| Abstract/Contents: | "There is a lack of plant response to fertilizer K in some sandy soils even though routine soil tests for soil available K are shown to be low. This lack of plant response to K fertilization may be explained by K release from nonexchangeable forms. Greenhouse and laboratory experiments were conducted to evaluate a) response of 'Penncross' bentgrass (Agrostis palustris Huds.) grown in rootzones with different sand sources to K fertilization and b) K release from nonexchangeable forms from the different sand sources as an index to K availability. Experimental variables in the greenhouse were two K levels (0 and 250 mg K kg-1 soil) and eight sand rootzone sources. Rootzone soils were sub-irrigated to ensure no K loss from leaching. Two laboratory methods (boiling 1 M HNO3 extraction and continuous leaching with 0.01 M HCI) and total K uptake by the bentgrass were employed to index K release from nonexchangeable forms for each rootzone source. Potassium fertilization significantly increased bentgrass yield growing in one rootzone source and root weight in three rootzone sources. Potassium uptake by bentgrass and the two laboratory methods showed important differences in K release from the sand rootzones. The K removed by the two laboratory methods was closely related to leaf tissue K and K uptake, with the 1 M HNO3 extraction method providing the closest fit. The study suggests that release of K from primary minerals in some rootzones with high sand content is proceeding at rates to satisfy bentgrass requirements for K. The 1 M HNO3 extraction method may provide an alternative to the routine laboratory procedures presently being used to measure the extractable K in sand-based constructed putting greens by measuring K contributed by nonexchangeable forms." |
