CMREC Turfgrass Evaluation Trials

One of the most crucial decisions made during the establishment of a turf is the proper selection of seed or seed mixtures. Turfgrasses must be selected according to their adaption to the particular site and intended use. Improper seed selection and/or poor seed quality will lead to poor turf. Use of a turfgrass species or variety that is not adapted to your site conditions will result in a weak, thin, and unattractive turf that is subject to soil erosion and weed encroachment. Consequently, a higher level of maintenance will be necessary to maintain a desirable lawn.
Incorporating compost is one of the best ways to improve existing soil for the long-term no matter the soil type. Compost increases water and nutrient holding capacity in sandy soils. In clay soils compost improves drainage. It is a common practice to apply compost just before seeding a new lawn or laying sod. An additional need is to reduce nutrient pollution to the Chesapeake Bay watershed and public scrutiny of lawn maintenance practices and the nutrient management laws in Maryland justify turfgrass trials with minimal maintenance practices.
Turf plots were established at CMREC, Clarksville in 2009 with compost additions and no compost additions to observe long term effects of low maintenance practices on standard turfgrass cultivars used for home lawns. These plots continue to be maintained and observed for practical quality performance under low maintenance regimes.
