Chernozem is very fertile and can produce high agricultural yields with its high moisture storage capacity. The purpose of this research is to identify the moisture dynamic of Chernozem using high temporal resolution and accuracy data. We measured soil moisture every one hour for 2 years using TDR method in Bornuur soum, Tuv province Mongolia. During measurement period (2016, 2017), average soil volumetric water content was between 10.6 (% VWC) and 15.4 (% VWC). Snow melting has significant impact on soil moisture after mid-March and it becomes dry until rain. Rain which occurred in June, July and August is main source of soil moisture and soil keeps that moisture until October. Soil moisture was the highest in June and July of 2016 (23.3-27.8%) and August and September of 2017 (21.8-24.2%) which occurred lot of precipitations. In winter months (December to February) soil moisture was between 2.7% to 8.7%.
