For this test, undisturbed soil samples were used in the following conditions: natural moisture; air-dried (for at least 72 hours) and pre-moistened (by capillary rise, at least for 24 hours), being confined in cylindrical PVC rings, 5 cm high and 5 cm diameter.
Even under ideal conditions, simple capillary rise would draw in nectar much more slowly, only about 36 centimeters per second, the researchers report.
The experimental variables can be closely controlled in this technique and the capillary rise theory has been widely used in the literature with considerable exactitude.
The working version of the capillary rise equation is as follows:
where L is the capillary rise height, t is the time, [K.

Eq 7 shows the dependence of the index of maximum rate of capillary rise according to watering front on the selected drying parameters.
The field trial showed that to effectively control soluble salts, mulch amendments needed to improve both surface infiltration and subsurface permeability sufficient to mitigate against capillary rise during drying cycles.
Part G is the light source and part H is the digital video camera used to record the capillary rise observed in the capillary tube inside the optical cell.
Rolling presses the soil, it crushes the clods, it reduces the volume of non-capillaries and thus increases the capillary rise of water.
In this paper a modified technique based on capillary rise is used to measure the surface energy of several boron nitride powders.
