The use of sewage fertiliser products on arable land - requirements from the farmers' perspective

Abstract

The aim of this paper was to discuss farmers' requirements for using sewage products as fertilisera on arable land. A quistionnaire followed up with interviews was used in a watershed area close to Stockholm. The study also included calculations of the cost to farmers of handling different sewage products. Farmers were most interested in source-separated human urine and precipitated septic tank sludge originating from on-site treatment. A high concentration of plant nutrients was important for farmers, as well as good hygiene wuality of the product and a low content of heavy metals. However, the most important factor for farmers was that the expenses for e.g. collection, transporting, storage and spreading were covered
