Field Capacity - an overview | ScienceDirect Topics

One of the most important attributes of sand dunes, resulting from the sand texture and the relatively big pore spaces, is low field capacity and a low value for soil moisture availability for plants (Figure 3), as well as a high rate of infiltration and leaching, resulting in the washing away of nutrient elements necessary for plant growth.
