Municipal solid waste compost application improves the negative impact of saline soil in two forage species
Abstract
Inappropriate utilization of biosolids may adversely impact agrosystem productivity. This article addresses the response of H. vulgare and P. monspeliensis to different doses (0, 100, and 150 t ha−1) of municipal solid waste (MSW) compost in a greenhouse pot experiment. Plant growth, heavy-metal uptake, gas exchange, and photosynthetic pigment concentrations and photosynthesis parameters were considered. Results showed that compost supply significantly increased shoot and root dry weights of both species, and this was positively correlated with nutrient uptake. Chlorophyll and carotenoid contents were positively influenced, especially in H. vulgare at rate of 100 t ha−1. Furthermore, MSW compost application increased net photosynthetic rate (A), stomatal conductance (Gs), and water-use efficiency (WUE) in both species. Alternatively, MSW compost amendment increased plant heavy-metal contents but levels remained lower than phytotoxic thresholds. This preliminary study suggests that a MSW supply at moderate doses (100 t ha−1) could be highly beneficial for plant productivity on saline soils.

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.
