Abstract/Contents:"There is a great potential for leaching fertilizer nitrogen (N) from golf greens because of their sandy textural class, method of construction and management. Although soil organic matter (SOM) is acknowledged as a great source of N and some other nutrients, its role as a N source seems to be neglected in the management of golf greens. The degree of protection of SOM is one indication of how active a role SOM plays as a nutrient source. The more protected SOM should be less active in nutrient cycling. Binding to calcium or other cations could be one source of chemical protection. An extraction method developed by Olk et al. (1995) distinguishes humic acid (HA) fractions by their binding to the dominant stabilizing soil cations and separates them into calcium-bound (CaHA) and non calcium-bound or mobile (MHA) fractions. MHA is a relatively young, N-rich HA fraction that does not appear to form stable complexes with calcium. The MHA could therefore play a greater role in nutrient availability than CaHA. We hypothesized that the MHA fraction of SOM could account for a significant portion of available N in golf greens. In order to test this hypothesis, preliminary data was collected on the amount and distribution of MHA and CaHA in golf greens ranging in age from 4 to 34 years."
