Abstract:
In recent years, on an international level, are frequently used protein
hydrolysate, from natural plants or animal in fertilizers composition, these
representing substances with chelated micro-nutrients properties important
for plant metabolism, but also with the fitostimulator role. A priority of
Romanian research is to use a protein hydrolysates to obtain various
compositions extraradiculara application of fertilizers. Researches were
conducted for obtaining agrochemicals and testing of a liquid fertilizer NPK
or NK with microelements (Fe, Cu, Zn, Mn), secondary (Mg, S) and protein
hydrolysates chelated. There are presented chemical characteristics of
experimental fertilizer that have been tested agrochemical in vegetation on
tomatoes. The paper presents results of agrochemical testing performed in
vegetation house, new variants of fertilizer composition with opportunities to
use both in classic agriculture and ecological.
