Tapicito (NM) series.
Cameo soils: are usually dry in the moisture control section more than half the time in June.
Clarkelen soils: have colder air temperatures than 52 degrees and growing seasons shorter than 130 days.
Colorow soils: are moderately well drained with redoximorphic features.
Innacutt soils: have 10 to 25 percent mica in the control section.
Kornman soils: have over-thickened, nitrogen and phosphate enriched man-made surface horizons resulting from application of silty irrigation water over long periods of time.
Redbank soils: have hue of 7.5YR or redder.
Radnik soils: have hues of 2.5YR and 5YR in the control section, are driest in the soil moisture control section in
May and June and receive peak precipitation in July through September and December through February.
