Working with Dynamic Crop Models: Methods, Tools and Examples for Agriculture and Environment, 3e, is a complete guide to working with dynamic system models, with emphasis on models in agronomy and environmental science. The introductory section presents the foundational information for the book including the basics of system models, simulation, the R programming language, and the statistical notions necessary for working with system models. The most important methods of working with dynamic system models, namely uncertainty and sensitivity analysis, model calibration (frequentist and Bayesian), model evaluation, and data assimilation are all treated in detail, in individual chapters. New chapters cover the use of multi-model ensembles, the creation of metamodels that emulate the more complex dynamic system models, the combination of genetic and environmental information in gene-based crop models, and the use of dynamic system models to aid in sampling. The book emphasizes both understanding and practical implementation of the methods that are covered. Each chapter simply and clearly explains the underlying principles and assumptions of each method that is presented, with numerous examples and illustrations. R code for applying the methods is given throughout. This code is designed so that it can be adapted relatively easily to new problems.

Transgenic Plants, Volume 86, the latest release in the series Advances in Botanical Research, brings together information needed by many teachers, researchers and managers who have to consider biotechnology from a scientific or legal point-of-view. It presents authors who bring their long personal experience on a given subject. Although the subjects are technical in nature, the take-home message of each chapter is understandable by non-specialists.

Quantifying and Managing Soil Functions in Earth's Critical Zone: Combining Experimentation and Mathematical Modelling, Volume 142, the latest in the Advances in Agronomy series continues its reputation as a leading reference and first-rate source for the latest research in agronomy. Each volume contains an eclectic group of reviews by leading scientists throughout the world. Five volumes are published yearly, ensuring that the authors' contributions are disseminated to the readership in a timely manner. As always, the subjects covered are varied and exemplary of the myriad of subject matter dealt with by this long-running serial.

This comprehensive new soybean reference disseminates key soybean information to drive success for soybeans via 21 concise chapters. The text covers all aspects of soybeans, including genetics, breeding, quality, post-harvest management, marketing, utilization (food and energy applications), U.S. domestic practices versus foreign practices, and production methods.

This text is a synthesis of research in production and management since the inception of the discipline as an agricultural science in the 1930s. All the ecological regions are covered extensively, but the main emphasis is on the three biomes (grassland, savanna and karoo) which produce the bulk of the forage supporting the domestic livestock, conservation and the game farming industries. The book has an audience beyond the borders of South Africa in the grassland and savanna areas which stretch through southern and central Africa.;The text is aimed at students concerned with the management of natural ecosystems and also livestock producers and game ranchers who rely on the veld to feed their animals. The text throughout emphasizes the interpretation and application of research results to the practical situation.;All major aspects of veld production and management are covered in this book. It outlines the physiological and ecological principles on which management is based and which underpin the science. The book presents management options based on these underlying principles before dealing with recommended management procedures in each of the main ecological regions of the country.;The contributions to this book collectively represent a component of the expertise available on issues related to veld management in South Africa. They are veld and animal production researchers, conservation managers and planners working both at a practical level, closely in touch with livestock and game farmers, and at the more theoretical level as teachers at colleges and universities.

Landowners and managers, municipalities, the logging and livestock industries, and conservation professionals all increasingly recognize that setting prescribed fires may reduce the devastating effects of wildfire, control invasive brush and weeds, improve livestock range and health, maintain wildlife habitat, control parasites, manage forest lands, remove hazardous fuel in the wildland-urban interface, and create residential buffer zones.

In this practical and helpful manual, John R. Weir, who has conducted more than 720 burns in four states, offers a step-by-step guide to the systematic application of burning to meet specific land management needs and goals.

The latest edition of Animal Nutrition has been updated thoroughly to provide a clear and comprehensive introduction to the science and practice of animal nutrition. This classic, market-leading text is a trusted resource for undergraduates studying Animal Science, Veterinary Science, Agriculture, Biology and Biochemistry. It is supported by key experimental evidence throughout about modern advancements in animal food nourishment, composition of foods and feeding standards for dairy and beef cattle, sheep, pigs and poultry, horses, and cats and dogs. It is split into six main sections covering: The components of food; The digestion and metabolism of nutrients; Quantifying the nutrient content of foods: digestibility, energy and protein values; The nutrient requirements of animals; The nutritional characteristics of foods; and Animal products and human nutrition. Quantitative aspects of the subject are clearly explained and illustrated by worked examples. Problems have been added to all chapters to aid student learning and the appendices include solutions to all chapter-end numeric questions. This edition includes nutritional topics related to molecular biology, the environment, and companion animals - dog and cat nutrition has been expanded. Under nutrient requirements of animals, usage of novel foods such as insects has also been added. Chapter-end summaries and questions allow students to recap and test their knowledge of the chapter topic.
