Soils Data for North Dakota Mined Land Reclamation Experiments in the 1970’s Using Soil Respreading

In the early 1970’s, it was determined that the most feasible way to reclaim lands disturbed by coal surface mining in the Northern Great Plains region was through the respreading of salvaged soil. In 1974, scientists at the Northern Great Plains Research Laboratory of the Agricultural Research Service -- U. S. Department of Agriculture (USDA-ARS) initiated two experiments designed to determine the thicknesses of respread soil necessary to restore productivity to difficult-to-reclaim sodic minespoils in central North Dakota (ND). In both experiments, motorscraper and other earthmoving equipment was used to construct wedge-shaped masses of subsoil materials over leveled minespoils and then to cover these with uniform thicknesses of topsoil material. Topsoil consisted of predominately A horizon material from Haplustoll soils, and subsoil consisted of B and C horizon material.

In one experiment near the town of Stanton ND, a subsoil wedge was constructed on leveled minespoil and consisted of 12 long contiguous blocks of material (which were the main plots), three replications of four topsoil thickness treatments. For each replication, three of the main treatment blocks consisted of subsoil material, and one was a 3:1 subsoil – topsoil mix. The topsoil treatments consisted of no topsoil, 20 cm, 60 cm, and no topsoil on the mixed soil block. Each main treatment block was split into four long strips and seeded to crops of alfalfa, crested wheatgrass, spring wheat, and warm-season grass mix. The wedge was 240 m long, 65 m wide, and 2.1 m high at the summit.

In another experiment near the town of Zap ND, a double subsoil wedge was constructed on leveled minespoil and consisted of six long contiguous blocks of material (which were the main plots), two replications on each side of the wedge, for a total of four replications with three subsoil quality treatments. The subsoils varied in soil texture, salinity and sodicity. The wedge was covered with a uniform 20 cm thickness of topsoil. Each main treatment block was split into four long strips and seeded to the same crops as the Stanton site with the exception of warm-season grass mix, which was replaced with Russian wildrye. The double wedge was 124 m long, and about 50 m from each toe to summit for a total width of 102 m and was 2.1 m high at the summit.

Intended use

The soil properties data were collected as part of one of the first experimental mined land reclamation experiments in North America that used respreading of salvaged soil. This data, collected in the period 1976 to 1981, should be of interest to scientists conducting research on long-term soil change and development.

Use limitations

Data are specific to respread, salvaged soil.
