In November 2014, after the vegetation period ended in the Yellow River Delta, scientists of the IGSNRR and LREIS installed measurement equipment in the Yellow River Delta near the Yiqianer and Dawenliu nature reserve administration stations. An automatic measurement station was installed to monitor several soil parameters over the year. Water content, electric conductivity, temperature, in different soil layers, and groundwater depth, electric conductivity and temperature are measured every two hours and saved internally in the storage device.
Then the data are sent out twice every day to the server in IGSNRR. The measured soil parameters are important indicators for analyses of drought periods probably related to climate variation and anthropological impacts that threaten agricultural production and natural habitats in the Yellow River Delta region.
