Measuring bulk density, electrical conductivity, fibre and moisture content in soil, sand and rootzone.

Bulk Density
ASTM Method : F1815-11
Electrical Conductivity
A measure of the concentration of soluble salts in soil/rootzone
(Expressed in µS/cm OR mS/cm)
Fibre Content
Gradation Index (D90/D10)
Gravel Compatibility with Sand/Rootzone
For single layer construction – from the BS Half Octave particle size distribution of the rootzone and the gravel, the D85 and D15 are determined and the bridging, permeability and gravel uniformity factors are calculated.
Moisture Content
Organic Matter (by Loss on Ignition)
ASTM Method : F1647-11a
Organics Analysis on Peat (pH, Organic Matter & Fibre Content)
ASTM Methods : D2974-07a (Organic Matter) and D2976-71 Re-approved 2004 (pH)
pH
ASTM Method : D4972-01 (Re-approved 2007)
Penetrometer Value & Crusting Potential
For bunker sands to assess the “fried-egg lie” and whether a crust will form on the surface of the sand when it dries out after wetting.

Relating Greens Organic Matter (LOI) to the Age of Golf Greens

This, our second article aims to investigate the relationship between the amount of organic matter in greens and the age of the greens. We hope this helps provide added perspective for managing your greens and provides an insight for members within your clubs.

The management of organic matter is one of the more complex maintenance and renovation tasks for Course Managers around the world, due to its immediate conflict to presenting smooth and fast putting surfaces.

European Turfgrass Laboratories (ETL) annually tests organic matter at 20mm segments for hundreds of golf courses all over the world, from over thousands of individual greens, from a variety of venues including courses with push-up greens, links style and USGA-type golf greens of all ages. This data helps Course Managers communicate better with their stakeholders and make more informed decisions. Read more

Organic Matter Testing #3

In this, our third article on organic matter, agronomist, Charles Henderson will cover the complex subject of its reduction. Organic matter, in general, is on the increase. Therefore, this makes the reduction of organic matter in greens, relevant to over 90% of us who are involved in managing golf (and bowling) greens, an extremely important subject. Read More.

Organic Matter Testing #2

In part two of our organic matter series, Charles Henderson discusses the relationship between moisture content and the organic matter accumulation in our greens. We will also look at how this affects some of the management decisions we make when trying to manage both moisture and organic matter content in our greens. Read full article
