Management considerations | ||||
Deep sandy soils generally have poor plant water/nutrient holding capacities and can be extremely vulnerable to wind, and sheet and rill erosion. These soils may be hydrophobic (in conjunction with organic coatings) when dried out, taking time to reabsorb moisture. They do however drain rapidly. Ferruginous and Ferromanganiferous nodules (ironstone), concretions and pans can restrict root penetration and limit available water holding capacity where there are sufficient amounts, often forming a discontinuous or continuous pan where concentrated (>50%). They are also an indication of a periodic waterlogging. |
