The effect of thiosulfate on phosphorus availability and uptake by plants

Abstract

A growth chamber experiment was conducted to examine the effect that banding urea or a thiosulfate source with monoammonium phosphate had upon fertilizer phosphorus uptake and dry matter yield of barley and rapeseed. For barley, fertilizer phosphorus uptake and dry matter yield were significantly increased when a thiosulfate source was banded with monoammonium phosphate, but not when urea was banded with monoammonium phosphate. Fertilizer phosphorus uptake and dry matter yield of rapeseed were not significantly affected by banding either a thiosulfate source or urea with monoammonium phosphate.

Double Coating as a Novel Technology for Controlling Urea Dissolution in Soil: A Step toward Improving the Sustainability of Nitrogen Fertilization Approaches

“…Thiosulfate compounds are among the most effective inhibitors and not only inhibit the nitrification process but also have an indirect effect on reducing the urease activity (Modolo et al, 2018). Thiosulfates (e.g., sodium and ammonium thiosulfate) are eco-friendly compounds with multiple agricultural applications, including sulfur nutrient supply [25], heavy metal stabilization [26,27], and the acid solubilization of phosphorus and micronutrients [28,29].…”
