In the period 2001-2003 a field experiment was carried out at the Fruit Growing Institute- Plovdiv on alluvial-meadow soil for studying the effect of the soil herbicides napropamid, pendimethalin, terbacil and metolachlore on the content of mineral elements in the leaves of yellow plum seedling rootstocks. The results obtained showed that significant changes in the mineral composition of the leaves of the yellow plum seedling rootstocks were not established after treatment with the soil herbicides included in the study. There was a tendency towards an increase of their content after applying the soil herbicides, which was better expressed in the plants of the variants treated with napropamid - devrinol 4 F-400 ml/da, pendimethalin - stomp 33 EC-400 ml/da and terbacil- sinbar 80 WP-100g/da.
