Abstract/Contents:Discusses organic matter management, stating that it "is a key component of golf green maintenance. If the organic matter content is allowed to increase beyond approximately 12% by weight in the soil, it will start to dominate the soil physical properties of a roozone." Suggests that "usually, thatch management regimes for golf greens are not based on any objectively measured rootzone characteristics. Instead they tend to be based on historical practices, regional or district 'normal' practices, club programmes [programs] and budgets, and subjective rootzone observations. However, the measurement of total organic matter content of rootzones is a relatively simple exercise and information gained from this measurement can be used as an aid to formulating and monitoring thatch management programmes [programs]." States that the New Zealand (NZ) Sports Turf Institute "has been measuring the total organic matter content in a range of actual experimental turf rootzones, including golf greens, bowling greens and sports fields." Describes the measurement technique, stating that "for golf greens, the technique involves accurately sampling the rootzone in 20 mm [millimeter] deep incremental sections, submitting the samples to the NZ Sports Institute Turf Laboratory and requesting a total organic matter content determination." Reports that "findings indicated that in sand profiles, surface organic matter levels generally needed to be below 4.5% by weight to maintain adequate macroporosity and that organic matter values below a discrete thatch layer needed to be less than 4% and 3% for medium and fine sands respectively." Concludes that "measuring total organic matter content is a useful tool in sand-based golf green management. It takes some of the guess work out of renovation planning, helps to focus on the effectiveness of the treatments carried out and makes it easier to justify the requirement for these unpopular treatments."
