The Environmental Program includes seven treatments designed to minimize irrigation and chemical inputs, while providing for a healthy and attractive lawn.
Weed control is similar to that of the Traditional Program, as organic means of weed control have proven to be impractical and unreliable.
“Soil wetting agents”, “plant growth regulators”, beneficial micro-organisms, and other organics are used to minimize the overall chemical inputs needed to maintain a quality lawn.
Landscape and environmental benefits include a reduced demand for irrigation, increased disease resistance (reducing the need for fungicide), good color with reduced quantities of fertilizer, and denser growth habit. Also, with decreased top growth, mowing frequency may be reduced, lowering carbon monoxide emissions.
Soil wetting agents, commonly used in golf course management, are used to improve uniformity of water penetration, optimize water use, and reduce loss through evaporation. This results in less demand for irrigation frequency.
Plant growth regulators (PGR’s) reduce vertical growth rate, resulting in less demand for water. PGR’s also improve color by concentrating chlorophyll (green pigment) within the plant cells, as cell elongation is minimized. PGR’s have also been found to help in areas with limited sunlight, improve turf hardiness, and reduce disease incidence.
Organics improve soil moisture holding capacity and feed the biological system within the soil. With good soil biology, beneficial microorganisms are enhanced.
