurately calibrated. Pesticides applied with equipment that has not been calibrated may be misapplied by more than 10 percent. That may lead to repeat applications, damaged plants, excess cost, and contamination of the environment.
Lawns are ecosystems that impact surface and groundwater systems. The grasses found in lawns clean the environment by absorbing gaseous pollutants and intercepting pesticides, fertilizers, dust, and sediment. Irrigation water properly applied to lawns remains on site to recharge water supplies. In addition, grasses release oxygen and reduce glare, noise, and summer temperatures. Proper management practices need to be developed and followed to protect this environment. The purpose of this publication is to provide you with management strategies to preserve and protect water resources.
This factsheet provides information on how to keep a lawn healthy and attractive and how to protect the environment by reducing runoff and trapping pollutants. Fertilizer facts and rates, a mowing guide, and watering recommendations are included.
Although groundwater and surface waters are rarely polluted by turfgrass pesticides, turf managers should consider the potential for environmental contamination when choosing a pesticide.
This publication describes the best management practices (BMP) to reduce sediment and keep nutrients and pesticides applied to turf from contaminating North Carolina's water resources.
