Who are the players in your turf?
A study by Clemson University found greater thatch control in turf systems using Soil ProVide.
Clemson University performed a research trial on thatch control for turf systems. It is known that moderate levels of thatch and soil organic matter are desirable for turfgrass systems due to enhancement of soil structure, improvement of nutrient retention, and increase water holding capacity (especially in sandy soils). However, in many high maintenance turf situations, plant tissue is produced faster than broken down, resulting in thatch and organic matter accumulation. Excessive thatch can cause decreased playability of turf surfaces, mower scalping, increased disease pressure, reduced pesticide efficacy, and poor water infiltration.
The objective of this research was to evaluate various chemical/biological thatch control programs using Soil Provide, and industry standards molasses and Thatch-X, to determine their effect on thatch and organic matter decomposition. Conducted from fall 2011 to late summer 2012, the study objective was to evaluate chemical thatch control in a Tifway bermudagrass fairway. The experiment was located in a golf course fairway at Sage Valley Golf Club in Graniteville, South Carolina, where excessive thatch accumulation has occurred after numerous years of overseeding with perennial ryegrass. At research completion, Soil ProVide had significantly shallower thatch depths (43.4mm) than the untreated control (60.3mm). Soil ProVide decreased the thatch depth by 2mm, and reduced organic matter weight by 45 grams.
The conclusion: a Soil Provide program has great potential for turf thatch control, as this program lowered thatch depths and organic matter weights than the untreated control, and also significantly reduced thatch depths and organic matter weights for the duration of the study.
