Abstract:
... Compost is the most common organic fertilizer supplying nutrients and organic carbon to soil as well as improving soil physical, chemical and biochemical properties. On the contrary, biochar application to soil usually does not add nutrients, but can have effect on nutrient transformations and microbial community and alleviates soil acidity. Although these two products of organic residues recyclin ...

Abstract:
... The most accepted theories in soil ecology suggest that broad (e.g. respiration) and specialized (e.g. denitrification) functions are affected differently by resource availability and microbial communities in terrestrial ecosystems. However, there is a lack of experimental approaches quantifying and separating the role of microbial communities from the effect of soil abiotic properties on differen ...

Abstract:
... Soil quality is threatened by the increase in human population and by the fact that most of the cultivable land is intensively used. The initial interest in this topic focused on defining soil quality but shifted into how to measure soil quality in the late 1990s. There is a general agreement that soil biochemical, microbiological and biological properties are more suitable than physical and/or ch ...

Abstract:
... Composting has been recognised an alternative method to tannery sludge recycling and afterwards to be used in agriculture. As the tannery sludge contains salts and chromium, the application of composted tannery sludge (CTS) should be performed carefully to minimise negative effects on soil microbial properties. Therefore, this study evaluated the effects of 5-year repeated CTS amendment on soil mi ...

Abstract:
... Adding some pruning residues to the soil could result on phytotoxicity due to the presence of polyphenols. Pyrolysis of those residues could lead to a product with less polyphenols and a potential to be used as soil amendment. Soil biological properties, and, in particular soil enzyme activities have often been as indicators of soil quality. We tested phytotoxicity, using a germination test, and s ...
