| Abstract/Contents: | "This study was undertaken to determine if N:K ratios and potassium carriers affect turf performance as based on growth, nutritional status and stress tolerance. Cynodon dactylon x C. transvaalensis cv. Tifgreen was fertilised with N:K ratios of 2:1, 1:1, or 1:2 for a period of three years. Treatments included a standard N rate of 30g N per square metre with the corresponding K rate to match the ratio. Carriers included KCl, KāSOā, and sulfur coated KāSOā. The turf was grown on a USGA soil mix and had been established for 7 years. The area was mown at 6 mm and irrigated to prevent moisture stress. Turf performance was evaluated for quality and growth rates. Tissue analysis determined nutrient levels. Plugs were taken for root mass analysis and during the winter were subjected to freeze stress studies to determine winter hardiness and soil samples were analyzed for nutrient content. Treatment differences in growth rate of up to 20% were found. Differences were noted among treatments for tissue K levels with values ranging from 1.55 to 1.85%. No turf quality, colour, rooting, or cold tolerance differences were found. Even under low levels of K availability in the soil (8 to 21 mg kg āā), tissue K levels remained as high as 1.1%, indicating that Tifgreen is a very efficient absorber of potassium." |
