Sažetak
The research objective was to determine, in the period from September 2009 to August 2010, excess water (drainage discharge) in drained soil, type Gleyic Podzoluvisol, at different drainpipe spacings (15 m, 20 m, 25 m and 30 m, with contact material gravel and average depth of 1 m) and to compare it with excess water in soil mathematically calculated by the Thornthwaite and Palmer methods. The total amount of precipitation in the mentioned period was 1159.5 mm. Excess water measured with limnigraphs and amounted to 350 mm at drainpipe spacing of 15 m, 340 mm at 20 m spacing, 328 mm at 25 m spacing, and 320 mm at 30 m spacing. Excess water in soil calculated by the Thornthwaite method was 424.4 mm and by the Palmer method 404.2 mm. The obtained results clearly show that there are differences both between the tested drainpipe spacings and between the results calculated by the Thornthwaite method and the Palmer method. Measured data at all drainpipe spacings were smaller than mathematically calculated by both methods. Measured and calculated excess water in drained soil depends on the total amount of precipitation, its distribution, drainpipe spacings, crop type and the mathematical method used.
