Apply herbicide before seeding/planting
A replicated, randomized, controlled study in 2005–2008 in two former agricultural fields in South Dakota, USA (Bahm et al. 2015) found that spraying with herbicide followed by sowing native grass seeds increased the cover of sown grass species and reduced the cover of unsown grass species compared to plots that were seeded but not sprayed with herbicide. After three years, the average cover of sown grass species was higher in plots where herbicide was sprayed and seeds were sown (57–70%) than in unsprayed plots where seeds were sown (1%). The opposite was true for unsown grass species (sprayed plots: 1–3%; unsprayed plots: 59%). In 2005, four 3 x 10 m areas were established in two fields where soybeans Glycine max were previously grown. Herbicide (‘Roundup’ containing imazapic and glyphosate) was randomly applied to three areas, while in one area herbicide was not applied. Two weeks later, a seed mix containing native grass seeds was sown in all areas. Vegetation cover was measured in eight 1-m2 plots in each of the four areas at the end of the growing season in 2006–2008.
