"In some regions, the producer is in a comfort zone that is difficult to leave," states Nahuel Reussi Calv.

The phenomenon of yield gaps is something that soil nutrition specialists have been warning about for a long time. As a general rule, it means that in the main crops, between 20 and 40% less is produced than what could potentially be produced, due to various factors but, above all, due to the lack of articulated management strategies and poor fertilization. Nahuel Reussi Calvo is a Conicet researcher who always insists that, “although it sounds utopian,” efforts must be made to close these gaps. For that, he argues, the focus must be on the data provided by soil measurements, because only then can the right decisions be made in terms of efficiency. “The big problem is that there is little data, and that is the great challenge we face who do research and extension work,” the specialist noted when interviewed by Bichos de Campo. In truth, many entities, such as CREA, have their own systematized databases, which allow decisions to be anticipated and predictive models to be fed, but, ...
