Download or read book Mulches Aid in Regenerating California and Oregon Forests written by Philip M. McDonald and published by . This book was released on 1990 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of mulches as a reforestation tool in Oregon and California began primarily in the late 1950's. Many types of mulches were tried including sheets of plastic, newspaper, and plywood; various thicknesses of bark, sawdust, sand, and straw; sprayed-on petroleum resin; and even large plastic buckets. Most proved to be ineffective, costly or both. Early trials tended to use small, short-lived materials that aided conifer seedling survival, but not growth. Compared to other weed-control techniques available at the time, mulches were rather expensive. Current trends are to apply longer-lived, somewhat larger mulches of mostly sheet materials made of reinforced paper, polyester, or polypropylene. When the various costs of mulching (material, installation, and maintenance) are totalled, the overall cost of the technique continues to be high. Recently, new mulch materials of polyester, polypropylene, or combinations of both have allowed silviculturists to consider large, durable mulches (10 by 10 feet or 3 by 3 m) for enhancement of growth (not just survival), and to control plants with stiffer stems.

Book excerpt: Crop loss due to weeds has challenged agricultural managers since man began to develop the first farming systems. In the past century, however, much progress has been made to reduce weed interference in crop settings through effective yet mostly non-sustainable weed control strategies. With the commercial introduction of herbicides during the mid-1900's, advancements in chemical weed control tactics have provided efficient suppression of a broad range of weed species for most agricultural practices. Currently, with the necessity to design effective sustainable weed management systems, research has been pushing new frontiers on investigating integrated weed management options including chemical, mechanical as well as cultural practices. Author contributions to Weed Science present significant topics of research that examine a number of options that can be utilized to develop successful and sustainable weed management systems for many areas of crop production

Download or read book Paper and Composites from Agro Based Resources written by Roger M. Rowell and published by CRC Press. This book was released on 1996-10-15 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable development is an important concept underlying many of today's renewable resource policies. Agro-based resources, such as wood, make up a significant portion of modern renewable resources. While probably the most familiar example, wood is only one type of agromass in the vast world of photosynthetic resources. Paper and Composites from Agro-Based Resources explores the great number of options available for producing paper and composites. Using sound ecosystem management principles, the book discusses strategies for obtaining fiber from plant-based resources including agricultural crops and residues, grasses, and recycled agro-based resources, in addition to wood.

Download or read book Silviculture written by Ralph D. Nyland and published by Waveland Press. This book was released on 2016-05-13 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

Download or read book Ecological Intensification of Natural Resources for Sustainable Agriculture written by Manoj Kumar Jhariya and published by Springer Nature. This book was released on 2021-03-07 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological intensification involves using natural resources such as land, water, soil nutrients, and other biotic and abiotic variables in a sustainable way to achieve high performance and efficiency in agricultural yield with minimal damage to the agroecosystems. With increasing food demand there is high pressure on agricultural systems. The concept of ecological intensification presents the mechanisms of ensuring high agricultural productivity by restoration the soil health and landscape ecosystem services. The approach involves the replacement of anthropogenic inputs with eco-friendly and sustainable alternates. Effective ecological intensification requires an understanding of ecosystems services, ecosystem's components, and flow of resources in the agroecosystems. Also, awareness of land use patterns, socio-economic factors, and needs of the farmer community plays a crucial role. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape. The editors critically examined the status of ecological stress in agroecosystems and address the issue of ecological intensification for natural resources management. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into the approaches that can be put in practice for poly-cropping systems and landscape-scale management to increase the stability of agricultural production systems to achieve ‘Ecological resilience’. It further discusses the role of farmer communities and the importance of their awareness about the issues. This book will be of interest to teachers, researchers, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, agronomy, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be a useful read for green future.

Book excerpt: In August 20-23, 2004, a conference was held in Kamilche, WA, with the title S2Productivity of Western Forests: A Forest Products Focus. S3 The meeting brought together researchers and practitioners interested in discussing the economic and biological factors influencing wood production and value. One of the underlying assumptions of the meeting organizers was that management activities would be practiced within a framework of sustaining or improving site productivity; thus, several papers deal with methods to protect or improve productivity or discuss new studies designed to test the effects of various practices. This proceedings includes 11 papers based on oral presentations at the conference, 3 papers based on posters and 2 papers describing the Fall River and Matlock Long-Term Site Productivity study areas visited on the field tours. The papers cover subjects on forest harvesting activities, stand establishment, silviculture, site productivity, remote sensing, and wood product technologies.
