Abstract
<p>Soil degradation mostly occurs on land where a lack of surface coverage results in soil-aggregate destruction due to heavy rainfall. Turfgrass is an ornamental plant and covers the soil surface and, thus, potentially improves soil-aggregate stability. This study determined the potential of some summer grasses to improve soil-aggregate stability and was a pilot experiment using six turfgrass species: <em>Paspalum vaginatum</em>; middle-leaf <em>Zoysia sp.</em>; <em>Cynodon dactylon</em>; coarse-leaf <em>Zoysia sp.;</em> <em>Axonopus compressus</em>; <em>Zoysia matrella</em>. Turfgrasses were planted using stolons in a 0.6 m<sup>2</sup> plot unit with 5 cm x 5 cm space. Lawn maintenance included irrigation, fertilizing, and weeding. Soil characteristics were observed six months after planting and showed that turfgrass increased the soil-aggregate index from 42.3% to 83.0% in control, and carbon particles measuring 6.4 μm from 28.3% to 63.0%.</p>
