The investigations on weeds count and species dynamic have been carried out in certificated biological field in 6-field crop rotation on the Study and Research Farm Vecauce, Latvia University of Agriculture in 2004-2005. The aim of research was to clarify weeds distribution dynamic in organic crop rotation sowings. Crop rotation scheme: (1) triticale/winter rye (for green fertilizer in spring), (2) white mustard (for green fertilizer)/winter rye (for green fertilizer in autumn), (3) potatoes, (4) oats, (5) vetch mix (for green fertilizer) + clover, timothy, (6) clover, timothy (for green fertilizer). Data of changes of weeds count and weeds green mass in organic crop rotation fields were given in 3 tables.
