Summer Soil Temperatures On Algific Talus Slopes In Northeast Iowa, Tom R. Cottrell, Kyle S. Strode
Journal of the Iowa Academy of Science: JIAS
Soil temperatures at 15 cm depth were recorded on a single occasion at multiple grid points on two algific talus slopes during the summer of 1999. To represent and compare soil temperatures over a wider area, soil temperatures were measured (less intensively) at five other algific slopes and three non-algific forested slopes. Algific slopes appear to have greater variation in soil temperatures than non-algific sites. Spatial variation in algific slope soil temperatures ranged from 4-25°C. During the 10 day sample period temporal variation in air temperature at a nearby weather station had a similar range. Isotherm plots reveal a heterogeneous …
