  "definition": "Aridisols, as their name implies, are soils in which water is not available to mesophytic plants for long periods. During most of the time when the soils are warm enough for plants to grow, soil water is held at potentials less than the permanent wilting point or has a content of soluble salts great enough to limit the growth of plants other than halophytes, or both. There is no period of 90 consecutive days when moisture is continuously available for plant growth. The concept of Aridisols is based on limited soil moisture available for the growth of most plants. In areas bordering deserts, the absolute precipitation may be sufficient for the growth of some plants. Because of runoff or a very low storage capacity of the soils, or both, however, the actual soil moisture regime is aridic.",
