About the Author

Professor Mukhtar Abduyev (1926 - 79), Doctor of Agricultural Science, was respected across the USSR for his work on the amelioration of saline and polluted land. He had a lifelong connection with the Azerbaijan SSR's Institute of Soil Sciences and Agricultural Chemistry, founding and leading the country's first Soil Reclamation Laboratory there. He also inspired many talented students at the Azerbaijan State University and other institutions. In 1970 he was awarded the USSR's medal for Valorous Labour.
