Potential of ammonium thiosulfate and potassium thiosulfate to inhibit nitrification in soils

open access: yesSoil Science Society of America Journal, Volume 89, Issue 3, May/June 2025.
Abstract Nitrogen use efficiency by crops can vary according to soil properties and environmental conditions. Nitrification inhibitors show potential to improve efficiency of fertilizer N use by keeping N in the ammonium form, decreasing leaching, and denitrification. The objective of this study was to evaluate the effectiveness of ammonium thiosulfate
