Influence of Elemental Sulphur, Oxalic Acid, and Phosphoric Acid as Acidulating Agents on Phosphorous Dissolution from Rock Phosphate

Fidelis W. Githua, Winnie Ntinyari, Nicholas K. Korir & Joseph P. Gweyi-Onyango · Journal of Agriculture and Ecology Research International · 2019

Phosphorous is a limiting mineral element in crop productivity due to its less availability and fixed form in the soil. Due to its agricultural benefit, most farmers seek for alternative method to supply phosphorous in sufficient amount in the farming systems. Although the solubl...
