Microbial Biomass Carbon

Microbes and macrophytes often compete for available nutrients. In a nutrient-limited wetland, nutrients may be held tightly within the microbial biomass, reflecting efficient recycling of remineralized organic compounds. Environmental perturbations such as alterations in redox conditions may result in microbial mortality, resulting in a significant remineralization of nutrients. [Pg.116]

Soil microbial biomass constitutes a significant carbon sink, in that it represents a significant portion of the active organic carbon pool. Turnover of active biomass is generally on the order of days, as compared to several years for the soil organic matter. Nutrients may be held tightly [Pg.116]

The present text book is a comprehensive analytical manual covering the aspects of soil analysis in the major areas of Soil Physics and Soil Chemistry. Furthermore, the concept of soil microbial biomass carbon and nitrogen is also dealt in detail. An important feature of this text is that it describes not only the analytical procedures in detail but also furnishes sufficient theoretical background on the subject matter. The fundamental principles of the analytical methods have been discussed precisely and the theories explained well with mathematical analysis and chemical reactions whenever required. [Pg.182]
