This book was released on 2015 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest floor mineral soil mix (FMM) and peat mineral soil mix (PMM) are cover soils commonly used for land reclamation post open pit oil sands mining in northern Alberta, Canada. While in such land reclamation practices the organic matter comes from the peat material salvaged before land disturbance, coarse woody debris (CWD) can be used as an additional organic matter amendment for land reclamation. Effects of cover soil type (FMM vs PMM) and CWD (near vs away from CWD) on microbial community level physiological profile, extracellular enzyme activities, greenhouse gas emission rates and nitrogen (N) transformation rates were determined between 4 and 7 years after reclamation to assess whether applying CWD can facilitate land reclamation. Soil sampling and analyses were conducted and greenhouse gas emission rates were measured monthly during growing seasons within 5 cm from CWD and more than 100 cm away from CWD. Monthly in situ soil incubation was conducted and plant root simulators were incubated to assess net N transformation rates and N supply rates, respectively. A laboratory incubation experiment using 15N isotopic dilution was conducted to evaluate the effect of CWD leachate on gross and net N transformation rates. The soil microbial community level physiological profile was changed by CWD in FMM (p

Book excerpt: At 170 billion barrels, Canada's Oil Sands are the third largest reserves of developable oil in the world. The Oil Sands now produce about 1.6 million barrels per day, with production expected to double by 2025 to about 3.7 million barrels per day. The Athabasca Oil Sands Region (AOSR) in northeastern Alberta is the largest of the three oil sands deposits. Bitumen in the oil sands is recovered through one of two primary methods - mining and drilling. About 20 per cent of the reserves are close to the surface and can be mined using large shovels and trucks. Of concern are the effects of the industrial development on the environment. Both human-made and natural sources emit oxides of sulphur and nitrogen, trace elements and persistent organic compounds. Of additional concern are ground level ozone and greenhouse gases. Because of the requirement on operators to comply with the air quality regulatory policies, and to address public concerns, the not-for-profit, multi-stakeholder Wood Buffalo Environmental Association (WBEA) has since 1997 been closely monitoring air quality in AOSR. In 2008, WBEA assembled a distinguished group of international scientists who have been conducting measurements and practical research on various aspects of air emissions and their potential effects on terrestrial receptors. This book is a synthesis of the concepts and results of those on-going studies. It contains 19 chapters ranging from a global perspective of energy production, measurement methodologies and behavior of various air pollutants during fossil fuel production in a boreal forest ecosystem, towards designing and deploying a multi-disciplinary, proactive, and long-term environmental monitoring system that will also meet regulatory expectations. Covers measurement of emissions from very large industrial sources in a region with huge international media profile Validation of measurement technologies can be applied globally The new approaches to ecological monitoring described can be applied in other forested regions

Available in PDF, EPUB and Kindle. Book excerpt: Identifying, interpreting, and managing soil constraints are major challenges, especially when multiple constraints occur in the same soil at various depth zones. Although amelioration tools and strategies are available to manage some of these constraints, field adoption of these technologies is a major challenge to the farming community. Soil Constraints and Productivity helps in identifying and understanding soil constraints, focusing on management practices to alleviate problems associated with these restrictions, and their impacts on crop productivity. Soil Constraints and Productivity aims to: Describe various strategies suitable for mitigating soil constraints Provide data on cost-benefit analysis of managing soil constraints Provide case studies of managing soil constraints to increase productivity Soil is essential for the doubling of major grain production proposed to be necessary to avoid major food security collapses in the future. This book will be a key resource for soil and environmental scientists, farmers, students majoring in agricultural and environmental sciences, and crop consultants.

Available in PDF, EPUB and Kindle. Book excerpt: Spoil to Soil: Mine Site Rehabilitation and Revegetation presents both fundamental and practical aspects of remediation and revegetation of mine sites. Through three major themes, it examines characterization of mine site spoils; remediation of chemical, physical and biological constraints of mine site spoils, including post mine-site land-use practices; and revegetation of remediated mine site spoils. Each theme includes chapters featuring case studies involving mine sites around the world. The final section focuses specifically on case studies with successful mine site rehabilitation. The book provides a narrative of how inert spoil can be converted to live soil. Instructive illustrations show mine sites before and after rehabilitation. The purpose of this book is to provide students, scientists, and professional personnel in the mining industry sensible, science-based information needed to rehabilitate sustainably areas disturbed by mining activities. This book is suitable for undergraduate and graduate students majoring in environmental, earth, and soil sciences; environmental and soil scientists; and mine site environmental engineers and regulators.

Download or read book Quantifying the Influence of Soil Prescriptions on Ecosystem Processes in Reclaimed Forests of Varying Age in a Post Oil Sands Landscape in the Athabasca Oil Sands Region Alberta Canada written by Tyler Matthew Prentice and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Athabasca Oil Sands Region (AOSR) in northern Alberta, Canada contains ~4800 km2 available for surface mining, and as of 2017 ~767 km2 had been disturbed for oil sands operations. The Alberta government requires this land to be reclaimed back to an equivalent capacity following the closure of mining operations. This includes the reclamation of upland forests, which serve vital ecosystem functions to the region. These functions are influenced by the cover soils used while reclaiming these ecosystems as they are designed to provide sufficient water and nutrients for the vegetation being planted. There are two different cover soils typically used in reclamation, peat mineral mix (PMM) and forest floor material (FFM), while there have been studies examining the differences between them some of the results are inconsistent. This research aims to further the understanding of how differences in cover soils used can influence the moisture and nutrient regimes of reclaimed forests, and how these processes change as vegetation develops. Seven sites in the AOSR that varied in age, cover soil, and vegetation prescription were used for this study. Differences in soil physical properties were assessed and compared to changes in volumetric water content throughout the growing season to assess their impact on water regimes. Once the relationship between soil physical properties and water regimes were established the nutrient regimes of the sites were assessed through the in situ buried bag method. Similarly, to volumetric water content, nutrient mineralization rates were compared to soil physical properties to assess their impact on the nutrient regimes of the sites. Once the relationship between soil prescription and the water and nutrient regimes were established, how vegetation development can impact these processes could be determined. Soil texture was found to be the dominant driver of water regimes at reclaimed sites, having a greater influence than topographical variables. This led to some sites being re-vegetated incorrectly, which can lead to increased time for vegetation to become established and a potentially longer period before sites can become certified. Furthermore, the type of cover soil and mineral layer used were found to influence soil water regimes, with prescriptions using FFM having higher infiltration rates then PMM, while fine tailings sand mineral layers were more likely to result in water limited systems than overburden material. In contrast the impact soil prescriptions used in reclamation had on nutrient regimes was much smaller then hypothesized. The lack of differences observed between FFM and PMM suggests that five years post-revegetation any initial benefits to the nutrient regimes of the soil will no longer be present. The only parameter that seemed to influence nutrient mineralization rates was silt content, where sites with a higher silt content typically had a slight increase in N, NH4+, and NO3- mineralization. In contrast, litter mineralization rates followed a similar trend to what would typically be observed in natural boreal forests, with broadleaf sites having higher P mineralization rates while NH4+ and N were unrelated to vegetation type. These findings suggested that while soil physical properties have a significant influence on the water regimes of reclaimed sites, they have little impact on nutrient regimes five years post-revegetation. Instead vegetation inputs are the dominant control on nutrient availability. However, soil water regimes drive what vegetation can become established on reclaimed sites. Therefore, when attempting to predict the nutrient regimes of a site it is important to consider the impact soil properties will have on water regimes and how that may impact vegetation colonization, which will ultimately govern the nutrient mineralization rates.

This book was released on 2012-09-20 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boreal ecosystems contain one-third of the world's forests and stored carbon, but these regions are under increasing threat from both natural and anthropogenic disturbances. Written by leaders from the forefront of private, public and academic sectors, Restoration and Reclamation of Boreal Ecosystems emphasises a broad, conceptual approach to the specific application of empirical research into development planning, restoration and modelling of these ecosystems. The importance of this is highlighted at a time of global climate change, as these ecosystems act as carbon sinks. There is a focus on the reclamation of exploited ecosystems from a holistic standpoint, ranging from environmental and edaphic variables to the restoration of keystone flora. Recent advances in quantification of ecosystem services, such as habitat suitability and carbon storage modelling, are also detailed. The book contains case-studies which address how both historical and novel assemblages can provide ecosystem stability under projected climatic and land-use scenarios.
