“…The results proved that in this soil, too, the retarding effect of PPDA on urea hydrolysis, ~ + accumulation, and pNH3 lasted only a few days after both first and second applications of urea at each rate. Phongpan et al (1988) performed a pot experiment using a wetland soil (clay, pH 5.1) from Thailand. Pots filled with soil to reach a total dry weight of 4 kg/pot were flooded with demineralized water, puddled and allowed to stand overnight.…”

I Preface The 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 all the continents. Full texts of the papers describing these studies were published in one of 18 languages·'. The literature data reviewed are structured into 10 chapters, 81 subchapters, and 224 sections. The bibliographical list consists of 830 papers cited. ·In alphabetical order:
