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-1, 5.29 %) and the lowest qCO2 (31 µgC.day-1.mgCmic-1). 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 fast microbial regeneration (average in D: 2.24; 2.48 kg N.ha-1.day-1, T: 2.62; 2.82, R: 1.51; 1.95).
