Clays promote aggregation but can also be readily compacted. Follow the diagrams on these links to use the bulk density sampler. Bulk density is soil mass divided by unit volume.
Open the valve and fill the test hole, base plate, and funnel with sand. The soil removed, is carefully collected and weighed w. The container and soil weighed g when dried.
Performing a Sand Cone Measurement Once the sand and sand cone device have been calibrated using the procedure described in the previous section, sand cone measurements can be performed using the following procedure: 1 Fill the sand cone device with the same type of sand used for the calibration.
Big pores, macropores, facilitate free-water drainage, aeration, evaporation, and gas exchange. The shutter is opened, and the sand is filled in the cone and the hole. The base plate should not overhang the test hole, and the bottom of the test hole should be flat or concave upward.
The cylinder is removed and the sand formerly filling the cone is collected and weighed.
