This video demonstrates the technique for collecting a soil sample for hydraulic property analysis. The sampling area is cleared, and the top crust is evacuated. The sampling ring is then placed into the soil to collect the sample. The ring with the sample is then cleaned, labeled, packed, and transferred undisturbed for analysis.

Protocol

1. Sample collection

NOTE: A diagram of the research protocol workflow is represented in Figure 1. Proper sampling visualization is depicted in Figure 2.

1. Identify a representative area of ground to take the sample and clear plant material or other debris on the surface of the soil.
    NOTE: A representative area for the present study includes soil that was directly involved in crop management practices.
2. Excavate the top few centimeters above the desired sampling depth (approximately 5 cm below the surface soil) to remove un....
