Title: Topographic Position Effects on Soil Water and Wheat Yields on Reclaimed Minelands
Author: Schroeder, S. A.
Description: North Dakota is a semi-arid area. Agriculture and high yields are dependent upon the amount of water available to growing plants. Available soil water at planting time along with growing season precipitation are both correlated with yields especially with those of small grains. The topography of growing contexts especially reclaimed mine areas affects the redistribution of water amongst landscape positions. Run-off of precipitation as well as saturated and unsaturated flow in the soil in soil profiles result in uneven distribution of available water in landscapes. Mining activities disrupt normal water collection and distribution activities. The soil depth may be altered as well. Regulations in North Dakota require that land disturbed by mining activities be reclaimed to productivity rates equal to or better than those prior to mining. In this writing, two reclaimed mining areas were studied. The two reclaimed areas displayed significant topographic position effects on available water resources at planting times and at wheat yields.
