Hnojení – novodobý nástroj nebo odvěká součást zemědělství?

Fertilizer application – modern time tool or integral part of the agriculture since its beginning? by Michal Hejcman and Vilém Pavlů.

Fertilizer application is frequently considered to be modern time tool increasing crop production. The aim of this paper was to briefly decribe history of fertilizer application on agricultural land and to conclude wheather the fertilization is modern time tool or integral part of the agculture since its beginning. Fertilization can be divided into direct (application of fertilizers) and indirect (support of legumes fixing atmospheric N2). Positive effect of organic and several mineral fertilizers (wood ash, gipsum and lime) as well as the use of legumes has been provably known since Roman times. Based on our practical experiences with grazing and fertilizer experiments, we suppose that the use of direct and indirect fertilization can be integral part of the agriculture since its beginning. Although mineral fertilizers has been used for hunderds years, principles of mineral plant nutrition were first explained by Carl Sprengel and by Justus von Liebig in the first half of the 19th century.
