We are conducting incubation experiments to measure N2O emission during thawing of froze soil. In November 11, Friday afternoon, we collected 5 intact soil cores (D 5cm * L 7cm) in warms season grass filter, woody buffer, cool season grass filter and crop field in Ron Risdal farm site, respectively (total 20 each). These soil cores are using for incubation experiments. Also simultaneously we collected a intact soil core (D 3.5cm * L 7 cm) beside the points where the intact soil cores (D 5cm X L 7cm) were collected (total 20 each). These soil cores are using for analyzing of soil properties such as soil moisture, bulk density, TN, TC, nitrate, ammonia, etc.
