Soil biological quantity and quality parameters of grasslands in various landscape zones
In three landscape zones of a permanent grassland catchment (discharge zone, D; transient zone, T; and recharge zone, R; Crystallinicum, Czech Republic), soil moisture by volume (θ) and soil biological quantity and quality parameters, e.g. oxidizable C (Cox), hot water soluble C (Chws), microbial bi...

description | In three landscape zones of a permanent grassland catchment (discharge zone, D; transient zone, T; and recharge zone, R; Crystallinicum, Czech Republic), soil moisture by volume (θ) and soil biological quantity and quality parameters, e.g. oxidizable C (Cox), hot water soluble C (Chws), microbial biomass C (Cmic), nitrification (NITR), aerobic N mineralization (MIN) and basal respiration rates (Rbas), metabolic quotient (qCO2: Rbas/Cmic) and microbial quotient (Cmic/Cox) were estimated in the surface soil layer. We found out positive correlation of Cmic and Cmic/Cox with θ, or NITR, MIN, Rbas and Cmic with Chws, but no relationship between θ on the one hand and NITR, MIN, Rbas or Cox on the other. The wettest zone D with extremely low pH displayed the highest Cmic and Cmic/Cox (1081 mg/kg, 5.29%) and the lowest qCO2 (31 µgC/day/mgCmic). Soil drought in zones T and R reduced Cmic and Cmic/Cox (939, 1029, and 3.72, 3.83, respectively) and augmented qCO2 (42; 51). Rainfall following a prolonged dry period reduced MIN and NITR in permeable zone R as a result of fast microbial regeneration (average in D: 2.24; 2.48 kg N/ha/day, T: 2.62; 2.82 kg N/ha/day, R: 1.51; 1.95 kg N/ha/day). |
