The efficacy of phosphorus and nitrogen soil tests developed for undisturbed soils in North Dakota to predict deficiency of these nutrients and the related corrective measures using commercial fertilizers was evaluated on reclaimed sites with three crops over a 2-year period. Yield responses of wheat, corn, and grass-legume to application of phosphorus and nitrogen fertilizers confirmed a deficiency or sufficiency of each nutrient. The nutrient status predictive capability of the soil tests is considered suitable for reclaimed sites. Rate of nutrient application to correct the deficiency, however, may require adjustment from those utilized for undisturbed sites.
