Interrelationships Between Microorganisms And Plants In Soil

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 These proceedings present the most up-to-date information on the interrelations between microorganisms and plants in the rhizosphere, and the possibility of utilizing these relationships to improve plant growth, health and yields. The application of some biological preparations may in the future partially replace the use of agrochemicals and thus contribute to environmental improvement and enhancement of the quality of soil, water and foodstuffs.The Symposium brought together specialists from fifteen countries to assess the advances in a field which has recently attracted considerable interest and is also important for society at large. The book contains over sixty contributions from rhizosphere microbiologists, focusing on the study of the function of microorganisms in the root system of crop plants and in its immediate vicinity, the effect of the plants themselves on this function, the interrelationships among different microorganisms in the rhizosphere and the elucidation of the mechanisms of microbial action in the agroecosystem. All these lines of research are intimately associated with the problems of soil fertility and crop yields, which in turn have a direct bearing on the nutrition of mankind and on environmental protection. The papers have been divided into four topics: symbiotic microorganisms in the root system; associative microorganisms in the root system; soil-borne phytopathogenic and phytotoxic microorganisms; and microbial preparations stimulating growth and improving the plant health. Each section starts with invited lectures from outstanding specialists. The work includes numerous tables, figures and references.The volume is primarily directed at soil microbiologists, plant pathologists and physiologists, ecologists as well as specialists in agronomy and environmental protection.

Chemistry Of Soil Organic Matter

de K. Kumada

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Despite the large number of papers and books published on soil organic matter (humus), our knowledge of the subject is still very limited, as is our knowledge of humic acid. The author of this book began to study humus at the end of the 1940s and continued until 1984 when he retired from Nagoya University. With the intention of establishing a systematic understanding of soil organic matter, he has compiled facts and a discussion of humus based on his extensive experimental results during the past 40 years.In this book, humic acids are classified into A, B, Rp and P types, based on their optical properties. The elementary composition and other chemical properties of humic acid types are shown to be regularly different from each other. A new method for humus composition analysis applied to various kinds of soils in Japan and several other countries indicates that the diversity of humus compositions of soils is systematically understandable. These findings lead the author to novel theories on the chemical configuration and formation of humic acids and humic substances. Diagenesis of humus under terrestrial conditions is illustrated as to the buried humic horizons of Black soil (Andosol).The book will be useful not only to soil scientists and agronomists but also to geochemists, oceanographers, limnologists, water scientists, biologists and chemists who are dealing with organic matter in terrestrial, aquatic, and sedimentary environments.

Soil Physics With Basic - Transport Models For Soil-Plant Systems

de G.S. Campbell

58,29€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book covers material taught in a graduate-level soil physics course at Washington State University. While most soil physics courses dwell mainly on deriving rather than solving the differential equations for transport, the author''s approach is to focus on solutions. Graduate students in agricultural and biological sciences usually have a good working knowledge of algebra and calculus, but not of differential equations. In order to teach methods for solving very difficult differential equations with difficult boundary conditions using fairly simple mathematical tools, the author uses numerical procedures on microcomputers to solve the differential equations. Numerical methods convert differential equations into algebraic equations which can be solved using conventional methods of linear algebra.This book reflects the philosophy used in the course. Each chapter introduces soil physics concepts, generally in the conventional way. Most chapters then go on to develop simple computer programs to solve the equations and illustrate the points made in the discussion. Problems at the end of each chapter help the reader practice using the concepts introduced in the chapter. The problems and computer programs are an integral part of the presentation, and readers are strongly encouraged to experiment with each model until both the working of the model and the concepts it teaches are familiar. Although the programs are generally short and relatively simple, they are suitable for use as submodels in large, general-purpose models of the soil-plant-atmosphere system, and have been used in this way by the author and by several of his students.Teachers and students alike will welcome this new textbook. It will enable graduate students to understand and solve transport problems which exist in field situations, and will provide them with a good working knowledge of soil physics - fundamental to so many other areas in soil, plant and engineering sciences.

 Developments in Soil Science, 5A: Soil Chemistry: A: Basic Elements focuses on the advancements in the processes, methodologies, principles, and approaches involved in soil chemistry. The selection first elaborates on the composition of the soil, chemical equilibria, and surface interaction between the soil solid phase and the soil solution. Topics include properties of the liquid layer adjacent to the solid phase, influence of the interaction between solid and liquid phase on soil properties, reactions involving the transfer of protons and/or electrons, calculation of equilibrium constants from thermodynamic data, solid phase components, and gas phase. The manuscript then takes a look at the adsorption of cations and anions by soil, common solubility equilibria in soils, and transport and accumulation of soluble soil components. Discussions focus on solute displacement in soil, transport with and in the liquid phase, iron oxides and hydroxides, carbonate equilibria, anion exclusion at negatively charged surfaces, and highly selective adsorption of cations by soil. The text ponders on the pollution of soil, saline and sodic soils, and chemical equilibria and soil formation, including weathering and soil minerals, reverse weathering, sodication of soils upon irrigation, chemical aspects of the reclamation of saline and sodic soils, and recognition and prediction of soil pollution. The selection is a valuable source of data for researchers wanting to study soil chemistry.

Fractals In Soil Science

258,38€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book presents the state-of-the-art after fifteen years of exponentially growing applications of fractal geometry in soil science. It demonstrates the wide-ranging applicability of fractal models in soil science and indicates new opportunities to integrate processes in soils within or across scales using fractals. Contributed by some of the pioneers in the field, chapters represent a broad spectrum of applications from geochemistry to microbiology and from scales of micrometers to the landscape, and serve as an introduction to the subject.Topics include fractal aspects of soil structure, porosity and texture, scaling in preferential and hydraulic conductivity, anoxic volumes and adsorption in fractal models of soil, characterization of the pore surface irregularity, fractal properties of soil organic matter, fractal concepts in studies of soil fauna and mycelium in soils, and fractal analysis of spatial and temporal variability in soil properties and crop yields. A wide spectrum of methods for identifying and measuring fractal properties is introduced and critically discussed. Although the book focussed on solving problems in soil science, the applications and the fractal approach used share much in common with many other fields within and outside of the earth sciences. A unique bibliography on fractals in soils science is included.
