Field and laboratory data are critical to the understanding of the properties and genesis of a single pedon, as well as to the understanding of fundamental soil relationships based on many observations of a large number of soils. Key to the advancement of this body of knowledge has been the cumulative effort of several generations of scientists in developing methods, designing and developing analytical databases, and investigating soil relationships based on these data. Methods development result from a broad knowledge of soils, encompassing topical areas of pedology, geomorphology, micromorphology, physics, chemistry, mineralogy, biology, and field and laboratory sample collection and preparation. The purpose of this manual, the "Soil Survey Field and Laboratory Methods Manual, Soil Survey Investigations Report (SSIR) No. 51," is to (1) serve as a standard reference in the description of site and soils sampling strategies and assessment techniques and (2) provide...

This book explores the importance of soil health in croplands, rangelands, pasturelands, and gardens, and presents new methods and technologies for assessing soil dynamics and health in these different land types. Through perspectives of agriculture, soil management, and ecological sustainability, the book provides accurate and up-to-date information on soil health assessment and maintenance that is often missing from current literature on conservation and environmental management and preservation. The book is written in a clear and concise format, and will appeal to non-scientists interested in soil health, as well as professional farmers, ranchers and gardeners. The book begins by discussing soil health from a historical perspective, and in terms of how it is covered in the news currently. Then the author addresses the ecological implications of soil health in farming, ranching and gardening, and comprehensively details the physical, chemical and biological properties of soil as they apply in various land types. The book then examines soil health assessment using new diagnostic and analytic technologies, and how these new innovations will be necessary going forward to maintain and improve soil health.

This technical report examines the connection between climate change and livestock, focusing on the impacts on livestock production systems. The study explores various methodologies from the literature and analyses their application in a practical test case in the Lao People's Democratic Republic. The assessment estimates direct and indirect effects of climate change on the livestock sector by focusing on three main methodologies retrieved from the scientific literature and applied to the specific case of Lao People's Democratic Republic. The results reveal significant effects of climate change on cattle and buffaloes, the main ruminant species in the country. The findings showed significant losses in Lao People's Democratic Republic production due to heat stress affecting dry matter intake. For instance, under the representative concentration pathway 2.6 scenario, the analysis estimated a 19 percent loss in meat production and a 18 percent loss in milk production by 2085. The thermal-humidity index, used as a proxy for milk production estimation, yielded similar results. On a positive note, the study revealed that the carrying capacity and the number of potential livestock units are expected to increase from 2020 to 2080, counteracting some of the negative effects of climate change induced by heat stress. The proposed methodologies can be combined to provide a comprehensive understanding of the current and future state of the livestock population and production. While the effects may vary in different regions and production systems, the report emphasizes the importance of implementing strategies to mitigate climate change impacts. Overall, this report provides crucial information for policymakers and agencies involved with the livestock sector to guide interventions and address the challenges posed by climate change.

This deft and thorough update ensures that The Wildlife Techniques Manual will remain an indispensable resource, one that professionals and students in wildlife biology, conservation, and management simply cannot do without.

"This book contains a compilation of offered papers presented at the main congress of the XX International Grassland Congress held in University College Dublin, Ireland from 26 June to 1 July, 2005. It is complemented by six other books arising from the XX IGC as listed on the back cover: the book of invited papers from the main congress and five books containing the proceedings of five satellite workshops held immediately after the main congress at locations in the UK and Ireland (Aberystwyth, Belfast, Cork, Glasgow and Oxford). The workshops were designed to facilitate more in-depth presentations and discussions on more specialised topics of worldwide significance. The main congress brought together scientists from many disciplines, policy makers, consultants and producers involved directly in grass production and utilisation, as well as people in associated industries. They discussed issues around the theme of the congress, Grasslands : a Global Resource. The congress programme was organised around three main thematic areas: Efficient Production from Grassland Grassland and the Environment Delivering the Benefits from Grassland"
