Abstract

The conversion of bio-wastes to useful products such as biochar provide a suitable option not only to minimize the mass of wastes, but also to use the biochar as soil amendment. In the present study, food waste biochar (FWB) and agricultural waste derived biochar (AB), either alone or in combination (FWB + AB), were tested for their effects on soil microbiological characteristics (soil enzymes, soil basal as well as substrate-induced respiration), plant growth and photosynthetic parameters. Four treatments were tested: control, FWB, AB and FWB + AB. The results indicated that the application of AB significantly enhanced the plant above ground and below ground fresh and dry biomass as compared to other amendments and control (+41 to +205% compared to control). The application of FWB enhanced the quantum yield of photosystem II (QY-max, +4% compared to control) and normalized difference vegetation index (NDVI, +13% compared to control). Moreover, the FWB application improved the soil dehydrogenase (DHA) activity (+24% compared to control). Furthermore, the soil basal respiration was found to be increased under AB application (+46% compared to control) and the substrate-induced respirations were relatively decreased, depicting negative effects of applied biochars on substrate-induced respirations. Thus, we concluded that the differential responses of observed crop and soil attributes might be related to the biochar specific effects on soil properties.

  • Food waste-derived biochar holds great potential as a soil amendment due to its high nutrient content, which significantly improves soil chemical properties.

    “Food waste-derived biochar holds great potential as a soil amendment due to its high nutrient content, which significantly improves soil chemical properties [27, 28].”

    From Differential effects of sewage sludge and food waste biochars on <i>Miscanthus × giganteus</i> phytostabilization on acidic brownfield soil (2026) · cites this paper as [27]

    The Introduction describes biochar as a promising soil amendment, and Table 1 shows that the food waste-derived biochar had more nitrogen than the agricultural waste-derived biochar (3.58% versus 1.01%). The Discussion describes improvements in soil chemical properties from biochar generally, but our copy does not establish that the food waste-derived biochar significantly improved those properties because of its nutrient content. Section labels are available, but page numbers are not. (LLM, conf=0.85)

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.
