Book Synopsis Working with Dynamic Crop Models by : Daniel Wallach
Download or read book Working with Dynamic Crop Models written by Daniel Wallach and published by Elsevier. This book was released on 2006-05-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models are being used more and more widely to study complex dynamic systems (global weather, ecological systems, hydrological systems, nuclear reactors etc. including the specific subject of this book, crop-soil systems). The models are important aids in understanding, predicting and managing these systems. Such models are complex and imperfect. One fundamental research direction is to seek a better understanding of how these systems function, and to propose mathematical expressions embodying that understanding. However, this is not sufficient. It is also essential to have tools (often mathematical and statistical methods) to aid in developing, improving and using the models built from those equations. The book is specifically concerned with the application of methods to crop models, but much of the material is also applicable to dynamic system models in other fields. The goal of this book is to fill that gap.* State-of-the-art methods explained simply and illustrated specifically for crop models* Parameter estimation – applying statistical methods to the complex case of crop models, including Bayesian methods * Includes model evaluation, understanding and estimating prediction error* Offers a unique data assimilation by using the Kalman filter and beyond

Book Synopsis Dynamic Modelling by : Alisson Brito
Download or read book Dynamic Modelling written by Alisson Brito and published by BoD – Books on Demand. This book was released on 2010-01-01 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: When talking about modelling it is natural to talk about simulation. Simulation is the imitation of the operation of a real-world process or systems over time. The objective is to generate a history of the model and the observation of that history helps us understand how the real-world system works, not necessarily involving the real-world into this process. A system (or process) model takes the form of a set of assumptions concerning its operation. In a model mathematical and logical assumptions are considered, and entities and their relationship are delimited. The objective of a model – and its respective simulation – is to answer a vast number of “what-if” questions. Some questions answered in this book are: What if the power distribution system does not work as expected? What if the produced ships were not able to transport all the demanded containers through the Yangtze River in China? And, what if an installed wind farm does not produce the expected amount of energyt? Answering these questions without a dynamic simulation model could be extremely expensive or even impossible in some cases and this book aims to present possible solutions to these problems.

Book Synopsis Soil and Crop Sensing for Precision Crop Production by : Minzan Li
Download or read book Soil and Crop Sensing for Precision Crop Production written by Minzan Li and published by Springer Nature. This book was released on 2022-09-07 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and crop sensing is a fundamental component and the first important step in precision agriculture. Unless the level of soil and crop variability is known, appropriate management decisions cannot be made and implemented. In the last few decades, various ground-based sensors have been developed to measure spatial variability in soil properties and nutrients, crop growth and yield, and pest conditions. Remote sensing as an important data collection tool has been increasingly used to map soil and crop growth variability as spatial, spectral and temporal resolutions of image data have improved significantly in recent years. While identifying spatial variability of soil and crop growth within fields is an important first step towards precision management, using that variability to formulate variable rate application plans of farming inputs such as fertilizers and pesticides is another essential step in precision agriculture.The purpose of this book is to present the historical, current and future developments of soil and crop sensing technologies with fundamentals and practical examples. The first chapter gives an overview of soil and crop sensing technologies for precision crop production. The next six chapters provide details on theories, methods, practical applications, as well as challenges and future research needs for all aspects of soil and crop sensing. The last two chapters show how soil and crop sensing technologies can be used for plant phenotyping and precision fertilization. The chapters are written by some of the world’s leading experts who have contributed significantly to the developments of precision agriculture technologies, especially in the area of soil and crop sensing. They use their knowledge, experiences, and successful stories to present informative and up-to-date information on relevant topics. Therefore, this book is an invaluable addition to the literature and can be used as a reference by scientists, engineers, practitioners, and college students for the dissemination and advancement of precision agriculture technologies for practical applications.
Book Synopsis Dynamic Efficiency and Productivity Measurement by : Elvira Silva
Download or read book Dynamic Efficiency and Productivity Measurement written by Elvira Silva and published by Oxford University Press, USA. This book was released on 2020 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The book takes on a systematic treatment of dynamic decision making and performance measurement. The analytical foundations of the dynamic production technology are introduced and developed in detail for several primal representations of the technology with an emphasis on dynamic directional distance functions. Dynamic cost minimization and dynamic profit maximization are developed for primal and dual representations of the dynamic technology. A dynamic production environment can be characterized as one where current production decisions impact future production possibilities. Consequently, the dynamic perspective of production relationships necessarily involves the close interplay between stock and flow elements in the transformation process, and how current decisions impact the changes in future stocks. Stock elements in the production transformation process can involve physical elements that can be effectively employed in the transformation process that can include the stock of technical knowledge and expertise available to the decision maker during the decision period. The dynamic generalization of concepts measuring the production structure (e.g., economies of scale, economies of scope, capacity utilization) and performance (e.g., allocative, scale and technical inefficiency, productivity) are developed from primal and dual perspectives"--

Book Synopsis A Systems Approach to Agroecology by : Pablo Tittonell
Download or read book A Systems Approach to Agroecology written by Pablo Tittonell and published by Springer Nature. This book was released on 2023-10-14 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: As agroecology gains momentum in the international research-for-development arena, there is an urgent need for methods and tools to support the codesign and evaluation of agroecological systems and their transitions. The social and ecological complexity of agroecosystems, their dynamics, uncertainties and sustainability, calls for a holistic, systemic approach to agroecology. As such, several questions arise for example: how do we deal with heterogeneity, landscapes, biodiversity or learning processes in agroecosystems analysis? How do we categorise diversity or analyse trade-offs in social-ecological interactions? How do we conceptualise, codesign and monitor agroecological transitions? This book sets out to answer these questions by building on the valuable ‘classics’ in agroecology. The book presents a systems perspective that underpins a combination of methodologies, ranging from participatory tools and field observations to mathematical simulation modelling. Researchers, advanced students and transdisciplinary practitioners will find in this book insights and methods to design research and (co-) innovation processes to foster agroecological transitions.

Book Synopsis Compensatory Growth: an Adaptation to Environmental Stress in Plants and Animals by : Chao Li
Download or read book Compensatory Growth: an Adaptation to Environmental Stress in Plants and Animals written by Chao Li and published by Frontiers Media SA. This book was released on 2024-03-27 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compensatory growth (CG) is defined as a change in growth rate (usually positive) following a period of reduced biomass or slowed growth due to some perturbation (e.g. nutrient deprivation, parasite load, tissue damage, or natural/anthropogenic disturbance). The phenomenon occurs throughout the plant and animal kingdoms, and while it is primarily observed in species with short lifespans, it has also been detected in longer-living organisms such as trees. CG occurs at the individual level as a variable life history trait but has the potential to impact the performance of whole populations and communities.
Book Synopsis Plant and Crop Modelling by : J. H. M. Thornley
Download or read book Plant and Crop Modelling written by J. H. M. Thornley and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a textbook (it includes, for example, exercises and outline solutions). The plant scientist is shown how to express physiological ideas mathematically and how to deduce quantitative conclusions, which can then be compared with experiment. There is little new biology in the book, but it is presented in a way that will be new to many biologists. The matching of models to experiments means using mathematics for formulating biological concepts and second, using algebra, calculus, or, now more frequently, computers to solve or simulate the resulting model; and finally, comparing, qualitatively or quantitatively, prediction to measurement. Computers are the important enabling technology that makes it all possible: solving equations, assembling models of increasing sophistication and complexity, and comparing theory with experiment. The book is divided into three parts. Part I. Covers subjects of wide relevance to modelling and plant biology. Part II. The reader may choose to select topics of particular interest from part II. However, the whole-plant modeller will need to study all chapters, and the plant ecosystem modeller may need to add other material also. Part III. Plant morphology is at an introductory level. It is included because morphological characters may prove to be of equal importance to some physiological traits in determining plant function and performance. "This textbook presents, in an interesting and clearly written fashion, a mathematical approach to a wide range of topics in plant and crop physiology, including light interception, leaf and canopy photosynthesis, respiration, partitioning, transpiration and water relations, branching and phyllotaxis. The biochemistry of plant growth and maintenanace is also presented in some detail. I was very pleased with the text, especially with the philosophy presented by the authors that biological models are necessarily simplifications of complex detail. I would strongly recommend it for reading and consultation by graduates and research workers." J. Exp. Botany "The authors' approach succeeds admirably, giving a thorough account of the mathematical toolbox available to researchers and the areas in which those tools have been used." Plant, Cell and Environment "Combining considerable technical cleverness with creativity and the refreshing notion that science is a "common-sense, unpredictable, fascinating and thoroughly human activity." Times Higher Educational Supplement "Exceptionally scholarly volume. Logical and systematic. Authors have assembled a mass of mathematical material in an elegant layout." Agricultural Systems
Book Synopsis High-Throughput Field Phenotyping to Advance Precision Agriculture and Enhance Genetic Gain, Volume II by : Andreas Hund
Download or read book High-Throughput Field Phenotyping to Advance Precision Agriculture and Enhance Genetic Gain, Volume II written by Andreas Hund and published by Frontiers Media SA. This book was released on 2024-03-01 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic is part of the High-Throughput Field Phenotyping to Advance Precision Agriculture and Enhance Genetic Gain series. The discipline of “High Throughput Field Phenotyping” (HTFP) has gained momentum in the last decade. HTFP includes a wide range of disciplines such as plant science, agronomy, remote sensing, and genetics; as well as biochemistry, imaging, computation, agricultural engineering, and robotics. High throughput technologies have substantially increased our ability to monitor and quantify field experiments and breeding nurseries at multiple scales. HTFP technology can not only rapidly and cost-effectively replace tedious and subjective ratings in the field, but can also unlock the potential of new, latent phenotypes representing underlying biological function. These advances have also provided the ability to follow crop growth and development across seasons at high and previously inaccessible spatial and temporal resolutions. By combining these data with measurements of all environmental factors affecting plant growth and yield (“Envirotyping”), genotypic-specific reaction norms and phenotypic plasticity may be elucidated.
