Uptake of more important mineral components by common field weeds on loess soils

We have determined the contents of N, P, K, Ca, Mg, Na, Fe, Cu, Mn and Zn in winter wheat, spring barley, sugar beets and winter rape, as well as in the most common weed species infesting these crops. It was established that the percentage of mineral components in the dry matter of the majority of weeds is higher than in that of the cultivated plants. The most dangerous weed species competing with plants for the investigated nutrients were: Chenopodium album, Cirsium arvense, Convolvulus arvensis, Polygonum convolvulus, Sonchus arvensis and Stellaria media.
