(13 Jul) sky, partly sunny; wind, 5-10mph; air temp, 71.2°F; soil moisture, 20.0%; soil surface temp, 78.6°F; at 1-inch depth, 72.5°F; at 2-inch depth, 70.0°F; pH, 6.8. (10 Aug) sky, hazy sun; wind, 5-10mph; air temp, 89.4°F; soil moisture, 16.6%; soil surface temp, 90.0°F; at 1-inch depth, 82.9°F; at 2-inch depth, 81.0°F; pH, 6.3.
