EFFECTS OF MICRO SITES AND AMENDMENTS ON NEAR SURFACE SOIL TEMPERATURE AND VOLUMETRIC WATER CONTENT TO ENHANCE REVEGETATION
DownloadFall 2015
Land reclamation requires successful germination, emergence and establishment of desired plant species. Seed and micro sites, often lacking in disturbed ecosystems, can be limiting factors for germination and plant establishment. Micro sites, or safe sites, are required to reduce or prevent soil...

Effects of Mineral Nutrition and Iron Supply on Growth and Physiological Responses of Selected Boreal Plant Species to Root Zone pH
DownloadSpring 2018
High soil pH can aggravate the effects of water deficit stress, inhibit root growth, and reduce the availability of essential elements to plants, especially iron. Iron deficiency can severely decrease plant growth and yield and result in plant mortality. In my study, I examined the effects of...

Identification of salt- resistant tree species and genotypes is needed for rehabilitation of lands affected by salinity in Mexico. This dissertation consists of four studies for analyzing the responses of Pinus leiophylla seedlings to salt. In the first study, resistance to salt stress was...

Effects of Non-segregated Tailings, Nitrogen, Phosphorus and Elemental Sulphur on Growth of Plants in Oil Sands Reclamation Soils
DownloadSpring 2021
Oil sands mining in northeastern Alberta, Canada, has disturbed large areas of the northern boreal forest. These disturbed areas must be reclaimed to forest ecosystems with equivalent land capability after mining closure. The extraction of bitumen is carried out with recycled hot water containing...

Red alder (Alnus rubra [Bong.]), is the most common hardwood species along the Pacific Northwest coast and is widely distributed as a component of mixed stands with conifers on highly productive sites. It is also a strong competitor in young conifer stands and rapidly overtops associated juvenile...

Effects of Root Zone pH, Calcium and Phosphorus Supply on Selected Boreal Forest Plant Species
DownloadSpring 2015
Soil pH is among the major environmental factors affecting plant growth. In the reclaimed areas following open-pit oil sands mining in northeastern Alberta, Canada, the pH of reclaimed soil is commonly higher than 8.0. The optimum range of soil pH for growth and the tolerance of pH extremes...

The boreal forest is a major ecosystem in Alberta, subject to a number of anthropogenic disturbances such as oil and gas extraction. Prior to disturbance, top soils are salvaged for use in future reclamation projects; however, a large portion of this soil ends up in stockpiles, undergoing changes...
