Bury T21 soil bags. Bury whirl-paks in their corresponding plot. Measure or pace ~7m in a NE direction from the SW corner of each plot. At that point, place a meterstick perpendicular to the tape measure at the 50cm mark on the meterstick. Bury T21 A at one end and T21 B at the opposite end. In corn and poplar plots, the spacing should be adjusted to ensure both bags are buried within a row of wheat or poplars. Each bag gets buried over an orange garden marker at about a 45-degree angle with the top of the bag about 1” below the surface and the marker sticking out of the ground 1-2”. For removal in 21 days - someone can pull up on the orange marker to easily remove the bags. For burial, use a trowel or narrow shovel to lift the soil, place the marker and bag, and then remove the trowel and press down the soil to ensure contact with the buried bag. Try to disturb the plants as little as possible. A flag is placed at the 50cm point midway between the buried bags to help in locating them later. In T1-4 the flag should be in a corn row between the buried bags with all bags and flags within a row of corn. Wherever helpful, tie flagging tape on a plant above the flag, so it is easily located for collection.

The added REX radios caused the RF407 network to go into a nework storm. I turned off T7R4, R5, R3 and R1. The network traffic went back to normal. I restarted T7R1 and it's stable so far.
