The article deals with the influence of organic and mineral fertilizers applied to agricultural fields in the Belgorod region, on the hydrochemical indicators of small rivers, in particular, nitrogen (N) and phosphates (P). Calculations are made of the territorial load of organic and mineral fertilizers applied to the cultivated areas of the studied areas. A comparative characteristic of the dynamics of organic and mineral fertilizers application in the studied areas of the Belgorod region with the hydrochemical indicators of small rivers located within their limits is carried out. As a result of the correlation analysis, there is no close connection between the dynamics of chemical fertilizers application and the hydroecological situation in the studied regions of the Belgorod region.

Key words: органические и минеральные удобрения, малые реки, Белгородская область, гидрохимические показатели, сельскохозяйственные угодья, загрязняющие вещества, антропогенная нагрузка, водосборные бассейны, organic and mineral fertilizers, small rivers, Belgorod r
