Abstract

La présente invention concerne un dispositif de réglage de la quantité d'engrais capable de régler la quantité d'engrais permettant la réalisation de rendements élevés et d'un goût excellent dans la culture de grains. Ce dispositif de réglage de la quantité d'engrais (5) est équipé d'une unité de réglage de la quantité d'engrais (50) qui ajuste la quantité d'engrais, qui est associée au rendement de grains et au goût de grains, sur la base d'une valeur de goût cible pour un goût de grains et d'un rendement cible pour le rendement de grains. L'unité de réglage de quantité d'engrais (50) est équipée d'une unité de calcul de différence de rendement (51) qui calcule la différence de rendement, qui est la différence entre le rendement cible et la performance de rendement réel du grain, et une unité de calcul de différence de goût (52), qui calcule la différence de goût, qui est la différence entre le goût cible et la performance de goût réel du grain. La quantité d'engrais est réglée sur la base de la différence de rendement calculée et la différence de goût calculée.
