Current requirements set out by the Alberta Government state that the goal of reclamation is to return mined land to a capability that
is equivalent or better than that which existed prior to mining. In preparation for coal strip-mine activity in the Lake Wabamun area,
Monenco Ltd. has been conducting agricultural field studies for TransAlta Utilities Corporation since 1977. These studies are conducted to quantify land productivity as a general indicator of land capability prior to mining for comparison to productivity on reclaimed land. A close association with rural community groups and land holders is maintained to ensure success and reduce interference with local farm activities.
Agricultural land is generally differentiated into major crop and soil types with the use of maps, aerial photographs and field surveys.
Field sites are selected for monitoring in relative proportion to the occurrence of the major crop and soil types within the study area.
Potential field sites are assessed on the basis of land use, uniformity of soil type and slope, and accessability. Sampling methodologies for major crop types such as pasture, hay and grain have been adapted over time to reduce variability encountered during field programs. A review of past research has been undertaken to develop a statistically valid methodology for , measuring productivity, with specific emphasis on pastureland monitoring.
