This book presents an overview of the fluvial processes theory developed in the former USSR at Lomonosov Moscow State University for the last 50 years, following the famous manuscript by Professor Makkaveev in 1955. Even being published solely in the Russian language, the theory and the author of the book, Prof. Roman Chalov, are well known in the World. This book consolidates for the first time in English, Chalov's work for the global audience. The book demonstrates how principles from fluvial geomorphology and hydrology are used to develop an ecosystem approach to river analysis and management. Despite a strong tradition in fluvial geomorphology work in the USSR, unfortunately, little has been made of insights provided on the international stage. The fluvial processes theory accepted in USSR was somewhat isolated during the long period of development from the English-language literature. The studied rivers are mostly located in Northern Eurasia and much different from those described in classical English-language works. Chalov allows the readers to interconnect two Worlds in Geomorphology, building bridges between the classical international geomorphology and the equally in-depth and thorough but isolated research in the USSR.
This book provides a comprehensive overview of the current knowledge on the fate and interaction of pharmaceuticals in soil-crop systems. It addresses the principles of their transport, uptake and metabolism and reviews methodologies for their analytical determination. It also discusses ecotoxicological effects arising from their presence and highlights bioremediation approaches for their removal. The use of treated wastewater to irrigate crops is becoming more widespread in regions where freshwater is limited. This practice conserves freshwater resources and contributes to nutrient recycling. However, concerns remain regarding the safety of irrigation with treated wastewater since it contains residues of pharmaceuticals that have survived treatment, which means that soil and fauna are potentially exposed to these xenobiotics. Various pathways govern the fate of pharmaceuticals in crop-soil systems, including soil degradation; formation of non-extractable residues; uptake by soil-dwelling organisms (e.g. earthworms); and uptake, transport, and metabolism in agricultural crops. Investigations into these aspects have only recently been initiated, and there is still a long way to go before a meaningful assessment of the impact of wastewater has been completed.
When stresses are applied to saturated soil, deformation will occur as water in voids is squeezed out. Consolidation Analyses of Soils focuses on the consolidation of fully saturated soils. The book follows a classic approach by beginning with one-dimensional constitutive relations of soils and one-dimensional consolidation. It then moves on to analytical solutions to several one-dimensional consolidation problems and one-dimensional finite strain consolidation. The authors also present a finite element method for consolidation analysis of one-dimensional problems, analytical solutions to consolidation of soil with vertical drains, and a finite difference method for consolidation analysis of one-dimensional problems. Simplified methods for consolidation analysis of soils exhibiting creep are introduced and applied to different cases. Three-dimensional consolidation equations and solutions of typical three-dimensional consolidation problems are covered, as well as simplified finite element consolidation analysis of soils with vertical drain and finite element method for three-dimensional consolidation problems. The book is unique in that it covers both classic solutions and state-of-the-art work in consolidation analyses of soils. Authors Jian-Hua Yin is Chair Professor of Soil Mechanics in the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University. Guofu Zhu is a Professor in the Department of Engineering Structures and Mechanics at Wuhan University of Technology, China.

The soil water retention curve, the saturated hydraulic conductivity and the unsaturated hydraulic conductivity function are basic soil hydraulic functions and parameters. Ample apprehension of the soil hydraulic functions and parameters is required for a successful formulation of the principles leading to sustainable soil management, agricultural production and environmental protection. From these, all the other parameters, required in the solution of the practical tasks, are derived. The basic soil hydraulic functions are strongly dependent upon the soil porous system. The development of models is characteristic by the gradual transition from the simplest concepts up to the sophisticated approaches, which should correspond to the visual reality studied by soil micromorphology. 2 Soil Porous System and Soil Micromorphometry 2.1 An Overview on the Quantification of the Soil Porous System Quanti? cation of the soil porous system consists of classi? cation of soil pores, ch- acterization of the soil pores shapes and the estimation of the pore size distribution function. When the hydraulic functions of the soil pores are considered, the following laws of hydrostatics and hydrodynamics are applied as best ? tting to the classi? cation criteria of the size of the pores (Kutilek and Nielsen 1994, p. 20, Kutilek 2004): A. Submicroscopic pores that are so small that they preclude clusters of water molecules from forming ? uid particles or continuous water ? ow paths.
The book gives a detailed description of the application of DSSAT in simulating crop and soil processes within various Agro-ecological zones in Africa. The book, an output of a series of 3 workshops, provides examples of the application of DSSAT models to simulate nitrogen applications, soil and water conservation practices including effects of zai technology, phosphorus and maize productivity, generation of genetic coefficients, long-term soil fertility management technologies in the drylands, microdosing, optimization of nitrogen x germplasms x water, spatial analysis of water and nutrient use efficiencies and, tradeoff analysis. The minimum dataset requirements for DSSAT is discussed. This book arises from attempts to address the limited use of models in decision support by African agricultural (both soil scientist and agronomists) scientists.
The search for new strategies of pest control with safer molecules is currently of great importance and interest. Microbe-mediated biological crop protection is an attractive and promising technology with no concern for a negative impact on the environment and biodiversity. Microbial hydrolytic enzymes such as proteases, chitinases, lipases, etc. are attractive for this purpose. They present toxic properties and act synergistically to control pest attacks. Also, some metabolites, that microorganisms produce for their survival or defense, can be explored and exploited for plant protection. The focus of this Volume is on the potential of microbial hydrolytic enzymes and their metabolites in agroecosystem functioning. Subsequent chapters review topics such as microbial hydrolytic enzymes as powerful management tools, chitinases in IPM of agro-horticultural crops, metabolites as pesticides and the importance of the metabolites of entomopathogenic fungi, metabolites and virulence factors. Other topicas include: microbial-based nanoparticles, recombinant DNA technologies to improve the efficacy of microbial insecticides, the effects of entomopathogens on insect predators and parasitoids, and the management of major vegetable insect pests. This Volume provides detailed accounts on the safe use of microbial products for sustainable management of insect pests. Its aim is to build solid foundations for the students, teachers, and researchers interested in eco-friendly management of important insect crop pests.
In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Despite its many origins in agronomic problems, statistics today is often unrecognizable in this context. Numerous recent methodological approaches and advances originated in other subject-matter areas and agronomists frequently find it difficult to see their immediate relation to questions that their disciplines raise. On the other hand, statisticians often fail to recognize the riches of challenging data analytical problems contemporary plant and soil science provides.
With the increasing concern over rural livelihoods and the food security of poor communities in developing countries, it is vital that land quality is maintained. Yet, land degradation is widespread and is lowering the productive capacity of the land in these countries. This practical handbook presents simple, non-technical indicators for assessing land degradation in the field. Based on the perspective of the farmer, the methods selected lend meaning to real farming situations, helping the field professional to understand not only the impact of degradation but also the benefits to be gained from reversing it. The handbook shows how to calculate indicators such as those of soil loss, explains the interpretation of results and in particular how combinations of different indicators can give conclusive evidence of the severity of land degradation. The focus of the book is firmly on understanding the farmer's interaction with the land, and how environmental protection, food security and the well-being of rural land users may be assured. With detailed figures, photographs, worked examples and sample forms based on assessment techniques validated by field professionals in Africa, Asia and Latin America, this will be an essential training manual will be invaluable for field-workers in NGOs and in governmental and educational institutions. It will also be of interest to researchers and academics in development, environment and agriculture.

An increasing population has put tremendous pressure on agricultural productivity to fulfill the demands of human consumption. Numerous agricultural activities and techniques have been developed to raise annual crop production globally. While agriculture has succeeded in enhancing the yearly crop productivity, this achievement is at the cost of environmental degradation by applying synthetic persistent substances, such as industrial fertilizers, pesticides, herbicides, etc. Chemical fertilizers are nearly as destructive as they are productive, causing monocultures and consequences associated with elimination of diversity, nutrient pollution as evidenced by algae blooms, eutrophication, water quality issues, lower oxygen levels and dangers to fish stocks. Therefore, the scientific approach to maintain sustainable fertility in soil and plants is to switch over to biofertilisers.Biofertilisers are compounds of organic matter that are applied to crops for growth and health. Their constituent micro-organisms interact in an ecofriendly manner with the soil, root and seeds of plants, promoting the growth of micro-flora that enhances soil fertility. They are known to play a number of vital roles in soil fertility, crop productivity and production in agriculture. Application of biofertilisers results in increased mineral and water uptake, root development, vegetative growth and nitrogen fixation. They liberate growth promoting substances and vitamins and help to maintain soil fertility. They act as antagonists and play a pivotal role in neutralising the soil borne plant pathogens, thereby assisting in the bio-control of diseases. Application of biofertilisers in lieu of synthetic fertilizers could be the promising technique to raise agricultural productivity without degrading the environmental quality. The present book focuses on the latest research approaches and updates from the microbiota ecosystem and their applications in agriculture industry. It also highlights the great potential and possible future of action of microbiota in the development of sustainable agricultural systems.

For more than 30 years, soil testing has been widely used as a basis for determining lime and fertilizer needs. Today, a number of procedures are used for determining everything from soil pH and lime requirement, to the level of extractable nutrient elements. And as the number of cropped fields being tested increases, more and more farmers and growers will come to rely on soil test results. But if soil testing is to be an effective means of evaluating the fertility status of soils, standardization of methodology is essential. No single test is appropriate for all soils.
In their rapid colonization of soil exposed by fires, floods, and grazing animals, weeds resemble the human specialists we label Emergency Medical Technicians (EMTs). Weeds are the first responders when disasters occur in nature. They occupy bare soil and prevent erosion by wind and water. In extreme cases such as a landslide, weeds are essential to the healing processes that replace the lost soil. Like a Band-Aid on a skinned knee, weeds protect the land while it recovers. Besides protecting the soil after disaster, weeds provide food for wildlife, and some of them provide food and medicine for people. Able to withstand harsh conditions, weeds will proliferate as global warming and other human impacts intensify. Thus, nature's EMTs will increase while all other plants decline. The book provides a succinct definition of weeds according to their form and function in ecosystem processes. The narrative uses a representative set of weed species from a desert location to illustrate the full range of weed characteristics.
This book discusses Nevada in the context of the history of soil investigations; soil-forming factors; general soil regions; soil geomorphology; taxonomic structure of the soils; taxonomic soil regions; soil-forming processes; benchmark, endemic, rare, and endangered soils; and use of soils. With an average mean annual precipitation of 175 mm (7 in), Nevada is the driest state in the USA. More than three-quarters (89%) of the state has been mapped and the first soil survey was completed in 1909. Nevada is divided into 10 major land-resource areas and features two large deserts (the Great Basin Desert and the Mojave Desert), and over 100 north-south trending enclosed basins separated by mountain ranges (Basin and Range Province), several of which have peaks exceeding 3,400 m. Further, the soils of Nevada represent seven of the 12 globally recognized orders, 29 suborders, 69 great groups, and over 1,800 soil series, and some of the classic research on the origin of duripans and petrocalcic horizons was conducted in the state. This book presents the first report on the soils of Nevada and provides the first soil map of Nevada utilizing soil.
