The College of agriculture exhibition is an important initiative promoting Tanzania`s rich Agriculture sector and presenting farmers, companies and investors a great way to explore the huge untapped potential inovations and technologies of this country.
The Guelph Permeameter is used to obtain accurate measurements of hydraulic conductivity, soil sorbtivity and soil matrix flux potential. These three factors govern how liquid move through an unsaturated soil profile.
Recent significant advances in both the theoretical and the practical techniques of measuring the soil hydraulic conductivity have been made by the University of Guelph. This has resulted in the development of the Guelph Permeameter uitlizing the Constant Head Well Principle.
This lightweight instrument is portable, reliable and simple to use. Depending on the soil type, accurate results can be obtained in 1 to 2 hours using only 2.5 litres of water.
