Add fertilizer to soil before or after seeding/planting
A replicated, randomized, paired, controlled study in 2000–2001 in a mining area in the Northwest Territories, Canada (Reid & Naeth 2005) found that adding fertilizer and sowing of seeds did not alter vegetation cover compared to seeding alone. Vegetation cover did not differ significantly between areas where fertilizer was added and seeds were sown (2–6%) and areas where no fertilizer was added but seeds were sown (4%). In August 2000, blocks were established containing four 5 × 2 m plots (number of blocks unclear from study) on areas of mining waste. Gypsum (2,173 kg/ha), rock phosphate (2,080 kg/ha) and calcium carbonate (1,667 kg/ha) were each added to one plot in each block, while one plot received no fertilizer. All plots were sown with the seeds of seven native grass species. In August 2000 and 2001, vegetation cover was assessed using three 50 × 20 cm quadrats/plot.
