Description
| - The Plešné Lake watershed is covered with an undeveloped ~0.2 m deep organic rich soil (38%), and ~0.45 m deep podzol (29%) or spodo-dystric cambisol (27%). Stones >2mm in diameter, fine soil, and moisture contributes on average 49%, 28%, and 23% to the total soil pool. Fine soil is sandy (~75%) with a low (~2%) content of clay and its watershed weighted mean (WWM) pool is 92 kg/m2. The WWM pools of C, N, S, and P are 936, 39, 1.6, and 1.9 mol/m2, resp. Soil pH is low, with the lowest values (2.5-3.1) in A horizons and highest (3.2-4.4) in the Bs and C horizons. The WWM cation exchange capacity is 129 meq/kg, 15% of which is base saturation (Ca, 9%; and Mg, Na, and K ~2% each), and is dominated by exchangeable Al (57%) and protons (28%). Average concentrations of C, N, and P in soil microbial biomass is 0.7%, 2.7%, and 11% of their total contents. Moreover, data on C and N mineralization rate, nitrification potential, and extractable Fe, Al, P, and S, are reported.
