Salinity Distribution in the Municipal District of Provost

The M.D. of Provost has 1 851 saline seeps which occupy a total of 16 099.20 ha (39 768 ac), representing 4.3% of the M.D.'s total area. The visibly saline areas have such high salinity levels that annual crops cannot be grown and forage crops have significantly reduced yields. Often the lands surrounding the visibly saline areas are also weakly saline, resulting in reduced yields especially for salt-sensitive crops.

Salinity type	Number of seeps	Area (ha)	Percent of total saline area
Contact/slope change	338	670	4.2
Outcrop	15	33.7	0.2
Depression bottom	1 448	13 828.4	85.8
Coulee bottom	49	1 565.9	9.8
Artesian	1	1.5	0
Slough ring	4	39.83	0.3
Total	1 851	16 099.5	100.0

Depression bottom salinity is occupies the greatest area (85.8% of all saline land in the M.D.), followed by coulee bottom salinity (9.8%), contact/slope change salinity (4.2%), outcrop salinity (0.2%) and artesian salinity (0.009%). There is no evidence that slough ring salinity occurs in the M.D. Also, there are no irrigated lands in the M.D., thus there is no irrigation-related salinity.
