Land application of organic waste products (OWPs), catch crops and reduced soil tillage are accepted as sustainable management practices in agriculture. They can optimize resources by supplying nutrients to plants and helping to maintain soil fertility. They also can influence soil functions in agricultural production systems. Soil microorganisms can feed on fresh organic matter by producing extracellular enzymes. Enzyme production responds to resource availability and soil C:N:P ratios, which could limit biogeochemical cycling. Allocating resources to produce nutrient-acquiring enzymes requires a large amount of energy to achieve optimal growth. In this context, studying the use of OWPs is important, as alternatives to long-term use of mineral fertilizers, to understand the dynamics of response and how the OWPs influence production of extracellular enzymes in the soil. Effects of OWPs on soil enzymatic activities have been studied widely, but long-term effects remain poorly understood, and no information is available about differences in dynamics among systems for each biogeochemical cycle. The data described here were collected during two trials from an initial state, and they allow assessment of long-term effects of OWP application, mineral nitrogen fertilization, tillage and vegetation cover on soil enzymatic activities. Data are presented for the activities of five soil enzymes measured from 2012 to 2019: β-glucosidase, phosphatase, urease, arylamidase and arylsulfatase. Five additional enzymes were included in 2019 to supplement the analysis of biogeochemical cycles: alkaline phosphatase, phosphodiesterase, α-glucosidase, β-galactosidase and n-acetyl-glucosaminidase. These activities were measured in two trials at the EFELE study site: PROs (five OWPs applied to a corn-wheat rotation) and TS/MO (four treatments that examine interactions between OWP and type of tillage). These data can be used as a reference for future studies of soil enzymes in France and other regions (e.g. for developing reduced-tillage systems and organic or inorganic amendments, and to assess dynamics of the systems).
有机废弃物（OWPs）的土地施用、填闲作物和减少土壤耕作被认为是农业可持续管理措施。它们可以通过为植物提供养分并有助于维持土壤肥力来优化资源。它们还会影响农业生产系统中的土壤功能。土壤微生物可以通过产生胞外酶来分解新鲜有机物。酶的产生对资源可用性和土壤碳氮磷比有响应，而这可能会限制生物地球化学循环。分配资源来产生获取养分的酶需要大量能量以实现最佳生长。在这种背景下，研究OWPs的使用很重要，作为长期使用矿物肥料的替代方法，以了解响应动态以及OWPs如何影响土壤中胞外酶的产生。OWPs对土壤酶活性的影响已得到广泛研究，但长期影响仍知之甚少，并且关于每个生物地球化学循环系统之间动态差异的信息尚无可用。此处描述的数据是在两项试验中从初始状态开始收集的，它们可以评估OWP施用、矿物氮肥、耕作和植被覆盖对土壤酶活性的长期影响。给出了2012年至2019年测量的五种土壤酶的活性数据：β-葡萄糖苷酶、磷酸酶、脲酶、芳基酰胺酶和芳基硫酸酯酶。2019年又纳入了另外五种酶以补充生物地球化学循环分析：碱性磷酸酶、磷酸二酯酶、α-葡萄糖苷酶、β-半乳糖苷酶和N-乙酰葡糖胺酶。这些活性在EFELE研究地点的两项试验中进行了测量：PROs（将五种OWPs应用于玉米-小麦轮作）和TS/MO（四种处理，研究OWP与耕作类型之间的相互作用）。这些数据可作为法国和其他地区未来土壤酶研究的参考（例如用于开发少耕系统以及有机或无机改良剂，并评估系统动态）。
