Nevertheless, the monitoring of rooting depth and functional viability on a regular basis is an important dimension in any turf manager's information ass...
متن کاملNematicide treatments of turfgrass seed.
Seed treatments of improved Kentucky bluegrass and fescue cultivars with carbofuran, oxamyl, and phenamiphos dissolved in acetone reduced seedling emergence, but treatments were not extremely phytotoxic. Phenamiphos was the most toxic, particularly at the 5,000 mug/ml concentration. Fresh weight of grass clippings 35 d following planting generally was greater in treatments than in controls exce...
متن کاملExtension Turfgrass Maintenance Essential Elements
Actively growing turfgrasses usually contain more than 75 percent water. Their “dry” matter holds 16 nutrient elements considered essential for survival, flowering and/or seed production. Turfgrasses receive three of these, carbon (C), hydrogen (H) and oxygen (O), from carbon dioxide in the air and from water. The remaining essential elements are minerals, most often supplied by the soil. Healt...
