The study deals with the new Econov section control evaluation. It shows first the followed methodology and its three steps, from continuous data acquisition of spreader parameter states to spread pattern characterization, and finally distributed rates into the field. Obtained maps results are given as well for spreader parameter states as for final obtained field rates. Performed in many cases of field shape, fertilizer types, with section control or not, the study gives some quantified results about induced spreading defaults and also on benefits to use section control devices. It particularly highlights the first order importance of field shape and the regularity of spaces between tramlines importance, firstly to obtain the desired rate (global gain) and secondly to minimize fertilizer rate dispersion and maximize crops yield and quality. In a second level, fertilizer performance is also presented, mainly by the dispersion reduction it allows when transverse curves are triangular. In a more precise analyze, benefits to use section control is also evaluated regarding the position in the field (main field application vs boarder application).
