How many plants are used for phytomonitoring?
The phytomonitoring interpretation technique is mainly based on the analysis of trends, which are much more representative for uniform crop than absolute crop characteristics. For example, instant temperature of several leaves may differ in a few degrees centigrade while the response to lower humidity will be uniform: elevating transpiration will reduce temperature of all leaves. Usually a phytomonitor set incorporates a single set of environmental sensors and double set of main plant related sensors. It means that only two plants may be used as driving ones at a uniform plot. By the way it gives a unique opportunity to test some new treatments or regimes only on driving plants at first, before application on a whole crop. 3.
