Real time measurement in agriculture.

For economical and even more ecological reasons plants should be provided with nutrients according to their real needs, i.e. over-and undersupply have to be avoided. To guarantee the optimum supply, soil samples are often analyzed for NO3-N. The present sampling and analytical procedure is extremely costly, laborious and time-intensive. Easy to handle and rather inexpensive analytical instrumentation which can be used on-site might therefore offer advantages. Such a system, RQflex-which makes use of quantitative evaluation of test strips- was recently introduced to the market. Different projects in the field of agricultural analysis show that the RQflex is an analytical tool which provides quantitative data with high reproductivity and accuracy. Easy handling, the availability of results within only a few minutes and costs per analysis which are only a fraction of the laboratory method make the RQ-system a powerful analytical tool. This is why the RQflex received the gold medal for innovation during the INTERSIMA 94 in Paris, France.
