Is there reason to adapt fertilizer rates along field boundaries?

By analysis of a national field polygon database, it was found that about one fourth of Sweden’scropland (fields >10 ha considered) is within 20 m of a field edge. In 16 observation transectsbordering forest or other fields, it was found that winter wheat (Triticum aestivum L.) yields weresignificantly smaller in field margins compared with field interiors. Effect sizes were larger alongwoody vegetation; yields were about 2 t/ha smaller at 8 m from the edge compared with at 26 m fromthe edge. It was concluded that field margins deserve special attention in site-specific management.
