Field capacity Water held by a soil after gravitational water has drained.
Hydraulic conductivity A measure of the ease with which water moves through a media such as soil or a membrane.

Soil texture Proportional distribution of soil particle sizes.
Symplastic path Path of water movement between symplast (cytoplasm) of adjacent cellsinside of cells and through plasmodesmata.
