Alkali Sacaton
(Sporobolus Airoides)
In areas characterized
by salt, alkali, drought, and occasional cloudbursts,
the occurrence and importance of this native grass is
well known to ranchers and rangemen alike. It has a wide
geographic range in the western United States. Alkali
Sacaton is a medium height, long-lived grass growing in
large course bunches. It is often found in almost pure
stands in valleys and flood plains. On these sites, particularly
where favored by a 1.2 to 2.4 m (4to 8 ft.) water table,
or frequent flooding, alkali sacaton produces an abundance
of forage. It is readily taken by cattle and horses during
the growing season, but with maturity becomes coarse and
tough, not curing out as highly palatable winter feed.
It is not necessarily confined to bottom lands, but it
is also found scattered or in small colonies over uplands
at medium elevations, especially on fine textured soils
of a calcareous gypsum nature.
The importance of this
species in range seeding and the reclamation of disturbed
sites on upland soils on alkaline bottom lands is well
recognized. The seed averages about 1,355,000 seed units
per .46kg (1lb) and is best planted through fine seed
boxes so it can be metered out at a rate of 1.1 to 1.7kg
PLS per hectare (1 to 1 1/2 lbs. PLS per acre). Depth
of planting should not be over 1.2 cm (1/2 inch) in the
fine-textured soils. Time of seeding will vary with the
location but should be early enough in the summer that
a period of warm soil temperatures will follow.
