Nutrient leaching from clay soil monoliths with variable past manure inputs
Abstract Overall, arable soils in Sweden are currently generally close to phosphorus (P) balance, but excessive P accumulation has occurred on animal fur farms, i.e., those rearing mink ( Mustela vison ) and foxes ( Alopex lagopus and Vulpes vulpes ). Manure P from these farms has sometimes regarded...
