从传统耕作到免耕土壤管理实践的转换通常与团聚体稳定性和无菌种群的改善有关。我们与英国农民一起测量了蚯蚓的面积（%）和与一般土壤相比与贝冢相关的蚯蚓数量。他们发现，贝冢覆盖了高达42%的土壤表面。中耕土壤（即，在贝冢下面的土壤）与比一般土壤（即，非中耕土壤），与科学现场试验的研究结果一致。我们在最近转换为免耕土壤管理实践的实验性田间试验中比较了中耕土壤与一般土壤的生物物理特性。我们测量了水稳定的聚集，土壤孔隙度在规模相关的水储存和气体扩散和无脊椎动物摄食活动。中间区域覆盖了13%的田间试验，并与显着改善团聚体的稳定性和孔隙度相比，一般土壤。我们的研究结果强调了在调查耕地系统的土壤质量和健康时考虑贝登的重要性。
The conversion from conventional tillage to no‐tillage soil management practices is generally associated with an improvement in aggregate stability and anecic earthworm populations. We worked with UK farmers who measuredLumbricus terrestrismidden area (%) and earthworm numbers associated with middens compared to the general soil. They found that middens covered up to 42% of the soil surface. Middened soil (i.e., soil underlying the middens) was associated with significantly more earthworms than the general soil (i.e., non‐middened soil) in agreement with research from scientific field trials. We compared the biophysical properties of middened soil to general soil across an experimental field trial recently converted to no‐tillage soil management practices. We measured water‐stable aggregation, soil porosity at scales relevant to water storage and gas diffusion and invertebrate feeding activity. Middened areas covered up to 13% of the field trial and were associated with significantly improved aggregate stability and porosity compared to the general soil. Our findings highlight the importance of considering middens when surveying soil quality and health in arable systems.
