Summary

Effect of nitrification inhibitor – “N-Serve” on transformation of fertilizer nitrogen in the soils – plants system (with experiments of stable isotope, ¹⁵N)

Inhibitor nitrification influenced on balance of fertilizer nitrogen in “soil-plant” system: increase in applied coefficient of fertilizer nitrogen and supplementary assimilation for soil nitrogen. In the experimental conditions the loss of fertilizer nitrogen by leaching NO₃ and denitrification decreased without affecting water quality.
