Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

Among the various derivatives of alkyl polyglucoside, the anionic alkyl polyglycoside esters (AGEs) and AGE-nonionic surfactant mixtures can able to increase wettability, and it may increase mineral content in soils. The phosphate alkyl polyglucosides show good performance in detergency and better wetting properties with good biodegradability. The sulfonated alkyl polyglucosides are a good alternative to nonylphenol ethoxylate and exhibit superior cleaning of edible oil.
