The drying of the upper soil layer in bare ground is progressing very fast, but that of the deeper layers is difficult. Furthermore, since the coefficient of water permeability of muddy soil after initial reclamation is as low as 10^<-5>-10^<-7>cm/sec and the greater part of soil water is absorbed on the soil particles, it is difficult to move soil water by means of gravity. Introduction of P. communis to polder may be an effective means of desiccating muddy soil, because active transpiration of P. communis plants can reduce soil water in the lower layers of the ground.P. communis can liberate a large amount of gas especially from the base of the culm into the surface water even under normal pressure in the afternoon in the summer season.

裸露地面上的上层土壤层的干燥非常快，但是较深的层的干燥很难。此外，由于初始回收后泥土的水通透性系数低至10^<-5> -10^<-7> cm/sec，并且大部分土壤水被吸收在土壤颗粒上，因此很难通过重力来移动土壤水。将P. communis引入冰原可能是使泥土干燥的有效手段，因为主动蒸腾植物可以减少地面下层的土壤水。公共可以将大量气体释放，尤其是在夏季的下午正常压力下，尤其是从Culm的底部从Culm的底部释放到地表水中。
