So far on our investigation into soil texture we’ve discussed the problems of building sand castles, why you shouldn’t let the Treasurer buy sand for you and a few other less important details like the complexity of sand, soil formation, particle size distribution, macro and micro soil porosity and we finished last time by looking at the famous Soil Texture Triangle. It will indicate the percentage of sand, silt, and clay present in the soil. In relatively recent times, say from the 1970’s onwards, greenkeepers, bowls clubs and golf clubs have become more than a little obsessed with sand. Larger particles will have less surface area per volume of soil. The two commonest ones are that for the USDA (which has 12 soil texture classes) and SSEW (which has 11 soil texture classes).
