Description

Agricultural soils are a source as well as a sink for C. Proposed is a model to assess CO2 emissions from agricultural soils for each Ecodistrict in the white area of Alberta. Results indicate that C emissions vary with cropping and tillage systems and range from 140 to 669 kg CO2 ha-1 y-1. Annual CO2 emissions from conventional till are two times higher than from zero till systems. Paper presented to the 37th Annual Alberta Soil Science Workshop, February 22-24, 2000, Medicine Hat, Alberta.

Description

The process of salinization is slow and variable. This underlines the need for long-term determination of changes in salinity and the need for appropriate methodologies. The most reliable historical data covering large areas is aerial photography. A series of air-photos were used to determine the extent of visible salinity for each decade since 1950 for 89 sites in the Brown, Dark Brown and Black soil zones in Alberta. Three ground water flow systems were looked at including: local, regional and irrigation. Paper presented to the 37th Annual Alberta Soil Science Workshop , February 22-24, 2000, Medicine Hat, Alberta.

Historical trends in soil available phosphorus across Alberta

Description

Alberta soil test results from 1963-67 and 1993-97 were analyzed to determine levels of available soil phosphorous across Alberta on an ecodistrict basis and to determine changes in available soil... More ≫

Description

Alberta soil test results from 1963-67 and 1993-97 were analyzed to determine levels of available soil phosphorous across Alberta on an ecodistrict basis and to determine changes in available soil phosphorous that occurred over time. Soil available phosphorous for dryland annual crops did not change in 20 ecodistricts, increased in 15 ecodistricts, and decreased in 27 ecodistricts. Soil available phosphorous for dryland perennial crops did not change in 24 ecodistricts, increased in 7 ecodistricts, and decreased in 9 ecodistricts. Paper presented to the 37th Annual Alberta Soil Science Workshop, February 22-24, 2000, Medicine Hat, Alberta.

Description

This is the first soil survey report to deal solely with an area that is irrigated or proposed for irrigation development. The three soil maps that form part of this report show the kind and location of the various soil and topography types. The report describes the soil types, gives analytical data of representative profiles, and gives the average rating of each soil type. Three appendices cover problems related to land levelling, to salinity and drainage, and to fertility and management.
