  1. Amend the soil with formulated chemical compounds

    A replicated study in 2009 on loam, silt-loam and sandy loam soils in South Island, New Zealand (Di et al. 2009) found that adding the nitrification inhibitor dicyandiamide reduced nitrate loss by an average of 59% across different soil types and contrasting rainfall conditions. Soils in Canterbury, West Coast and Southland regions were fertilized with cow urine at a rate of 1,000 kg N/ha. Dicyandiamide was applied to half the soils at 10 kg/ha following urine application, and under two rainfall conditions (1,100 and 2,200 mm/year). There were four replicates of each treatment and soils were sampled in large (0.5 x 0.7 m), undisturbed sections.
