WebFinally, plant growth and land use change not only the amount of total organic matter in a soil but the way in which that organic matter is distributed with depth. Figure 3.2 shows, in a general way, the difference in organic carbon distribution between a soil developed under hardwood forest vegetation and under grass vegetation. WebSoil Moisture and Soil Temperature USCRN stations are equipped with three soil probes measuring temperature and moisture at 5, 10, 20, 50, and 100 cm depths (when possible). Each sensor records measurements at 5-minute intervals but only the observations at the 5-cm depth are saved to the datalogger.
