| dc.description | Different models for studying the interrelation of geomorphic and pedologic processes active in soil development are discussed in this article in order to determine the different plant height and yield of sunflowers at different landscape positions. Sunflower production in North Dakota has increased greatly from 1964-74. Soils with widely differing properties have been utilized in their production. Among factors which influence sunflower yields are salinity and
plant population. Slope-profile components can be defined in closed systems as summit, shoulder, back slope, foot slope
and toe slope. Soil properties follow systematic patterns of distribution on this landscape. Properties such as organic carbon content, bulk density, texture,
salinity and pH vary with landscape position in a
predictable and repeating manner.
Knowledge of these relationships on a hill slope can aid in understand. The degree with which geologic processes of erosion
and sedimentation affect soils, their properties and crop response depends on landscape position. It is likely these geologic processes and the pedologic reflection of these processes will exist on other similar’ landscapes and under similar conditions present in North Dakota. | |
