    This chapter reviews the methodologies used to present stable isotopically labeled substrates to microbial communities present in a wide range of environmental materials, and also discusses the wet chemical and instrumental methods used to determine compound-specific δ13C values of individual phospholipid fatty acid (PLFA). The different ways in which the δ 13C values Cited by: 5. AFE Principles and Practices of Agroforestry Systems 2+1.

    Phosphorus (P) is an essential nutrient for sustaining life and agricultural production. Transformation of readily available P into forms that are unavailable to plants adds costs to P replenishment, which eventually translates into lower agronomic benefits and potential loss of soil P into runoff may degrade water quality. Therefore, understanding the sources and pathways Cited by: 2.

These studies suggest that the following factors control the degree of isotope fractionation in non-traditional stable isotopes during various. An isotopic signature (also isotopic fingerprint) is a ratio of non-radiogenic 'stable isotopes', stable radiogenic isotopes, or unstable radioactive isotopes of particular elements in an investigated material.

The ratios of isotopes in a sample material are measured by isotope-ratio mass spectrometry against an isotopic reference process is called isotope analysis.
