Nitrogen fertilizers and soil fertility [PDF]

, 2012
Plodnost zemljišta predstavlja jedan od najvažnijih faktora za uspešnu biljnu proizvodnju i postizanje visokih prinosa. Zaštita i očuvanje plodnosti zemljišta predstavlja najvažniji zadatak i aktuelan problem poljoprivredne struke, jer neadekvatnom tehnologijom proizvodnje, a posebno primenom visokih doza đubriva veoma često dolazi do degradacionih ...

Decomposition rate of organic fertilizers: effect on yield, nitrogen availability and nitrogen stock in the soil [PDF]

, 2012
The nitrogen of organic fertilizers does not fully mineralize within a season, and hence will partly become available in later years. This effect is taken into account for the first year but generally not in later fertilizer applications.
