The book "Synergistic Biochar Boosts Soil and Plants" by Vineet Yadav is an informative and comprehensive guide on the benefits of using biochar in agriculture for boosting soil and plant health. Biochar is a form of charcoal that is produced from the pyrolysis of organic waste material, such as distilled waste, and is used as a soil amendment. The book explains how the synergistic effect of using biochar in combination with other organic materials can significantly improve soil fertility, MAPs productivity, and crop yields. The book discusses the numerous benefits of using biochar in agriculture, including its ability to increase carbon storage in soil, sequester carbon, and mitigate greenhouse gas emissions. Biochar also helps to improve soil quality by increasing nutrient retention, water holding capacity, and organic matter, as well as promoting microbial activity and enhancing plant growth. Moreover, the book highlights how using biochar in agriculture can contribute to sustainable development and environmental benefits. The book provides a comprehensive understanding of soil management, nutrient cycling, and soil remediation. It explains the biochemical properties of soil organic carbon and soil microorganisms, as well as the role of soil biology in sustainable agriculture. Additionally, the book covers the biochar production process, waste management, and soil respiration, acidity, and texture. Overall, "Synergistic Biochar Boosts Soil and Plants" is an excellent resource for anyone interested in learning about the benefits of using biochar in agriculture. It provides a comprehensive understanding of how biochar can be used as a sustainable agricultural practice, promoting soil health and crop productivity while contributing to climate change mitigation and environmental sustainability.

A foundation refers to the part of the structure that bears the load of the superstructure (structure above the plinth level) and also transfers the load from the structure to the ground/soil. Foundation engineering is a branch of civil engineering involved in the study and design of structures below the plinth level. It deals with the application of soil mechanics and rock mechanics in the design of foundation elements of structures. The design and construction of a foundation must have the power to sustain and transmit the dead and imposed loads to the soil. Foundations can be classified into four types including shallow foundations, deep foundations, monopile foundations, and individual footings. A foundation that is constructed where the hard strata are extremely near the ground surface rather than deep down the sub-layers of the ground, or the quality of the topsoil is sufficient for bearing is termed as shallow foundation. Continuous wall footings and pad or mat footings are common types of shallow foundations. This book provides comprehensive insights into the field of foundation engineering. It will serve a valuable source of reference for students interested in this branch of civil engineering.

Hydraulic conductivity of materials such as plants, soil and rocks is defined as the ability of the fluid to pass through pores, spaces or fractures. Saturated hydraulic conductivity is the ratio of volume flux to hydraulic gradient yielding a quantitative measure of a saturated soil's ability to transmit water when subjected to a hydraulic gradient. The level of hydraulic conductivity relies on many factors such as the intrinsic permeability of the material, the degree of saturation, and the density and viscosity of the fluid. There are two approaches that are used for the determination of hydraulic conductivity. In the first approach, the empirical approach, hydraulic conductivity is associated with soil properties such as pore size and particle size (grain size) distributions, and soil texture. In the second approach, the experimental approach, the hydraulic conductivity is determined from hydraulic experiments using Darcy's law. This book contains some path-breaking studies related to hydraulic conductivity. The topics included herein are of utmost significance and will provide incredible insights to the readers.

This book summarizes new discoveries on fracturing in chalk. Based on studies on the Danish North Sea, this book shows how observations from outcrop analogues, core and seismic data can be used to characterize the density, distribution and geometry of natural fractures in chalk and marl. Laboratory experiments on chalk samples reveal the controls on the geomechanical properties of chalk and thus on the growth of natural fractures. Finally, various modeling techniques are employed to investigate the mechanical deformation in the chalk structures of the Danish North Sea and to predict fracture distribution and geometry in the subsurface. An understanding of fracture density, distribution and geometry is essential for planning efficient fluid extraction or injection strategies and CO2 sequestration. This book provides the necessary knowledge.

The subject of thermo-hydro-mechanical coupled processes in fractured rock masses has close relevance to energy-related deep earth engineering activities, such as enhanced geothermal systems, geological disposal of radioactive waste, sequestration of CO2, long-term disposal of waste water and recovery of hydrocarbons from unconventional reservoirs. Despite great efforts by engineers and researchers, comprehensive understanding of the thermo-hydro-mechanical coupled processes in fractured rock mass remains a great challenge. The discrete element method (DEM), originally developed by Dr. Peter Cundall, has become widely used for the modeling of a rock mass, including its deformation, damage, fracturing and stability. DEM modeling of the coupled thermo-hydro-mechanical processes in fractured rock masses can provide some unique insights, to say the least, for better understanding of those complex issues.The authors of this book have participated in various projects involving DEM modeling of coupled thermo-hydro-mechanical processes during treatment of a rock mass by fluid injection and/or extraction and have provided consulting services to some of the largest oil-and-gas companies in the world. The breadth and depth of our engineering expertise are reflected by its successful applications in the major unconventional plays in the world, including Permian, Marcellus, Bakken, Eagle Ford, Horn River, Chicontepec, Sichuan, Ordos and many more. The unique combination of the state-of-the-art numerical modeling techniques with state-of-the-practice engineering applications makes the presented material relevant and valuable for engineering practice. We believe that it is beneficial to share the advances on this subject and promote some further development.
