Discusses the latest information regarding the processes and mechanisms responsible for runoff and erosion by water in arable lands--detailing state-of-the-art water and soil conservation methods. Elucidates the rehabilitation of agricultural lands depleted by human activity.
This work provides the fundamental information necessary for the development of weed management strategies for all the major US crops using concepts that can be applied worldwide. Weed management systems are provided for cotton, peanut, soybean, wheat, barley, oat, sorghum, rice, fruits, nut crops, and more. The dynamics involved in creating the best management approaches for specific types of crops are explained.
Emphasizing the unpredictable nature of plant behaviour under stress and in relation to complex interactions of biological pathways, this work covers the versatility of plants in adapting to environmental change. It analyzes environmentally triggered adaptions in developmental programmes of plants that lead to permanent, heritable DNA modifications.
Learn the secrets of soil chemistry and its role in agriculture and the environment. Examine the fundamental laws of soil chemistry, how they affect dissolution, cation and anion exchange, and other reactions. Explore how water can form water-bridges and hydrogen bonding, the most common forces in adsorption, chelation, and more. Discover how electrical charges develop in soils creating electrochemical potentials forcing ions to move into the plant body through barriers such as root membranes, nourishing crops and plants. You can do all this and more with Principles of Soil Chemistry, Fourth Edition. Since the first edition published in 1982, this resource has made a name for itself as a tex...
This work provides information on the detection, identification, and differentiation of all microbial plant pathogens - presenting modern protocols for rapid diagnosis of diseases based on biological, physical, chemical and molecular properties. It contains methods for the selection of disease-free seeds and vegetatively propagated planting materials and quarantine techniques for screening newly introduced plant materials.
With contributions from experts in various specialties, Plant-Environment Interactions discusses recent advances in cellular and molecular regulation of stress tolerance. This third edition reviews new research in stress signal perception, cellular mechanisms, and genetic manipulation of stress tolerance for each individual stress. It addresses how to evaluate the level of plant tolerance to stress as well as how to link mechanisms identified through analysis of plant-environment interaction to producing stress-tolerant germplasm through biotechnology and traditional breeding. It also examines environmental stresses limiting plant productivity in agriculture, horticulture, and forestry.
A summary of data on heavy metal accumulation, biomonitoring, toxicity and tolerance, metal contamination and pollution in the environment, and the importance of biodiversity for environmental monitoring and cleanup of metal-contaminated and polluted ecosystems. It advocates the use of bacteria, mycorrhizae, freshwater algae, salt marshes, bryo- and pteridophytes, angiosperms, constructed wetlands, reed beds, and floating plant systems and tree crops to treat wastewaters and industrial effluents containing toxic heavy metals.
The need to understand the biological processes that are important for essential aquatic and terrestrial ecosystem function has prompted much research into the field of ecological enzymology. This book presents the two broad areas of application in a compilation of reviews by 21 international experts in their respective fields. The first explores enzymatic activities to assess the processes or mechanisms that operate in a given system, such as the rhizosphere, plant leaves and shoots, soil surfaces, and biofilms. The second considers enzymes or microbial cells as sensors to detect microbial activity and stresses due to pollution, management, or climatic change in both aquatic and terrestrial ecosystems.
Addressing a topic of major importance to the maintenance of world food supplies, this reference identifies knowledge gaps, defines priorities, and formulates recommendations for the improvement of the rice-wheat farming system. The book reveals new systems of rice intensification and management and illustrates the application of no-till and conser
"Offers the latest findings and research breakthroughs in plant ecology, as well as consideration of classic topics in environmental science and ecology. This wide-ranging compendium serves as an extremely accessible and useful resource for relative newcomers to the field as well as seasoned experts. Investigates plant structure and behavior across the ecological spectrum, from the leaf to the ecosystem levels."
