An Examination of Land Preparation Methods to Alleviate Common Issues Associated With Pipeline Reclamation
Abstract
Post-seeding land preparation methods can improve reclamation success; however, limited research is available for the Williston Basin. A field study evaluated four treatments: land imprinting, hydromulch, straw crimping, and the combination of hydromulch and land imprinting for their abilities to reduce simulated rainfall runoff and sediment losses and for their ability to promote plant growth. Straw crimping reduced total runoff and may likely be the best option for providing surface cover. However, vegetation establishment was found to be not significant among the treatments. Additionally, a laboratory study examined seven soils for their penetration resistances (PR) across variable water contents (Θg) and bulk densities (Bd). Overall, as Bd increased so did PR, with increases in Θg diminishing PR increases, yet still building strongly correlated relationships (r2 > 0.90). These results will enable reclamation specialists to better define soil conditions and methods for improving soil water retention and overall soil function.
