Abstract. The article gives the data on the soil fertility level and external factors
of environment influence on the dynamics of nitrate and ammoniac nitrogen in sod-
lightpodzolic loamy and sandy soil. Application of both mineral and organic fertilizers
promoted an increase in the mineral nitrogen content in both experiments in relation
to the control.
Keywords: sod-podsolic soils, fertilizers, nitrogen, ammoniac, nitrate,
granulometrical structure.
