| Abstract/Contents: | "A recent craze here in the Northwest involves the use of high levels of micronutrients, while greatly reducing nitrogen...until recently, I really didn't know about ehat the program was about since it is 'secret' and only available to clubs who pay a large fee and agree not to divulge any information about what they are doing." "In a nutshell, what this program describes is very low nitrogen and very high sulfur. This is different from, but clearly reminiscent of, thr program developed from the work of Dr. Goss at WSU [Washington State University]. It is very clearly oriented towards growing bentgrass." Predicts that under the program "golf courses that are predominantly annual bluegrass will eventually see serious problems with anthracnose, Fusarium patch, nematodes and any other diseases that affect annual bluegrass in our region. This may even happen during the first year of use and will become increasingly severe as time passes. Golf courses that are predominantly bentgrass on sand-based rootzones may be okay, at least until the nitrogen reserves in the rootzone are depleted to the point where growth is seriously impaired. At some point, dollar spot may become a serious issue, requiring increased use of fungicides. Turf in cold winter areas will go dormant earlier in fall and be late to green up in spring. Turf damage from wear on greens with limited hole locations will be slow to recover, resulting in very thin turf. I suspect there will be other problems, but I don't know yet what they will be." Concludes that "i encourage all of you to think long and hard before mortgaging the health of your putting greens on any program that promises to solve all of your problems.,,Before you launch off on something radically different from your current tried-and-true program, test it out thoroughly on your nursery green." |
