total organic material

Measure exact topdressing effect, and requirement, by checking total organic material by depth.

I’ve updated the OM246 calculator to v2 with two substantial changes. One is an entirely new tab for unit conversions between different ways of expressing sand rates. I like mm. Others use kg/ha or tons/ha.

A substantial amount of organic material accumulated at the surface of a Tifdwarf bermudagrass putting green at Rota in the Northern Mariana Islands. I don’t recall if I read this exact statement, or if it occurred to me when I read something else about invigilation.

Everyone understands the segmentation of OM246 samples by depth. That is in the name of the test, after all. Most people understand that OM246 testing is a mass loss on ignition of all the material.

There’s a ton of work done to modify the soil organic matter of turfgrass surfaces. Fertilizer, water, and increased light will allow the grass to grow and naturally increase the organic matter in the soil.

These are some key things I’ve learned after studying soil organic matter (SOM) for a few years. This is about organic matter in the context of playing conditions—how a ball reacts when it hits the surface.
