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.

Recent advances in genetic engineering and in the chemistry and biochemistry of fruit and vegetables have radically changed our understanding of the mechanisms underlying these processes, and the potential for modification of the products themselves. This is the first book to examine these topics and address the role of fresh fruits and vegetables in a healthy diet and the prevention of cancer and coronary diseases. The main focus is on the secondary metabolites which are responsible for quality characteristics including color, aroma, and flavor, and their nutritional importance and role in the prevention of cancer and cardiovascular diseases. The book also explores how the post-harvest technological treatments to which these commodities are submitted can cause changes in secondary metabolism, with consequences for the quality of the product.
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.
Nano-Enabled Agrochemicals in Agriculture presents a targeted overview of the safe implementation of nanotechnologies within agricultural and horticultural settings, with the purpose of achieving enhanced production while maintaining ecological integrity. The growing global request for agricultural crops and products requires high standards of quality and safety, which has stimulated the search for new technologies that preserve their quality and delay their decomposition. Nanotechnology may boost plant production by improving nutrient uptake/use efficiency with nanoformulations of fertilizers and agrochemicals for plant enhancement, detection and treatment of diseases, and host-parasite interactions at the molecular level using nanosensors. It also may improve plant disease diagnostics, removal of contaminants from soil and water, postharvest management of vegetables and flowers, and reclamation of salt-affected soils. Although the markets for nanoproducts and nanoformulations continue to increase, there are also growing concerns regarding the fate and behavior of nanomaterials in environmental systems. Exploring important topics related to nanotechnology and nanomaterials, the book includes the use of nanochemicals in insect pest management, as nanofungicides, nanoherbicides, micronutrient supply, and nanosensors to monitor crop and soil health conditions, from detection of agrochemicals to their slow release of agrochemicals, and their impact on related environs. This book will serve as an excellent resource for a wide range of plant scientists who have concerns about nanomaterial interactions with terrestrial and aquatic plants.
This book addresses present-day landscapes, ecosystem functioning and biodiversity as legacies of the past. It implements an interdisciplinary approach to understand how natural or human-impacted ecological systems have changed over time. Historical Ecology combines theory, methods, regional case studies and syntheses to provide a complete up-to-date overview of historical ecology. Beginning with the crucial role of time and inference from observed patterns, the book critically reviews the main methodological approaches, including monitoring of permanent plots, analysis of old maps, repeat photography, remote sensing, soil analysis, charcoal analysis, botanical indicators, and combinations of these methods applied to forest ecosystems. A series of case studies from various biomes shows how historical ecology can help in understanding today's socio-ecosystems, such as mainland and island forests, orchards, tundra and coastal dunes. The book concludes by showing how historical ecology can answer timely fundamental research questions and provide science-based evidence for landscape and ecosystem management.
