WebSoil permeability is the property of the soil to transmit water and air and is one of the most important qualities to consider for fish culture. A pond built in impermeable soil will lose … WebA geologic unit that is highly permeable and can store and transmit a significant amount of groundwater is called an aquifer. When an aquifer is bounded by the water table on the top, the aquifer is called an unconfined aquifer. When an aquifer is confined between two much less permeable units, it is called a confined aquifer.

WebThe soils used in this experiment differed in potential nitrogen availability—from previous studies they were known to have different rates for nitrogen mobiliza- tion. The soils were combined with sand to give a porous mixture. The pots containing the soils were embedded in sand to stabilize the soil temperature (Plates 3 and 4).
