Book Description
Management Strategies for Sustainable Cattle Production in Southern Pastures is a practical resource for scientists, students, and stakeholders who want to understand the relationships between soil-plant interactions and pasture management strategies, and the resultant performance of cow-calf and stocker cattle. This book illustrates the importance of matching cattle breed types and plant hardiness zones to optimize cattle production from forages and pastures. It explains the biologic and economic implications of grazing management decisions made to improve sustainability of pastures and cattle production while being compliant with present and future environmental concerns and cattle welfare programs. - Documents the effects of cattle grazing on greenhouse gas emissions and carbon footprints - Discusses strategies to enhance soil fertility, soil health, and nutrient cycling in pastures - Provides information on the use of stocking rates, stocking strategies and grazing systems to optimize cow-calf production of weaned calves and stockers. - Presents innovations in cattle supplementation and watering systems to minimize negative impacts on water and soil health - Includes methods for weed control to maintain pasture condition and ecosystem stability - Describes management strategies to integrate cattle operations with wildlife sustainability

Book Description
The theme of this book is a far reaching one and should attract great interest, both in industrialized as well as in less developed countries. Although the question of climate change and its effects on soil productivity is overshadowed by so many current events, it is almost certain that this subject will remain on the international agenda for the years to come; not only as science and research are concerned but also in relation to development policies, agricultural policies and others, especially since poor, rich, developed and developing countries are equally threatened by these problems.

Book Description
The long-awaited second edition of this classic textbook expands on the first edition to include advances made in the last four decades, bringing the topic completely up to date. The book addresses critical issues such as whether humanity can feed itself, and whether it can do so in environmentally sound and sustainable ways. Written from agronomic, environmental, and ecological standpoints, the textbook employs a multidisciplinary approach, including policymaking and plant genetic improvements, as well as ecosystem services, climate change, biodiversity, sustainability and resilience. New chapters in this second edition focus on organic carbon in soil, soil biology, soils in relation to livestock production and forestry, and agroforestry. The new edition will again be the go-to textbook for courses on tropical soils, and a reference textbook for soil and agricultural scientists and development professionals working in the tropics.

Book Description
This integrated collection describes the importance of forage legumes for pasture development and improvement in the tropics and subtropics. Leading agronomists review the magnitude of the need for pasture improvement; tropical and subtropical soil and climate environments; reports of the successful use of legumes in pasture development in a wet and a dry tropical environment; and the scope of the problem in terms of area to be developed and development logistics required. Three legume genera, Centrosema, Desmodium, and Stylosanthes, are discussed in detail--information is presented on taxonomy, adaptation, distribution, productivity, and usefulness--and considerable emphasis is placed on Rhizobium germplasm resources for these genera. A concluding section of technical essays addresses special considerations in using tropical legumes in pasture development and presents a coordinated multidisciplinary approach to legume exploration and evaluation.
