Mitigation of peat extraction impacts by a new peat harvesting method protecting the peatland stored solid carbon

在加拿大，提取泥炭用于生产园艺基质是一个成熟的行业。然而，在这方面， 目前用于泥炭提取的方法耗尽了长期储存的碳（C）， 这一变化对在园艺和园艺中使用泥炭的社会可接受性产生了负面影响。 世界领先的泥炭生产和分销商Premier Tech Horticulture明白， 必须大大减少或停止。有了这个目标，总理科技园艺开创了一个新的 收获方法，命名为"顶片收获法"。因为新的泥炭切割方法 需要任何泥炭地排水，只收获泥炭的顶部地下（~10 cm）， 地表植被完好;我们假设长期储存的泥炭将保持完好（目标1）。此外，委员会认为， 最近的研究表明，这种收获方法可以通过减少泥炭分解来优化， 强化酶闭锁机制。目的二是检验酚类化合物对小鼠的抗衰老作用 添加物以减缓大规模田间试验中的分解。此外，这一潜力 将评估维持植物群和动物群生境的新收获方法（目标3），因为其目的是收获 泥炭生物量的循环，可持续和优化的方式。如果新的泥炭收获方法被证明是 成功地保护碳的长期储存不受泥炭地的影响，至少有三个非常积极的结果将 整个泥炭行业出现：1）碳排放量显着减少，缓解气候变化，2） 实现社会对泥炭使用的接受（消费者），以及3）创造新的就业机会和机会 在加拿大和全球销售专业收割设备。

Peat extraction for the production of horticultural substrates is a well-established industry in Canada. However, the current method used for peat extraction depletes the long-term stored carbon (C) contributing to climate change, having a negative impact on the social acceptability of using peat in gardening and horticulture. Premier Tech Horticulture, a world leader in peat production and distribution, understands that C emissions must be significantly reduced or halted. With that aim, Premier Tech Horticulture has pioneered a novel harvesting method, named the "acrotelm-harvesting method". Because the new peat cutting method does not require any draining of the peatlands and only harvests the top subsurface of the peat (~ 10 cm) leaving the surface vegetation intact; we suppose that the long-term stored peat will remain intact (objective 1). Moreover, recent research suggests that this harvesting method could be optimized by reducing peat decomposition by strengthening the mechanism of 'enzymic latch'. Objective 2 will test the effect of phenolic compound additions to slow down decomposition within a large-scale field experiment. Additionally, the potential of this new harvesting method to maintain flora and fauna habitats will be assessed (objective 3), as it aims to harvest peat biomass on a cyclical, sustainable, and optimized manner. If the new peat harvesting method proves to be successful in protecting the long-term storage of C from peatland, at least three very positive outcomes will emerge for the whole peat industry: 1) a significant reduction in C emissions mitigating climate change, 2) the achievement of social acceptability for peat use (consumers), and 3) the creation of new jobs and opportunities to sell specialized harvesting equipment in Canada and globally.
