Abstract: A nitrification inhibitor treatment used as a soil mangement tool on grazed pasture soils. The treatment includes the application of nitrification inhibitors in solution form and/or line particle suspension form and/or in crystalline form to treat the whole area of grazed pasture soils to: reduce nitrate leaching; reduce nitrous oxide emissions; reduce postassium, calcium and magnesium leaching; and increase pasture production in both the animal urine patch areas and non-urine patch areas. The nitrification inhibitors can be applied in conjunction with irrigation water, by a spray vehicle or in a similar way to the application of agricultural chemicals.
