Sažetak
The problem of compactness of heavy soils could be surpassed by mole drainage and subsoiling. The aim of this study was to investigate effects of mole drainage and subsoiling (treatment) on available nitrogen content in the soil profile, as well as, its uptake by maize and sunflower, on calcareous clay chernozem soil, in rainfed cropping during 2009. The total N output by plants, leaching and evaporation in control (without mole drainage and subsoiling) was higher by 15% in sunflower and by 43%, in maize. Moreover, N deprivation by leaching and evaporation during the growing season of sunflower was 338.13 kg N ha-1 in control and 287.37 kg N ha-1 in the treatment, while it was 475.03 kg N ha-1 in maize in control and 268.63 kg N ha-1 in treatment. The observed situation affected the plant growth during the growing season – biomass of both, sunflower and maize was higher, but the dry weight was lower in control. The N uptake by crops during the growing season was better in the treatment, resulting in the grain yield increase of 10% in maize and of 9% in sunflower.
