Calculate the relative impact of field properties given its position in the landscape

Estimate the relative ranking of field properties given their contribution to nutrient losses to aquatic ecosystems as well as nutrient and water efficiency. A high rank is indicative for the number of opportunities to improve soil quality and land use.
