During my full career I had a strong interest in land and water measurements. Both in the methodology as well as in suitable equipment. For that reason I worked together with Royal Eijkelkamp from 1990-2015. This international company provides equipment and services in the domains: land degradation, food security, pollution, urbanisation, natural resources and land development, (https://www.royaleijkelkamp.com/en). On their web site you will find information about products, services, departments, distributors and much more. It is possible to download all available product information and manuals as PDF. Eijkelkamp has an excellent showroom in Giesbeek, only 30 minutes from Wageningen. My students as well as many other student groups visited this showroom and the factory every year. You are most welcome to join.
26 April 2018: it has pleased the King of The Netherlands, King Willem Alexander, to decorate Fons Eijkelkamp as knight in the ‘Orde of Oranje Nassau’. He received this honour for his unprecedented devotion to the Water Entrepreneur project through the Eijkelkamp Foundation. The ceremony was at 10.30 am in the town hall in Zevenaar (the commune where to Giesbeek belongs) and the decoration was pinned up by the Mayor in the presence of family and best friends.
Combining my work for Wageningen University & Research with my work for Royal Eijkelkamp created a win-win situation. The university profited from high quality standardized equipment and Eijkelkamp profited from know-how, new ideas and a critical review by scientists. Often new equipment was tested by staff of Wageningen University & Research. Together with Eijkelkamp we developed a mini-rainfall simulator for the assessment of soil erodibilty and the saltiphone for measuring wind erosion by particle saltation.
For a critical review of erosion measurement see: (Stroosnijder, L., 2005. Measurement of erosion: is it possible? Catena 64: 162-173).
