| Abstract/Contents: | There are many claims of the benefits of humic products on turfgrass, which include: increased effectiveness of fertilizers, increased nutrient uptake and efficiency, a better-developed root system, and improved stress tolerances. However, minimal research has been conducted to substantiate these claims. The objective of this study is to evaluate soil health parameters of a sand-based turfgrass fertilized with humic substances while maintaining turfgrass quality. This is part of the first year of a two-year study conducted at the Iowa State University Horticulture Research Station in Ames, IA, on a Penncross creeping bentgrass (Agrostis stolonifera L.) putting green established over a sand-based rootzone meeting United States Golf Association specifications. Fertilizer treatments included: humic-coated urea (HCU; two rates), HCU + humic dispersing granules (HDG), HCU + black gypsum dispersing granules (BGDG), urea, HDG, and a non-fertilized control. There was a significant interaction between treatment and rating date for visual quality (VQ) and percent green cover (PGC). There was not a significant treatment effect for any of the measured soil parameters, which included cation exchange capacity, organic matter, and soil-test biological activity. Overall, the VQ for all treatments was greater than the HDG and non-fertilized. On 31 Oct., HCU + HDG (6.3) and urea (5.7) had a greater VQ relative to all other treatments (3.3-5.3). There were differences between PGC on two of the rating dates. On 24 June, all treatments including the non-fertilized (98.5-99.6%) had a higher PGC compared to HDG (96.8%). On 31 Oct., HCU + HDG (89.4%) had the highest PGC and all treatments (74.5-83.6%) had a greater PGC than the HDG (34.2%) and non-fertilized (48.6%). Overall, applications of humic fertilizers resulted in similar turfgrass VQ and PGC relative to urea. HCU applied at a decreased N rate maintained turfgrass VQ and PGC relative to the full N application rate. |
