- Library Collection RecordThe relationship of soil and vegetation factors to soil loss and runoff were examined near Center, North Dakota on reclaimed mine-land pastures (Cabba Soils) and adjacent native rangeland (Sen Soils…Publication Date 1969

- Library Collection RecordThe gaming theory is used to model outcomes of grassland use for grazing by cooperative farmers and non-cooperating farmers. Models account for grassland dynamics and assume each farmer maximizes…Publication Date 1969

- Library Collection RecordDuck nest success on 12 pastures grazed under a once-over rotational grazing system and 12 pastures grazed season-long was measured in the prairie pothole region of southern Saskatchewan. In 1995 and…Publication Date 1969

- Library Collection RecordThis study was conducted to further determine relationships of soil and vegetation factors to soil loss and water runoff from reclaimed pastures and rangeland in Nebraska. Results showed that soil…Publication Date 1969

- Library Collection RecordThe total biomass response of Stipa occidentalis to elevated CO2 was similar (averaging 18% increase in biomass) to the response found for other grassland species. However, the increase in total…Publication Date 1969
