Abstract
A three-year field trial was conducted with potatoes on sandy soil to study the effect of traffic-induced soil compactions and N fertilizer placement on crop yield and N utilization. The observed tuber yield lo ss due to soil compaction in the wheel tracks was significant only in one year. Band application of 70 kg N.ha-1 as ammonium sulphate offset these adverse effects in two of the three experimental years and impr oved N utilization by 13-29%.
