种植杨柳杆提供的阻力，以连根拔起和强度的个人根在张力进行了测定。极点的稳定性在很大程度上取决于极点的年龄和间距，周围物质的粒度和/或分层，以及侵蚀的类型和严重程度。一个简单的模型的基础上的观察极故障估计的最大电阻，可以提供一个极，并用于链接现场结果和实验室测试。提出了改进种植技术的建议
The resistance offered by planted willow poles to uprooting and the strength of individual roots in tension were determined. Pole stability strongly depends upon pole age and spacing, the grain size and/or layering of the surrounding material, and on the type and severity of erosion. A simple model based on observations of pole failure is developed to estimate the maximum resistance that can be offered by a pole and used to link field results and laboratory tests. Some suggestions are made for improvements in planting techniques
