Available in PDF, EPUB and Kindle. Book excerpt: L'ouvrage propose aux acteurs de la filière agricole les clefs de la mise en œuvre d'une fertilisation raisonnée, appliquée aux grandes cultures et aux prairies. Après avoir rappelé, le caractère unique des lois de l'agronomie, applicables à toutes les formes de production agricole, les auteurs abordent : - les cycles biologiques fondamentaux des éléments qui contribuent à la nutrition des végétaux, - le calcul de la fertilisation, en fonction de l'offre du sol, des objectifs de production et des interactions entre les sols et les plantes, - les moyens (notamment analytiques) dont l'agriculteur dispose pour déterminer les apports en fertilisants nécessaires ainsi que les modalités de leur application, - les aspects de la fertilisation dans différents contextes environnement, territoires, extensification, économie, qualité, réglementation. La pratique de la fertilisation, longtemps dominée par les seules contraintes technico-économiques, a considérablement évolué au cours des 50 dernières années, valorisant le progrès des connaissances scientifiques, accompagnant les exigences des consommateurs et la prise en compte des contraintes environnementales. A l'heure où l'agriculture raisonnée devient un concept familier du grand public, le COMIFER a souhaité qu'un point complet et précis soit réalisé sur les moyens disponibles pour le développement d'une fertilisation compatible avec une agriculture durable, respectueuse de l'environnement. Ce guide met à la disposition du monde agricole un recueil de références actualisé.
