Effect of poultry litter biochar on soil enzymatic activity, ecotoxicity and plant growth
Abstract
Diversity of technological conditions and of raw materials from which biochar is produced is the reason why its soil application may have a varied effect on chemical and biological properties of soil and soil ecotoxicity. The aim of this study was to evaluate the effect of the addition of poultry litter (5.00tDMha−1) and biochar obtained from this material in doses of 2.25t and 5tDMha−1 on soil enzymatic activity, soil ecotoxicity and grass crop yield (pasture grass mix). The research was carried out under field conditions. No significant effect of biochar amendment on soil enzymatic activity was observed. The biochar-amended soil was low-toxic to Vibrio fischeri and non-toxic to Heterocypris incongruens. Application of poultry litter biochar in doses of 2.25t and 5tDMha−1 contributed to an increase in plant biomass production by 32% and 30%, respectively compared to the control (C). Biochar had more adverse effect on soil enzymatic activity and grass crop yield than non-converted poultry litter, but it significantly reduced soil toxicity to H. incongruens and V. fischeri.

The addition of biochar to soil reduced soil acidity and increased the content of nitrogen and organic carbon.
“Moreover, Mierzwa-Hersztek et al. (2016) reported that the addition of biochar to soil reduced soil acidity and increased the content of nitrogen and organic carbon.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
