Abstract
The aim of the present study was to compare the effects of mineral and liquid organic fertilisers on the accumulation of nitrate and ammonium nitrogen in a clay loam Endocalcari Endohypogleyic Cambisol and on chlorophyll content in common winter wheat (Triticum aestivum L. emend. Fiori et Paol.) leaves. Ammonium nitrate was used as a mineral fertiliser. Liquid bio-fertilisers – pig slurry and anaerobic digestate – were studied with and without nitrification inhibitor (DMPP). In spring, after resumption of winter wheat vegetation, the investigated fertilizers were applied at N120 rate. Soil samples were taken from the 0-30 and 30-60 cm soil depths one and a half months after fertilisation. Dry weather prevailed during the study period. Results showed that the mineral nitrogen content in the soil varied depending on the fertiliser used and a slight effect of DMPP was observed. Compared to the unfertilised treatment, the highest and significant increase in mineral (nitrate and ammonium) nitrogen content was determined in the deeper soil layer of the mineral fertilisation treatment. Neither nitrogen rate nor fertilisers of different composition had influence on leaf chlorophyll content.
