Abstract

Organic agriculture relies on organic fertilizers and amendments to provide nutrients to plants and will therefore depend on decomposer communities to release nutrients from these organic inputs. However, after conversion of conventional to organic agriculture it may take up to decades before decomposer communities become adapted to the new resource inputs. The aim of the present study is to investigate if the functional capacity of soil communities for decomposing recalcitrant crop residue types can be enhanced by inoculating soil communities from organically into conventionally managed soils. We used a microcosm incubation experiment to test how soil inoculation, agricultural management history, and crop residue type affect carbon and nitrogen cycling with crop residue addition. We collected soil samples from 5 pairs of conventional and nearby organic fields and set up a reciprocal inoculation experiment under controlled lab conditions. We inoculated soil from each conventional field with soil from the paired organic field and vice versa. To each soil mix, five types of crop residues were added: a cover crop mixture, carrot leaves (Daucus carota), alfalfa (Medicago sativa), hay (Lolium perenne), and straw (Triticum aestivum). There was one control treatment without any addition. Soils were incubated for 34 days and we measured mass loss of the crop residues from litter bags, cumulative soil respiration, cumulative potential plant available nutrients, permanganate oxidizable carbon (POXC), and substrate-induced respiration (SIR). Initial soil abiotic conditions (soil organic matter content, pH, C:N ratio, plant available nutrients), soil microbial biomass and soil bacterial and fungal community composition were also determined. We did not find clear effects of inoculation on mass loss and cumulative respiration. Instead, effects of crop residue type on all parameters were substantial. Crop residues with higher C:N ratios generally had lower mass loss and cumulative respiration, and resulted in lower nitrogen availability but higher POXC contents. Organic management enhanced cumulative respiration. There was little overlap in bacterial and fungal ASVs between the organic and conventional soils within each pair, resulting in a potential increase in diversity as a result of soil inoculation. We conclude that decomposition of crop residues declined with their recalcitrance, and that soils from organically managed fields did not increase the capacity of the soil community to decompose recalcitrant residues. Further studies are needed to determine whether compositional differences between soils from organic and conventional fields are a response to farming practices or whether management also has functional implications for soil fertility.

土壤接种对有机和常规管理农业土壤中作物残留物分解及碳氮循环的影响
有机农业依靠有机肥料和添加剂为植物提供养分,因此需要分解者群落从这些有机投入中释放养分。然而,从传统农业转变为有机农业后,分解者群落可能需要长达几十年的时间才能适应新的资源投入。本研究的目的是调查是否可以通过将有机土壤群落接种到常规管理土壤中来提高土壤群落分解难分解作物残留物类型的功能能力。我们利用微生态培养实验来检验土壤接种、农业管理历史和作物残留物类型如何影响作物残留物添加后的碳氮循环。我们从 5 对传统农田和附近的有机农田采集了土壤样本,并在受控实验室条件下进行了相互接种实验。我们将每块常规田的土壤与配对有机田的土壤进行接种,反之亦然。在每种混合土壤中都添加了五种作物残留物:覆盖作物混合物、胡萝卜叶(Daucus carota)、紫花苜蓿(Medicago sativa)、干草(Lolium perenne)和秸秆(Triticum aestivum)。还有一种对照处理没有添加任何物质。土壤培养 34 天后,我们测量了垃圾袋中作物残留物的质量损失、累积土壤呼吸作用、累积潜在植物可利用养分、高锰酸盐可氧化碳 (POXC) 和基质诱导呼吸作用 (SIR)。此外,还测定了初始土壤非生物条件(土壤有机质含量、pH 值、碳氮比、植物可利用养分)、土壤微生物生物量以及土壤细菌和真菌群落组成。我们没有发现接种对质量损失和累积呼吸的明显影响。相反,作物残茬类型对所有参数的影响都很大。一般来说,碳氮比较高的作物残留物的质量损失和累积呼吸量较低,氮可用性较低,但 POXC 含量较高。有机管理提高了累积呼吸作用。在每对土壤中,有机土壤和常规土壤的细菌和真菌 ASV 几乎没有重叠,因此土壤接种可能会增加多样性。我们得出的结论是,作物残留物的分解能力随着其难分解性而下降,有机管理田的土壤并没有提高土壤群落分解难分解残留物的能力。还需要进一步研究,以确定有机田和常规田土壤成分的差异是否是对耕作方式的反应,或者管理是否对土壤肥力也有功能性影响。
