Title: Productivity of Prime, Nonprime and Reclaimed Soils in Western North Dakota
Author: Doll, E.C.; Schroeder, S.A.
Description: State and federal stripmine reclamation laws require the separate handling of top soil and subsoil from prime land. Prime land soil materials must be removed and separated from on-prime materials and must be broadcast on approximately on their original location. the development of prime soils in western North Dakota is apparently due to moisture differences that result from topographic locale than due to differences in parent materials. Higher overall productive levels on reclaimed land might be attained by uniformly re-spreading all suitable materials over land reshaped to the most effective topographic configuration. The study written about in this paper was performed to identify the factors related to productivity of undisturbed prime and non-prime soils and similar areas of reclaimed soils. On undisturbed prime and non-prime soils, yields were dependent upon the amount of available water at planting times in addition to the amount of rainfall during the growing season. Until the soil structure begins to re-establish in disturbed soils, giving rise to more favorable conditions for porosity, water infiltration and root penetration, optimum crop yields can not be expected. Addressing the varying differences in soil textures may play an important role in re-establishing desired yields once again. Critical are the chemical and physical characteristics of the soil materials and the restoration of a post-mine topography, which includes prime land areas in which soil moisture levels can develop which are similar to those in prime soils before mining activities.
