Here are some photos from my veg team. They were taken today and show just some of the activities we perform during a vegetation sampling day.

Measuring crop height and diameter

The first image is of Saeid and myself measuring crop height and diameter and recording all of the info onto a field sheet. Each field has 3 pre-determined sampling points where all measurements are taken. Then vegetation is collected in labelled paper bags, and then sealed in plastic bags which we transport to the lab crew situated at Ma’s Drive-In in Elm Creek. Samples are then weighed (wet) and dried for about 2 days and weighed again (dry). The lab crew also separates the plant parts (leaves, stems) and weighs and dries those to determine where the bulk of the moisture is held within the plant.
