Late-summer soil water content on clear-cut reforestation areas two decades after site preparation in Finnish Lapland

摘要

Site preparation has been widely used on reforestation areas in Finnish Lapland due to the high soil moisture and low temperature. The long-term effect of site preparation on soil volumetric water content was studied in ploughed ridges and the untreated intermediate areas of prescribed burning, patch scarification, disk trenching and ploughing plots in eight reforestation experiments 19 years later. Soil water content (SWC) profile measurements were performed with a capacitance probe in the mineral topsoil in the dry late summer of 1993.
