Regional pH in Five Agricultural Soil-Types – Associations with Temperature and Groundwater Si in Continental Finland

The role of weathering in carbon sequestration has not got attention enough. This study is assessing regional factors: annual temperature (Temp), groundwater (gw) Si, agricultural total (tot) and soil-type pHs and soil-type proportions (Prp) of moraine (mor), sand, silt, clay and mull soils in order to clarify whether weathering could be associated with pH variation in different soil-types. [mor + sand soils are labeled as coarse mineral soils (coms), respectively coms + silt + clays as mineral soils (miner). 1 -Prp.miner = Prp organic (org). Moraines, sands and clays include several subclasses].
