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

Feeding Asia in the 21st century will require a second Green Revolution. However, unlike in the first generation, future yield increases will have to be grown using less water and nitrogen in a world of unfavorable climate change - this can only be done by increasing the efficiency of the photosynthetic system, i.e. developing a C4 rice plant. If and when achieved, it would be the first nonevolutionary example of reconstructing the primary metabolism of a plant. The impact of such a scientific achievement would be undeniable, but it requires either a superb feat of genetic engineering or forc

Agro-Ecosystem Diversity: Impact on Food Security and Environmental Quality presents cutting-edge exploration of developing novel farming systems and introduces landscape ecology to agronomy. It encompasses the broad range of links between agricultural development and ecological impact and how to limit the potential negative results. Presented in seven sections, each focusing on a specific challenge to sustaining diversity, the book provides insights toward the argument that by re-introducing diversity, it should be possible to maintain a high level of productivity of agro-ecosystems while also maintaining and/or restoring a satisfactory level of environment quality and biodiversity.

This second edition of Working with Dynamic Crop Models is meant for self-learning by researchers or for use in graduate level courses devoted to methods for working with dynamic models in crop, agricultural, and related sciences. Each chapter focuses on a particular topic and includes an introduction, a detailed explanation of the available methods, applications of the methods to one or two simple models that are followed throughout the book, real-life examples of the methods from literature, and finally a section detailing implementation of the methods using the R programmi

The future of agriculture greatly depends on our ability to enhance productivity without sacrificing long-term production potential. The application of microorganisms, such as the diverse bacterial species of plant growth promoting rhizobacteria (PGPR), represents an ecologically and economically sustainable strategy. The use of these bio-resources for the enhancement of crop productivity is gaining importance worldwide. Bacteria in Agrobiology: Crop Productivity focus on the role of beneficial bacteria in crop growth, increased nutrient uptake and mobilization, and defense against phytopathogens. Diverse group of agricultural crops and medicinal plants are described as well as PGPR-mediated bioremediation leading to food security.

This edited book deals with latest comprehensive information on conventional and high throughput techniques and technologies that are recently used to study plant microbial interface for agricultural research and enhancing plant productivity. Plant microbiota are important for many plant growth promotion activity and agricultural productivity and are sustainable green technology for enhancing agricultural productivity under changing environment. The book covers recent information about the plant associated microbiota and their ecology. It discusses technologies to isolate and test microbiota inhabiting in different portion of plants. The book explores the conventional methods as well as the most recently recognized high throughput technologies which are important for productive agroecosystems to feed the growing global population. This book is of interest to teachers, researchers, microbiologist, plant and environmental scientist and those interested in environment stewardship around the world. Also the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, soil science, and environmental sciences and policy makers to be a useful to read.

Climate change is directly linked to the human activities, according to the Fourth Assessment Report of IPCC (2007). In last two decades of 20th Century, accelerated anthropogenic activities pushed up the atmospheric abundance of greenhouse gases, mainly CO2, CH4, and N2O, alarmingly which enhanced the radiative forcing of the Earth’s surface and thus perturbed its heat radiation balance. As a consequence, atmospheric characteristics, such as temperature, rainfall pattern, levels of CO2 and O3 have changed significantly, affecting the farm productivity. Although rising level of CO2 may have fertilizing effect on C3 crops, but concomitant rise in atmospheric temperature, O3 level and extreme weather conditions can not only nullify the fertilizing effect of CO2, but also drastically reduce the crop production, threatening food security to burgeoning world population. Agricultural crops are not only victim of climate variability and extreme whether conditions, but also serve as a potential source of CH4 and N2O. Therefore, in changed scenario, Kyoto Protocol (1997) has sought all signatory developed nations to cut down their emission levels as per their differential commitments to UNFCCC and developing nations to invest in less carbon emission projects to avert the process of global warming process. In this context, the present edition, which compiles latest findings of studies carried out by the scientists on climate change and crops around the world, serves as a ready reckoner to crop scientists, atmospheric scientists, ecologists, environmentalists, research scholars and post- graduate students to update their knowledge and understanding on this issue.
