Wpływ nawożenia na zawartość azotu mineralnego w glebach użytków zielonych i upraw rolniczych o przeznaczeniu paszowym (The impact of fertilization on the mineral nitrogen content in grassland and fodder crop soils)

Abstrakt

A mineral N content (Nmin) in the 60-90 cm layer of mineral and org. soils depending on the N dose in the mineral fertilizer used for grassland as well as for the cultivation of maize and cereal mixes in 2010-2012 was detd. in spring and autumn to find a resp. correlation. The Nmin content and the dose of N fertilizer were positively correlated for (i) grassland on mineral soils, (ii) grassland on org. soils, and (iii) cultivations of maize and cereal mixes on mineral soils. Particularly high correlation coeffs. (higher than 0.8) were obsd. for cereal mixes cultivations. A negative correlation was obsd. only for grassland on org. soils during the autumn sampling.
