“…Willow chip incorporation at 40 and 60 Mg ha −1 in the previous fall reduced barley grain yield compared with the control due to soil N immobilization. Our results are in agreement with findings by Dessureault-Rompré et al (2022) who found a decreased lettuce (Lactuca sativa) yield by 35% and 14%, respectively, in soils amended with miscantus straw and willow chips. Li et al (2018) reported decrease in wheat growth and vigor with high concentrations of poplar chips.…”

“…The immobilization of soil mineral N following incorporation of willow chip corroborates previous findings (Holtz et al 2004;Gebhardt et al 2017;Espinosa et al 2020;Bourdon et al 2021;Dessureault-Rompré et al 2022;Marmier et al 2022). This N immobilization implies that willow chip addition can potentially mitigate nitrate availability for leaching, especially after potato harvest when high residual nitrate coexists with excessive moisture (Homyak et al 2008;Moorman et al 2010;Li et al 2013;Marmier et al 2022).…”

“…The impact of wood chips on soil N immobilization is inconsistent in the literature. Some studies observed N immobilization following wood chip applications (Mackensen et al 2003;Holtz et al 2004;Gebhardt et al 2017;Espinosa et al 2020;Bourdon et al 2021;Dessureault-Rompré et al 2022;Marmier et al 2022). Others found no N immobilization (Burgess et al 2002;Tahboub et al 2007).…”

“…Immobilization of inorganic N and possibly other nutrients (e.g., P) by soil microorganisms increases competition with plants for inorganic N and may result in N deficiency, stunted growth and reduced crop productivity. A number of studies have associated decreased crop growth and yield with N deficiency after wood chip incorporation into soils (N' Dayegamiye and Dubé 1986;Eldridge et al 2012;Li et al 2018;Dessureault-Rompré et al 2022). The magnitude and duration of wood chip effects on soil properties are related to the amount applied and decomposition rate.…”

Soil C, N and P bioavailability and cycling following amendment with shrub willow chips

Potato (Solanum tuberosum L.) crops are often cultivated in coarse-textured soils with low soil organic matter (SOM), and high nitrate leaching risk. Incorporating shrub willow chips into soil could enhance soil properties, while temporally immobilizing N and thus reducing N leaching. We performed a laboratory incubation study and a field experiment to evaluate the effects of shrub willow chips applied at increasing rates in the fall after the potato harvest on C, N and P cycling, soil pH and moisture, and on barley (Hordeum vulgare L.) yield in the following year. In comparison with the control, willow chip incorporation at the rates of 40 Mg ha-1 and 60 Mg ha-1 increased total C content, but it did not affect the activity of C cycling enzymes. Willow chip addition at these rates also induced nitrate immobilization and reduced barley grain yield and total N uptake, but increased the activity of N cycling enzymes (β-1,4-N-acetylglucosaminidase and leucine aminopeptidase). Mehlich-3 extractable P content and phosphomonoesterase activity were not affected by willow chip addition. Our results suggest that shrub willow chips increased total organic C and immobilized N following their incorporation and can thus mitigate nitrate leaching after the potato harvest. The N immobilization was short-lived and was not observed over second winter. We recommend to seed a forage legume in the spring following shrub willow chip incorporation. Willow chip incorporation is an effective means of increasing soil organic carbon.

Using cultivated organic soil depth to form soil conservation management zones

Cultivated Organic soils in Montreal's southwest plain are the most productive soils in the province of Quebec. After their initial drainage to enable farming, Organic soils are susceptible to many forms of degradation and soil loss. In this study, we characterized the physical, chemical, and pedological properties of 114 sites from five peatlands to form soil conservation management zones. We attempted to use the maximum peat thickness (MPT) as a soil degradation proxy. The MPT can be defined as the thickness of the layer of peat until coprogenous or mineral materials are reached. The latter are undesired growing media and are not considered in MPT calculation. A series of multivariate analysis of variance indicated that MPT was moderately related to soil degradation (optimal model's Pillai's trace = 0.495). Three soil degradation groups were defined, separated by two MPT thresholds: 60 and 100 cm. When looking at 17 different depth-property combinations, shallower sites (MPT < 60 cm) showed signs of soil degradation significantly higher than sites with an MPT above 60 cm. The second threshold was proposed for practical purposes. Then, these thresholds were used to separate the study area into spatially distinct management zones. Important spatial contrasts were found. This supports the theory that precision agriculture techniques are needed to target fields to optimize soil conservation interventions. The relationship between the MPT and soil degradation should be further explored to account for other degradation factors, and to better identify degraded soils and soils at risk.

Repeated applications of straw and wood chips were recently proposed as a conservation strategy for preserving cultivated peatland carbon (C) stock. However, the variability in the amendment biostability and the possible divergent responses of contrasting peat soils need to be assessed. This study investigated the effect of amendment with different plant materials on carbon dioxide (CO2) emissions from two contrasting peat soils (sapric and hemic) in two laboratory experiments. The sapric soil received one application of plant materials and was incubated for 3190 degree-days (145 days at 22°C), while the hemic soil received three successive applications of plant materials and was incubated for three successive periods of 3150 degree-days (126 days at 25°C). CO2 emissions were measured at time intervals ranging from 2 to 14 days and the apparent proportion of the plant material’s C remaining in the soil was modeled using an exponential decay function. CO2 emissions from the 0-25 cm horizon of the unamended peats represented 0.7 t C-CO2 ha-1 yr-1 in the sapric soil and 7.3, 1.1, and 0.5 t C-CO2 ha-1 yr-1 in the hemic soil for the first, second, and third amendment periods, respectively. The apparent remaining C of the plant material varied from 52% to 81% in the two experiments, resulting in biomass requirements ranging from 2 to 32 t ha-1. The apparent remaining C was from 26% to 36% higher in the sapric soil than in the hemic soil. The apparent remaining C was also 9% to 38% higher for the treated softwoods than the untreated materials (straws: miscanthus, switchgrass, sorghum; wood chips: willow, birch). The repeated application of straw and wood chips increased CO2 emissions in the first 35 days following each application, resulting in an increased decomposition rate for the tested model. However, no change was detected for the final apparent remaining C across the three applications. These findings highlight the importance of considering soil properties, material types, and the impact of repeated applications for designing effective amendment programs and accurate C projection models for cultivated peatlands.
