Abstract

[fre] L'efficacité économique ne doit pas rester l'unique critère des choix technologiques : lia préservation et .la valorisation des ressources du milieu doit devenir une préoccupation prioritaire. . La plante cultivée est la principale ressource biologique mise en jeu dans le processus de production. La plante récoltée vise à satisfaire un besoin ide l'homme. Elle est aussi un instrument de mise en valeur du milieu. . L'outil que constitue la plante doit sans cesse être amélioré et adapté aux conditions de sa mise en œuvre. Pour créer des combinaisons génétiques nouvelles, des méthodes de plus en plus compllexes sont élaborées. . L'amélioration des végétaux est une technique biologique dont l'influence restera longtemps prépondérante Les facteurs physiques et biologiques agissant au sein du sol et du climat doivent être utilisés pour en tirer le meiilleur parti. La lutte contre toute dégradation du sol (érosion...), contre les accidents et parasites, est un aspect essentiel de la valorisation du potentiel de production. Le choix et lia imise au point de techniques douces devront permettre de concilier l'efficacité et la protection du milieu. . En conclusion, entretenir et améliorer lies capacités des sols, conserver et utiliser au mieux l'eau disponible, restent les principales voies du progrès en agriculture. [eng] Agricultural technology based on the use and management of natural resources - Economic efficiency must not be the only criterion in technological choices. The preservation and the up-grading of the resources of the environment must become a priority concern. . The cultivated plant is the main biological resource at stake in the production process. The harvested plant is intended to satisfy a human need. It is also a means of improving the environment. . The plant, as an instrument, must constantly be improved and adapted to the conditions of its cultivation. In order to create new genetic combinations increasingly complicated methods are worked out. . The improvement of plants is a biological technique with a long-lasting influence. The physical and biological factors at work within the soil and the climate must be used to best advantage. The struggle against any kind of deterioration of the soil (erosion), against accidents and parasites, is an essential aspect of the increased potential and production value. . The choice and perfecting of gentle techniques should enable efficiency and the protection of the environment to be reconciled. . In conclusion, safe-guarding and improving the potential of the soil, preserving and making best use of the available water, are the main means of making progress in farming.
