The main effects of Seaweed extracts (Ascophyllum, Fucus, Sargassum, Saccorhiza, Laminaria, Gelidium and others), when used as agricultural fertilizers, are better seed germination and higher quality fruit production, with longer shelf life; better use of soil nutrients; more productive crops and plants with greater resistance to unfavorable environmental conditions. Algae also have a long history of use as animal feed. They have a highly variable composition depending on the species, collection season and habitat, and on external conditions such as water temperature, light intensity and nutrient concentration in water. In relation to ruminal fermentation, a high variability of the digestibility values was found among seaweed species and cannot be attributed only to the composition of different nutrients of the algae. The role of marine algae for reduction of methane production is discussed with particular emphasis on novel algae-based feed strategies that target minimal methane emissions without affecting the functionality of the microbiota and overall animal productivity.

Through a long history of co-evolution, multicellular organisms form a complex of host cells plus many associated microorganism species. Consisting of algae, bacteria, archaea, fungi, protists and viruses, and collectively referred to as the microbiome, these microorganisms contribute to a range of important functions in their hosts, from nutrition, to behaviour and disease susceptibility. In this book, a diverse and international group of active researchers outline how multicellular organisms have become reliant on their microbiomes to function, and explore this vital interdependence across the breadth of soil, plant, animal and human hosts. They draw parallels and contrasts across hosts in different environments, and discuss how this invisible microbial ecosystem influences everything from the food we eat, to our health, to the correct functioning of ecosystems we depend on. This insightful read also pertinently encourages students and researchers in microbial ecology, ecology, and microbiology to consider how this interdependence may be key to mitigating environmental changes and developing microbial biotechnology to improve life on Earth.

Handbook of Slope Stabilisation (Paperback, Softcover reprint of hardcover 1st ed. 2004): J.A.R. Ortigao, Alberto Sayao Handbook of Slope Stabilisation (Paperback, Softcover reprint of hardcover 1st ed. 2004)
J.A.R. Ortigao, Alberto Sayao
R5,342 Discovery Miles 53 420 Ships in 7 - 11 working days

This book is aimed at the practising engineer and engineering geologist working in tropical environments, where lands lides are mainly triggered by rain fall. This book is based on a similar work published in 1999 in Portuguese, which became the Rio de Janeiro Slope Manual. This book is an engineering guide for the design of slopes and stabilisation works in rocks and residual soils. It evolves from the cumulative experience gathered by several engineers and geologists who faced severe slope problems. The authors' experience throughout Central and South America (Costa Rica, Argentina, Bolivia, Peru, Ecuador and Venezuela) and the Far East, especially Hong Kong and Malaysia, was used as a foundation for writing this book. The work also benefits enormously from the time spent in Hong Kong in 1996 and 1997 by the first editor on sabbatical at the City University of Hong Kong, and the discussions he had with many colleagues from the Geotechnical Engineering Office (GEO) of the Hong Kong Government, especially Dr. A. Malone, Mr. w.K. Pun, Dr. A. Li, Mr. K. Ho, and Mr. y.c. Chan among others.

Assessment Methods for Soil Carbon (Hardcover): John M. Kimble, Ronald F. Follett, B.A. Stewart Assessment Methods for Soil Carbon (Hardcover)
John M. Kimble, Ronald F. Follett, B.A. Stewart
R3,892 Discovery Miles 38 920 Ships in 12 - 17 working days

Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling
and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues.

In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.

The Origin of Mountains (Hardcover): Cliff Ollier, Colin Pain The Origin of Mountains (Hardcover)
Cliff Ollier, Colin Pain
R4,597 Discovery Miles 45 970 Ships in 12 - 17 working days

This volume describes mountains from all over the world, with an emphasis on mountain landforms, but also looks at their rocks, structure and age. This leads to a deduction on the mechanism which formed them, causing the authors to reject the pre-conceived and well known hypothesis that plate tectonics and folding creates mountains. The book approaches mountains from facts about mountain landscapes rather than theory. It illustrates that almost everywhere, mountains arose by vertical uplift of a former plain, and by a mixture of cracking and warping by earth movements, and erosion by rivers and glaciers, the present mountainous landscapes were created. It also gives evidence that this uplift only occured in the last few million years, a time scale which does not fit the plate tectonics theory. Another part of the evidence, shows that mountain uplift correlates very well with climatic change. Mountain building could have been responsible for the onset of the ice age. It certainly resulted in the creation of new environments.

Science and Technology of Organic Farming (Paperback, 2nd New edition): Allen V. Barker Science and Technology of Organic Farming (Paperback, 2nd New edition)
Allen V. Barker
R1,129 Discovery Miles 11 290 Ships in 10 - 20 working days

Organic farming is not only a philosophy; it is also a well-researched science. The second edition of The Science and Technology of Organic Farming presents the scientific basis of organic farming and the methods of application needed to achieve adequate yields through plant nutrition and protection. Organic farming is a scientifically derived method of improving soil fertility to increase agricultural yields with limited chemical inputs. As such, it can meet public demand for reduced chemical inputs in agriculture and play a key role in meeting the needs of a growing world population. The new edition of this highly regarded book gives clear and comprehensive details on how soil fertility can be maintained and how plants can be nourished in organic agriculture. Chapters on soil fertility and plant nutrition explain the chemistry of the plant, the soil, and the soil solution and outline the importance of plant macronutrients and micronutrients. The book offers practical information on using of green manures, composts and lime to maintain soil fertility; introduces methods of tillage of land; provides organic methods of controlling weeds, insects, and diseases; and suggests how food produce can be stored without refrigeration. The text provides information on how to assess and govern the nutritional status of crops and the fertility and condition of soil and presents guidelines, recommendations, and procedures for determining the best fertility recommendations for individual situations. This edition includes an entirely new chapter on hydroponics that explains organic approaches to hydroponic crop production. With a full bibliography of references, this text is a practical guide for anyone interested in organic farming, from farmers and agricultural advisers to teachers, soil scientists, plant scientist, entomologists and students of other biological and environmental sciences.

Global Climate Change and Cold Regions Ecosystems (Hardcover): John M. Kimble Global Climate Change and Cold Regions Ecosystems (Hardcover)
John M. Kimble
R3,847 Discovery Miles 38 470 Ships in 12 - 17 working days

Global Climate Change and Cold Regions Ecosystems provides information on soil processes and the carbon cycle in cold ecoregions as well as the soil carbon pool and its fluxes in the soils of cold ecoregions. Filling a void in this area of soil science, this resource explains soil processes influencing C dynamics under natural and disturbed ecosystems. The soils of the cold region ecosystems serve as a net sink of atmospheric C. However, an increase in global temperature could render them a net source. In the event of global warming, the cold regions ecosystems-arctic, sub-arctic, alpine, Antarctic, boreal forests, and peatlands-will undergo radical changes. Potential environmental change could drastically increase the active soil layer and influence the large C pool found in them. Topics include: soil C pools in different cold ecoregions, the impact of natural and anthropogenic disturbances on the soil C pool, the method of assessment of C and other properties of soils of the cold regions ecosytems while focusing on the fate of C in permafrost soils. Global Climate Change and Cold Regions Ecosystems covers the current and possible future effects of the cold ecoregions soil C pool on the global carbon pool.

Fraser Goff
R427 R366 Discovery Miles 3 660 Save R61 (14%) Ships in 7 - 11 working days

The Valles Caldera consists of a twelve-mile-wide collapsed volcanic crater and more than ten postcollapse volcanic domes in New Mexico's Jemez Mountains. For over a century, it was safeguarded within the 89,000-acre Baca Ranch. In the year 2000, Congress passed the Valles Caldera Preservation Act, creating the Valles Caldera Trust to purchase the ranch and create a nine-member board of trustees responsible for the protection and development of the Valles Caldera National Preserve.
With special permission, qualified geologists interested in volcanic processes and hydrothermal systems have been allowed to conduct research on the preserve. One of those volcanologists, Fraser Goff, collaborated with the Valles Caldera Trust to provide an accessible scientific overview of the caldera's geologic wonders.
Presented in two parts, Valles Caldera first offers a summary of significant geologic events that have taken place in the Valles Caldera area. Then Goff presents the geology, volcanology, and geothermal characteristics of the Caldera and the Jemez volcanic field. Geologic terms and names unfamiliar to all but professional geologists are defined in a summarizing glossary.

Ira D. Sasowsky, Carol M. Wicks
R2,835 Discovery Miles 28 350 Ships in 12 - 17 working days

Carbonate aquifers are an important source of water throughout the world. They are complicated systems and not always easy to interpret. Caves and channels form in the rock, leading to complex flow pathways and unpredictable contaminant behaviour. This volume covers the range of techniques used to analyse groundwater flow and contaminant transport in carbonate aquifers. The book opens with a review of thoughts and methods, and continues by discussing the use of tracers, hydrograph and hydrochemograph evaluation, estimation of aquifer properties from outcrop studies, numerical simulation, analogue simulation, and 3-D visualization of conduits. Other papers address the critical evaluation of matrix, fracture and conduit components of flow and storage. An understanding of these approaches is important to engineers or hydrogeologists working in carbonate aquifers.
