Download or read book Microbial Strategies for Crop Improvement written by Mohammad Saghir Khan and published by Springer Science & Business Media. This book was released on 2009-08-25 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an ever-increasing human population, the demand placed upon the agriculture sector to supply more food is one of the greatest challenges for the agrarian community. In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.

Book excerpt: Pines are the most economically important group of trees in the world, covering large parts of the Northern Hemisphere and also being of silvicultural significance in many countries in the Southern Hemisphere. This book is compiled from 65 datasheets on pine from the Forestry Compendium Global Module (published by CABI on CD-ROM). For each species, there is information on common names, taxonomy, botanical features, natural distribution, latitude range, climate, soil properties, silvicultural characteristics, pests, wood and non-wood products.
Download or read book Phenology An Integrative Environmental Science written by Mark D. Schwartz and published by Springer Science & Business Media. This book was released on 2011-04-28 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenology is the study of plant and animal life cycle events, which are triggered by environmental changes, especially temperature. Wide ranges of phenomena are included, from first openings of leaf and flower buds, to insect hatchings and return of birds. Each one gives a ready measure of the environment as viewed by the associated organism. Thus, phenological events are ideal indicators of the impact of local and global changes in weather and climate on the earth's biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing and other areas. This book is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students and interested members of the public. With contributions from a diverse group of over fifty phenological experts, covering data collection, current research, methods and applications, it demonstrates the accomplishments and potential of phenology as an integrative environmental science.

Download or read book Autoecology and Ecophysiology of Woody Shrubs and Trees written by Ratikanta Maiti and published by John Wiley & Sons. This book was released on 2016-05-23 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest trees and shrubs play vital ecological roles, reducing the carbon load from the atmosphere by using carbon dioxide in photosynthesis and by the storage of carbon in biomass and wood as a source of energy. Autoecology deals with all aspects of woody plants; the dynamism of populations, physiological traits of trees, light requirements, life history patterns, and physiological and morphological characters. Ecophysiology is defined by various plant growth parameters such as leaf traits, xylem water potential, plant height, basal diameter, and crown architecture which are, in turn, influenced by physiological traits and environmental conditions in the forest ecosystem. In short, this book details research advances in various aspects of woody plants to help forest scientists and foresters manage and protect forest trees and plan their future research. Autoecology and Ecophysiology of Woody Shrubs and Trees is intended to be a guide for students of woody plant autoecology and ecophysiology, as well as for researchers in this field. It is also an invaluable resource for foresters to assist in effective management of forest resources.
Download or read book Remote Sensing of Drought written by and published by . This book was released on 2018-05 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Droughts and floods are water-related natural disasters which distress a broad range of ecological factors and activities related to agriculture, vegetation, human and wild life and local economies. Drought is the solo imperative weather-related natural disaster often aggravated by human action, since it distresses very large areas for months and years and thus has a thoughtful impact on regional food production, life expectancy for entire populations and economic performance of large regions or several countries. Traditional methods of drought assessment and monitoring rely on rainfall data, which are limited in the region, often inaccurate and, most importantly, difficult to obtain in near-real time. In contrast, the satellite-sensor data are consistently available and can be used to detect the onset of drought, its duration and magnitude. Even crop yields can be predicted 5 to 13 weeks prior to harvests using remote-sensing techniques. The need for proper quantification of drought impacts and monitoring and reporting of drought development is of critical importance in politically, economically and environmentally sensitive countries. Remote Sensing of Drought presents cutting-edge remote sensing tools and techniques that can be applied worldwide in order to the relevance of drought to natural hazards and climate change. To assess historical droughts and to provide drought monitoring, various indices have been proposed for different purposes and using different datasets. Despite the display of these indices, when one focuses on the processes that caused droughts, a set of consistent indices may adequately describe the different aspects of the droughts. Remote sensing techniques make it possible to obtain and distribute information rapidly over large areas by means of sensors operating in several spectral bands, mounted on aircraft or satellites. Several users such as top level policy makers at the national and international organizations, researchers, middle level policy makers at the state, province and local levels consultants, relief agencies and local producers including farmers, suppliers, traders and water managers are interested in reliable and accurate drought and flood information for effective management. This novel edition is packed with innovative remote sensing approaches to provide you with new perspectives on large-area drought monitoring and early warning.
