Horizontal transfer of nutrients in long-term field experiment
Abstract
The horizontal movement of soil phosphorus and potassium was investigated by soil sampling in two long-term field experiments at Aas Norway. After 30 years with 3-4 years ley and 3-4 arable crops in 6-8 years rotations the transfer of P and K was estimated roughly 5-6% after correcting for the border areas. After 10-15% carry over was measured within the border areas.
