Resumen
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) The control on the CO2 coming from soil handling, makes necessary the introduction of new methodologies that inform about the capacity of the soil as a carbon sink and about the carbon decay. It can be performed through the microbial growth yield efficiency concept by calorimetry and enthalpy balances. Here it is examined the sensitivity of these indicators to two metal layering phosphates, AZP [(NH)(4) Zn-2(PO)(4)(HPO)(4)] and AIP [(NH)(4) Fe(PO)(4) H2O] to assess about their soil impact. Both compounds caused metabolic changes on soil microbial biomass when compared to appropriated references indicating that the proposed methodology is sensitive to different inorganic sources of microbial growth. 93 2 657 665 Ministerio de Educacion y Ciencia in Spain Consejeria de Educacion y Ciencia in Asturias, Spain Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) FABESP in Brazil [MAT 2006-01997] [PC 06-020] Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) [MAT 2006-01997] [PC 06-020]
