What are thatch levels and why do they matter in golf?
Thatch levels have an important role to play in the quality of a playing surface, despite not being entirely understood by the majority of golfers.

What is thatch in grass?
What is thatch? Thatch is a layer of organic material, such as dead grass stems and roots, which forms between the grass surface and the soil beneath. This material contains lignin, a compound which slows down its natural breakdown within the turf.
What is the effect of thatch on the Greens?
These large accumulations of organic matter (thatch) were having a dramatic effect on the playability of the greens, especially in periods of heavy rainfall. This, coupled with footfall, resulted in uneven, foot-marked greens that were not conducive to producing a quality putting surface.
How deep should thatch be on a golf green?
A shallow layer of thatch will also protect the new growth of grass shoots. However, any depth of thatch above a quarter of an inch is detrimental, particularly on golf greens where a firm fast surface is desired.

What is thatch in Bermuda grass?
Thatch is defined as the living and non-living material located between green turfgrass leaves and the underlying soil. Bermudagrass turf in the Florida Region accumulates a large amount of organic matter, and it is best to use the terms "thatch" and organic matter or "mat". In this case, thatch is the layer of turfgrass stems located just below the green leaf canopy and mat is the dark organic material located under thatch. Some thatch and mat is necessary for surface resiliency and nutrient retention, but excessive thatch can cause major issues with playability and turf health.
Why are my Bermuda grass greens saturated?
It causes greens to remain saturated in the upper rootzone, reducing oxygen uptake and encouraging root decline.

What is compost de thatcher?
The Compost De-Thatcher is a high-quality fertiliser made of a unique blend of slow-releasing nitrogen, naturally occurring soil digesting microbes, and powerful enzymes that work in breaking down components of organic matter in thatch . These elements work together to break down the high ratio of lignin and cellulose fibres in turfs. Additionally, the specific microbes formulated into the Compost De-Thatcher produce significant quantities of protease and cellulase that digest protein found in thatch and other organic compounds. Bacillus is also among the beneficial bacteria which produces cellulase, amylases, lipases, xylanases, and pectinases. They aid in breaking down organic matter into valuable nutrients. The right fertiliser can maintain the right amount of thatch, keeping your overall golf course healthy. Interested to know more about how the Compost De-Thatcher can benefit your golf course? Please contact Putra Fajar ([email protected]) for more details.

Why do you aerate greens?
Aeration comes in when soils are heavily compacted or the turf is thick with thatch. The greens get punched and sanded, and the sand is worked into each aeration hole to improve air and water flow, giving the roots a better chance to drink and breathe. There is, of course, plenty more to the science of sanding.
Why is sanding greens important?
