Methods for determining the optimization of the humus content in arable soddy podzolic soils as exemplified by soils in the leningrad region russian sfsr ussr



Methods for determining the optimization of the humus content in arable soddy podzolic soils as exemplified by soils in the leningrad region russian sfsr ussr



Pochvovedenie (8): 21-28



Two types of methods are discussed: a method for characterizing and evaluating the content and composition of humus in the topsoil layer, and a method for creating and maintaining a quantity and composition which are optimal for a given region. To evaluate the type of topsoil layer with resepct to the content and composition of humus, it is necessary to determine the depth and density of the topsoil layer, content and reserve of humus, type of humic substances and nature of the humic regimen. To evaluate the humic regimen, the potential capacity for humus formation, intensity of humification and mineralization of the entire mass of organic matter, and the character of the transformation and intensity of mineralization of humic acids should be determined.
