Environmental soil science is an upcoming field of science that has undergone rapid development over the past few decades. Most of the topics introduced in this book cover new techniques and applications of environmental soil science studies. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
