They are deep, moderately to well drained, nearly level soils on low terraces and flood plains. Permeability is moderately slow and the available water capacity is high. Runoff is very slow to slow and the hazard of erosion is slight. These soils are not prone to saline seep and are well suited to irrigation. Irrigation enhances crop cover during the growing season and provides more protection from wind and water erosion.
Irrigation also increases plant residues returned to the soil.
Soil structure is improved, microbe populations benefit from the added food source, and nitrogen fertility is enhanced. Assess whether the proposed project would result in the establishment or spread of noxious weeds. There will be some disturbance to the vegetative cover during the construction of the pump site, pipeline and borders. The majority of this area will be re-seeded into crops. The areas that will not be seeded in crops should be re-seeded, preferably with native grasses, to discourage the establishment of noxious weeds.
