How Fertilisation Affects Distribution Of Carbon And Nutrients In Vineyard Soil?

The effect of fertilisation on C and N, P, K nutrients distribution in the Rendzic Leptosol in locality Nitra-Dražovce was studied. We evaluated the following treatments of fertilisation: (1) G (non-fertilised), (2) FYM (farmyard manure – dose 40 t/ha), (3) G+NPK3 (grass + 3^rd intensity of fertilisation for vineyards), and (4) G+NPK1 (grass + 1^st intensity of fertilisation for vineyards). The soil samples were taken in spring during the years 2008–2015. Obtained results showed that the content of organic carbon (C_org) decreased in the following order: G+NPK1 > FYM > G > G+NPK3 and content of total nitrogen (N_t) decreased in the following order: FYM > G+NPK3 > G+NPK1 > G. The application of NPK in the 1^st intensity of fertilisation for vineyards and added FYM build up a C_org at an average rate of 370 and 229 mg/kg/year, respectively. On the other hand, contents of N_t due to fertilisation declined in FYM, G+NPK3 and G+NPK1 at an average rate of 53, 22 and 20 mg/kg/year, respectively. Available P and K contents were also increased after the fertilisation of FYM and NPK. Added fertilisers (G+NPK3) significantly build up a P at an average rate of 10.2 mg/kg/year.
