Última NO-LINEAR RESPIRATION DYNAMICS IN A DEGRADED ALFISOL AMENDED WITH DIFFERENT DOSE OF SALMON SLUDGES J. Soil Sci. Plant Nutr. Celis,J.E; Sandoval,M.A; Bello,N. No research has been conducted regarding respiration model parameters as a consequence of the application of salmon sludge on degraded Alfisols. In order to investigate kinetic parameters representing the decomposition of salmon sludge by means of respiration rates, sediment samples from a land-farmed pisciculture and a lake-salmon facility were applied to a degraded Alfisol at the Biobio region (Chile). Soil microbiological activity was evaluated on a 60-days laboratory incubation experiment under different salmon sludge addition dose: T1 25 t ha-1; T2: 50 t ha-1; T3: 75 t ha-1; T4: 100 t ha-1; T5: 150 t ha-1. A non-amended soil served as control. C0(2)-C production was determined in samples under closed incubation. A two-component first-order regression...

Bras. Ciênc. Solo Horák,Ingrid; Vidal-Torrado,Pablo; Silva,Alexandre Christófaro; Pessenda,Luiz Carlos Ruiz. The evolution of organic matter sources in soil is related to climate and vegetation dynamics in the past recorded in paleoenvironmental Quaternary deposits such as peatlands. For this reason, a Histosol of the mineralotrophic peatland from the Pau-de-Fruta Special Protection Area - SPA, Espinhaço Meridional, State of Minas Gerais, was described and characterized to evidence the soil constituent materials and properties as related to changes in environmental conditions, supported by the isotopic and elementary characterization of soil C and N and 14C ages. Samples were collected in a depression at 1,350 m asl, where Histosols are possibly more developed due to the great thickness (505 cm). Nowadays, the area is colonized by vegetation physiognomies of the...
