Kuma and Rago soils do not have an albic horizon, are well drained, and have polygenetic profiles. Tomek soils are well drained, do not have an albic horizon and are higher in the landscape. Poorly drained and very poorly drained. These soils are saturated in the upper part of the solum for more than 30 consecutive days during the growing season. They are ponded for long and very long durations during the growing season.
Permeability is very slow and water loss is mainly by evaporation.
Runoff is ponded. Most of the acreage is in pasture. Annual weeds and aquatic plants are the most common plants. Some areas are being artificially drained for farming, but crop production is low. Some areas are farmed, without drainage, but harvest of crops is rare due to ponding and droughtiness when water is gone.
