Book Description
After giving a brief history of tillage practices and implements used throughout the world dating back to ancient times, this book goes on to describe the basic soil mechanics techniques needed to calculate the forces developed in soil by simple-shaped cutting tools. The methods of measuring soil mechanical properties, water pressure in soil and shear rate effects are touched upon. A review is given of two and three dimensional soil cutting mathematical mechanics models to predict soil cutting forces and soil volumes disturbed by cutting and tillage tools, as well as the state-of-the-art of soil loosening, structural rearrangement and plant growth as affected by tillage tools. The author also includes an introduction to the analysis of traction machines. There are many numerical examples of mechanical analyses and predictions worked out in the various sections of the book as well as numerous unsolved problems at the end of a number of the chapters.Written in a textbook style, this monograph is ideal for anyone wanting to learn modern techniques for the mechanical description of soil cutting and tillage forces and soil volumes disturbed. It also provides a reference for analytical formulae and calculated force forces. It will be of interest to universities and colleges worldwide which have Agricultural Engineering Programs, Civil and Mechanical Engineering schools which specialize in soil mechanics and construction machinery as well as to research stations worldwide with interests in soil tillage, soil physics etc.

Book Description
The agricultural world has changed significantly during the last years. The excessive use of heavy machinery, waste disposal, the use of agrochemicals and new soil cultivation means led to severe problems, which agricultural engineers have to cope with in order to prevent soil from permanent irreversible damage. This Soil Biology volume will update readers on several cutting-edge aspects of sustainable soil engineering including topics such as: soil compaction, soil density increases, soil disturbance and soil fragmentation; soil tillage machineries and optimization of tillage tools; soil traffic and traction, effects of heavy agricultural machines, the use of robotics in agriculture and controlled traffic farming; mechanical weed control, the characterization of soil variability and the recycling of compost and biosolids in agricultural soils.

Book Description
Aiming to improve work efficiency in such areas as tillage in agriculture, earth-moving in civil engineering, and tunnel-making in sea-bed operations, this work offers an introduction to Finite Element Method (FEM) analysis of soil-machine systems. It explains the advantage of FEM's numerical approach over traditional analytical and empirical methods of dealing with complex factors from nonlinear mechanical behaviour to geometric configurations.

Book Description
This book gathers the latest advances, innovations, and applications in the field of innovative biosystems engineering for sustainable agriculture, forestry and food production. Focusing on the challenges of implementing sustainability in various contexts in the fields of biosystems engineering, it shows how the research has addressed the sustainable use of renewable and non-renewable resources. It also presents possible solutions to help achieve sustainable production. The Mid-Term Conference of the Italian Association of Agricultural Engineering (AIIA) is part of a series of conferences, seminars and meetings that the AIIA organizes, together with other public and private stakeholders, to promote the creation and dissemination of new knowledge in the sector. The contributions included in the book were selected by means of a rigorous peer-review process, and offer an extensive and multidisciplinary overview of interesting solutions in the field of innovative biosystems engineering for sustainable agriculture.

Book Description
Degradation of agricultural catchments due to water erosion is a major environmental threat at the global scale, with long-lasting destructive consequences valued at tens of billions of dollars per annum. Eroded soils lead to reduced crop yields and deprived agroecosystem’s functioning through, for example, decreased water holding capacity, poor aeration, scarce microbial activity, and loose soil structure. This can result in reduced carbon sequestration, limited nutrient cycling, contamination of water bodies due to eutrophication, low protection from floods and poor attention restoration—consequences that go far beyond the commonly modelled soil loss and deposition budgets. This book demonstrates, using data from the Harod catchment in northern Israel, how cutting-edge geoinformatics, data science methodologies and soil health indicators can be used to measure, predict, and regulate these major environmental hazards. It shows how these approaches are used to quantify—in time and space—the effect of water erosion not only on the soil layer, soil minerals, and soil loss, but also on the wide-range of services that agricultural ecosystems might supply for the benefit and well-being of humans. The algorithms described in this book play a major role in this paradigm shift and they include, for example, extraction of photogrammetric DEMs from drone's data, advanced drainage structure calculations, fuzzy process-based modelling and spatial topographic threshold computations, multicriteria analyses and expert-based systems development using analytic hierarchal processes, innovative data-mining and machine learning tools, autocorrelation and interpolation of soil health, physically-based soil evolution models, spatial decision support systems and many more.

Book Description
This book covers an array of issues on emerging agricultural engineering and technology, featuring new research and studies. The volume is broken into three parts: emerging technologies, energy management in agriculture, and management of natural resources, in which particular attention is paid to water management, a necessary consideration for successful crop production, especially in water-scarce regions. Topics include: alleviating drainage congestion solar energy for agriculture anaerobic digestion by inoculation with compost self-propelled inter-cultivators agrobiodiversity watershed development and management This volume offers academia, engineers, technologists, students, and others from different disciplines information to gain knowledge on the breadth and depth of this multifaceted field of agricultural engineering. There is an urgent need to explore and investigate the current shortcomings and challenges of the current innovations and challenges.
