Summary
In the Nebraska Sandhills region (central USA), crop cultivation under center-pivot irrigation was widespread during the 1970’s. Many marginal sites have subsequently been abandoned, leaving large areas of exposed sandy soils. Revegetation is needed to prevent further erosion and expansion of these areas. This experiment, undertaken in Custer County, assessed the effects of tillage, irrigation level, seed coating and species (four native perennial bunchgrasses) on grass establishment.
On abandoned cropland, tillage treatment comprised plots shallow disked a day prior to seeding, or untilled (forage sorghum stubble residue remaining). Irrigation (in tilled and untilled sub-plots; 2 replications) comprised water applied in three equal amounts (15-17 July, 21-22 July, and 27-29 July, application dates based on moisture stress) in 60 m width circular bands at a total of 0, 2 or 4 cm of water.
