Use of land resource data to target degradation-prone low capability lands in Saskatchewan

Abstract

Three approaches were investigated for estimation of the extent and location of highly erodible cultivated low capability lands in Saskatchewan. The three methodologies discussed include a map overlay of generalized soils and land use data, the manipulation of a computerized soil database, and manipulation of Saskatchewan Assessment Management Agency agricultural database. Correlations have been developed that allow the targeting of such lands to the quarter section level. Total extent was variously estimated at 1.1 to 7.2 million acres. The geographic distribution is concentrated (58 %) in seven Agricultural Extension Districts primarily in the southwest and west central regions, although all areas of the province were documented to have some marginal land. The use of the data by both agricultural and non-agricultural agencies in the planning of programs for conversion of lands permanent cover is discussed.
