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)
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.

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
