This paper will present the results obtained on the reddish preluvosoil, in the period of 2014-2016, situated on the experimental field of the Department of Soil Sciences, at Moara Domneasca. The wheat crop is part of a crop rotation wheat-barley-sugar beet. The experience is a two-factor concept, organised in three repetitions, with the next factors: a - organic fertilization and b - mineral fertilization. The research aims to find the perfect balance between the used resources and the best results, in an economic point of view. As natural fertilizers were used plant residues and manure, nutrient needs are supplemented with mineral fertilizer based mostly on nitrogen. The research has shown, that nitrogen fertilization with organic and mineral nitrogen increases wheat production along with profits. In terms of production, the best is a3 – b4 (40 t/ha leaves an pices of sugar beet and a dose of N150), but, economically, the variant a1-b4 (unfertilized organically with a dose of N150) gives the best outcome for the farm.
