| Abstract/Contents: | "The study was establsihed in the fall of 1993 in an effort to define the factors that regulate bentgrass response to a dormant Milorganite application. The first-year results of this study provide evidence that microbial mineralization of organic N in dormant-applied Milorganite can occur during winter and the N released stimulates spring greenup of creeping bentgrass. The amounts of N mineralized over the winter months averaged 0.18 lb N.M, or about 11% of the N applied. Early spring mineralization of dormant-applied N is influenced by anything that affects soil temperature. In this study, surface drainage was more important in this regard than was height of cut the previous season or color of topdressing material. The influences of these three factors were found to be additive. When good surface drainage was combined with a 3/8-inch mowing height and charcoal topdressing, spring greenup of the bentgrass prior to April 20 was approximately one week ahead of greenup in bentgrass growing on a poorly drained site, mowed at 5/8 inch topdressed with sand. The study is being contined for at least one more winter. More evidence has already been collected that shows mineralization of Milorganite organic N is significant when soil temperatures range from 40 to 50 degrees." |
