Cone index penetrometer is a special apparatus widely used for assessing soil compaction in agriculture. 摘要圓錐指數儀是農業上用於測量土壤壓實度的專用設備。
They forked up as much of the soil possible,easing compaction. 他們儘可能的挖出泥土，減輕土壤夯實程度。
The residual porosity indicates the compaction state of the formations. 而剩餘孔隙度又反映了地層的壓實狀態。
Some turf areas stay saturated following rain while others dry out quickly, and other areas need more soak time to allow the water to penetrate through densely compacted soil. 一些草坪地區逗留飽和以下雨，而其他乾燥迅速，和其他領域需要更多的浸泡時間，讓水滲透，透過密集的壓實土壤。
