• Abstract

  The experiment, started in 2005, aims at this stage to evaluate the C sequestration, changes in the amount of microbial C and their enzymatic activities (²-glucosidase, dehydrogenase, phosphatase and arylsulfatase), the quality of SOM and CO2 emissions due to the application of composted sewage sludge on recovered areas with natives species of Atlantic Forest. The treatments are: 10, 20, …

• Abstract

  The discarding of the produced sewer is a great problem in the world. An alternative is its recycling in the biosolid form, used as fertilizing and conditioning of the ground.For being rich in organic substance, it plays role of basic importance in the aggregate formation, in the capacity of kation exchange and water retention being, therefore, very important in the regeneration of degrad…
