The paper presents data concerning the influence of foliar application of some types of complex nutrients (complex liquids with aminoacides and ureids) under the conditions of SCPP Caransebes (Caras-Severin) and ICPP Maracineni (Arges). For apple, plum and sour-cherry trees and raspberry and billbarry bush. The novelty is represented by the apparent degrees of use for yields of the macroelements from foliar nutrients, as well as the productive use degrees of nutrient elements present in soil and in the nutrients applied on soil. The application of different types of foliar nutrients on plants teguments determined significant yield increases for the five species that were studied. They determine high levels of productive use of the nutrient elements from soil and from the foliar nutrients applied on soil. The experimental data emphasize the ecological protection effect of the supplementary fertilization for a foliar stimulation of yields especially on soils with light texture and sloping soils.
