The author has summarised results of the latest studies on the composition, structure and properties of humic substances, which are the largest and the most important component of organic matter of different types of soils. He has examined the group and fractional composition of…
World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the…
Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that so…
Presenting comprehensive, state-of-the-art information on plant growth regulators (PGRs), this unique reference details the various physiological responses in plants caused by microbially derived phytohormones - examining the microbial synthesis of the five primary classes of pl…
Assessment methods for soil carbon
by Lal, R.
fromAdvances in soil science (Boca Raton, Fla.)
"In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes in soil carbon. The book establishes the need for standardized methods, and helps us better understand the link between the pedosphere (soils) an…
"Soil in the Environment provides fundamental knowledge regarding the role of the soil as a central link in the chain of domains and processes comprising the terrestrial environment, a topic that must be an essential component of every curriculum in the environmental sciences. I…
