Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity WHO International Programme on Chemical Safety Der wertvollste Bestandteil der SchriftThe purpose of our present work is to review the fundamental studies on inhibition of soil urease activity and the applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity. The general literature on these topics covers 65 years, and the patent literature comprises a period of nearly 40 years. Studies related to inhibition of soil urease activity were performed in a great number of countries' well representing
