Management considerations | ||||
Gradational soil profiles allows water and gas (air) to move without physical limitations, but remains dependent on any chemical or depth restrictions. Deep sandy soils generally have poor plant water/nutrient holding capacities. These soils may be hydrophobic (in conjunction with organic coatings) when dried out, taking time to reabsorb moisture. These soils do however drain rapidly. |
