| Abstract/Contents: | "Turf managers generally recognize the importance of potassium (K) for turfgrass maintenance, and frequently consider sodium (Na) a potential hazard. Because of this, they may apply additional K when soil-test Na equals or somewhat exceeds that of K. To examine this reasoning, a two-year study was conducted utilizing cv. Tifway bermudagrass (Cynodon sp.) on a native sand soil and Tifdwarf bermudagrass on a USGA green. The green was overseeded with Poa trivialis in November of each year. Potassium (from KCI) was applied monthly at 0,1.25, 2.5, and 5.0 g m-2. Nitrogen was applied twice monthly at the rate of 10 g m-2 month-1. Sodium (from NaCl) was applied at rates that, in combination with applied K, were equivalent to the highest K rate on a molar-adjusted basis. The turfgrasses were evaluated for visual quality, clipping yield, and the K and Na content of clippings. Bermudagrass visual quality generally was reduced by K fertilization rates below 5 g m-2 month-1, both on the native soil and on the USGA green, and clipping yields were reduced occasionally. Sodium fertilization, however, generally did not affect bermudagrass quality and growth. Sodium concentration in clippings increased with decreasing K fertilization, and was markedly greater in the complete absence of K fertilization, even when no Na was applied as fertilizer. It appears that in non-saline non-sodic soils the rate of K fertilization for bermudagrass does not have to be modified in response to Na additions or soil-test Na, even up to or somewhat exceeding the rate of K fertilization or soil test K." |
