The objects of the studies were soil samples taken from a field experiment carried out at the Experimental Farm of Uhrusk belonging to the Agricultural University in Lublin (Poland). Those samples were taken in 2000 after the harvest of spring triticale sown in a field experiment after potatoes, sowing peas and after triticale. It was shown that the greatest number of weed diaspores in the soil after the harvest of spring triticale occurred in the site where it was sown after triticale, while a smaller number by 29.7-31.3 percent - after potatoes and peas. Significantly more diaspores were stored in a 1-1 cm soil layer, while less by 30.2-33.6 percent in the layers of 0-1 and 10-25 cm. In the site where spring triticale was sown after potatoes, the most numerous were the following diaspores: Chenopodium album, Amaranthus retrojlexus, Stellaria media, Galium aparine, Viola arvensis and Fallopia convolvulus. On the plots after peas the diaspore bank was formed by the following: Chenopodium album, Stellaria media, Amaranthus retrojlexus, Avena fatua and Fallopia concolvulus. In the site after triticale the most numerous were, Viola arvensis, Stellaria media, Chenopodium album, Avena fatua, Fallopia convolvulus, Galium aparine and Amaranthus retrojlexus
