This book was released on 1993 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous studies have documented the soil disturbance effects of ground-based harvesting systems. Biomass harvesting, in the form of the additional recovery of woody materials normally left on site, has the potential for increasing the levels of soil disturbance. The objective of this study was to document the impact of biomass harvesting by rubber-tired skidders on soils, namely soil disturbance and surface soil erosion. An increase in soil disturbance in the form of skid trails, skidroads, and deep and very deep gouges was observed on the biomass harvested plots compared to the conventionally harvested plots. Erosion bridges indicated more soil movement on the biomass than the conventional plots. Soil erosion volumes trapped behind sediment dams located at the base of the plots were greater on the biomass plots (average of 0.38 m3 over 1.77 years) than on the conventional plots (average of 0.22 m3). However, the unharvested plots also recorded accumulation of material where in fact no mineral soil erosion occurred (average of 0.15 m3). This was the result of vegetation growth and decay and the accumulation of organic matter. Adjusted average erosion values of 0.78 m3/ha/year for the biomass plots and 0.37 m3/ha/year for the conventional plots are comparable to data obtained from studies conducted on clearcut and burned sites in the Oregon Cascades. These erosion figures are considered moderate and numerous site factors help explain this observed response. Rainfall simulation experiments conducted at the site indicated that infiltration rates on skidroads and fireguards are generally greater than 1.5 cm/hour. Rainfall intensities (15 minute duration) that exceed 1.5 cm/hour are expected to occur with a return period of about 1 year at the study site. Spring snow melt rates may exceed infiltration capacities especially along compacted, low infiltration areas such as skidroads. Some overland flow and surface soil erosion is expected to occur elsewhere under similar conditions as those found at the study site. Recommendations are given regarding the measurement techniques used in this study.

Carmean and published by Thunder Bay : Ontario Ministry of Natural Resources, Northwest Science and Technology. This book was released on 1996 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is directed toward the evaluation and classification of forest land in north-west Ontario for timber production, with the primary objective of providing tools for a quantitative evaluation of the capability of forest land to produce tree growth. The first few chapters describe methods for estimating forest site quality, including direct methods based on measuring site index from standing trees and indirect methods based on soil and topographic features. The manual also provides a complementary framework showing relationships between site quality, forest-landscape classification, and growth and yield. This framework accommodates other land values that are in addition to timber production. A final chapter suggests how application of this integrated framework can produce a diversified forest landscape having a spectrum of management intensities, a variety of site-specific silvicultural practices, and a variety of forest land values and uses.

Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.
