This book describes latest analytical procedures of key soil health indicators including physical, chemical and biological parameters. Most of the Soil Analysis manuals currently available, primarily deal with basic chemical and physical properties without giving emphasis on soil health assessment. However, literature shows indicator parameters such as soil carbon pools, soil aggregation behaviour, aggregate associated carbon content and biological activity are increasingly being used for monitoring the change in soil quality / soil health over a period of time. Analytical protocols in respect of these parameters are presently available in different research journals. This book compiles the procedures for the soil health indicator parameters including those being used of late for monitoring soil quality/soil health. This book is useful for researchers, post graduate students, academicians and policy makers in the fields of Soil Science, Agronomy, Natural Resource Management and Forestry. Artikel-Nr. 131708
