“…The application of plant biomass with a high carbon (C)/nitrogen (N) ratio (woodchip and grass straw), which could potentially compensate for soil losses based on recent C modeling (Dessureault-Rompré et al, 2020;Rodriguez et al, 2020) and restore physical properties Grégoire, 2020); and 2. The application of copper (Cu), based on Canadian recommendations (Mathur, 1987;OMAFRA, 2010) for peatlands with limited erosion because Cu has been reported to slow the degradation of organic matter by inhibiting extracellular enzymes (Floch et al, 2009;Mathur & Rayment, 1977;Mathur & Sanderson, 1978;Mathur & Sanderson, 1980;Wyszkowska et al, 2013).…”

Subsidence, erosion, and degradation in agricultural peatlands are leading to the disappearance of highly fertile farmland. This study investigated two strategies aimed at extending the lifespan of cultivated peat soils: the application of straw and wood chips to compensate for soil losses and the application of copper (Cu) to slow peat decomposition, based on previous recommendations. Peat soil samples (270 g) were amended with 11 t ha -1 of biomass materials (14.8 g kg -1 ) and 235.6 mg Cu kg -1 and incubated in glass jars at constant temperature and water content. Thirty chemical parameters were then monitored over a 56-d period through repeated soil sampling. Discriminant analysis showed that the addition of biomass had the greatest affect on nitrogen (N) availability, immobilizing 7.8 to 12.1 kg of inorganic N per metric ton of incorporated biomass. Considering that peat soils may require from 4 to 40 t biomass ha -1 yr -1 to reach carbon equilibrium, the tested biomass materials could immobilize from 34 to 500 kg ha -1 of N if confirmed at the field scale. This may help capture excess N but may also limit crop growth. Alternatively, slowing decomposition could reduce both biomass requirements and N immobilization. However, the results show that Cu had little effect on parameters linked to organic matter decomposition. Indeed, dissolved organic carbon was decreased by 11% in Cu-treated soils. A longer-term study should be conducted to confirm these observations at the field scale, thus helping to develop conservation strategies suitable for agricultural production.

“…The fiber content, on a volume basis, was determined by the method described by L6vesque and Dinel (1977). The steady state respiration was measured in samples with water added to give twothirds water-holding capacity, and incubated at 20'C in biometer flasks for 4 wk, as described by Mathur and Rayment (1977). Output of carbon dioxide was determined at half-weekly intervals.…”
