This report aims to identify objects and possibilities for potato cultivation in Västerbotten County, Sweden, to be sustainable in the future. To obtain background facts a potato consultant was interviewed. Four potato growers, chosen from the Västerbotten County Administrative Board’s list of growers, were interviewed in the study, as well as two growers from KRAVs’ list of certified organic growers in Västerbotten. When growing potatoes, pre-growing is done before they are set. While they grow, weed control, watering and fertilizing is carried out. Chemical biocides are used in potato cultivation to fight weeds, fungus and other pests. Many of the substances are persistent or highly leachable and can cause adverse environmental effects. The results show that most of the interviewed growers regard crop rotation and careful selection of cultivars as important preventive measures. They feel that the use of pesticies has increased and that it is necessary. Few growers use consultants. Increased demand for washed and peeled potatos is hard for the growers to meet. Authorities and independent inspectorates demand extensive documentation, which growers feel are difficult and time consuming. Conclusions are that usage of pesicides can decrease with good crop rotation and selection resistant cultivars. Less demand for documentation could mean more certified or subsidy-taking growers, which in its turn can be beneficial for the environment. Many growers do not think the future for the job is bright. Reducing usage of pesticides is possible if dispersion of risks is carried out by not concentrating on potatos only, but growing other crops as well.
