Abstract

[eng] Farmers' practices and fertility of environment . The concept of cropping system is the analysis tool of crop practices for modern agronomist. But, to be able to talk about environment fertility, it is necessary to refer to potentialities and to the technological means which are used. There is not a fertility in itself but in reference to practised cropping systems in a given environment. Through combining crop practices in time and space, farmer's fertility management is dynamic. But new points of view are crucial, on the one hand because of the emergence of bad induced effects (pollution...), on the other hand because requirements about productions quality become widespread. The result is that fertility management answer more and more to constraints external to the farm. It is a very new situation. [fre] Le concept de système de culture est l'outil d'analyse par l'agronome moderne des pratiques culturales. Mais pour parler de fertilité du milieu on doit se référer aux potentialités et aux moyens technologiques mis en œuvre. Il n'y a pas de fertilité en soi mais en référence, pour un milieu, aux systèmes de culture pratiqués. En combinant dans le temps et dans l'espace ses pratiques culturales l'agriculteur a une gestion dynamique de la fertilité. Mais de nouveaux regards sont nécessaires. D'une part à cause des effets induits pervers (pollution...), d'autre part parce que les exigences de qualité des productions se généralisent. Il résulte de tout cela que la gestion de la fertilité répond de plus en plus à des contraintes « externes » à l'exploitation. C'est une situation très nouvelle.
