MARTINEZ-VIERA, R  e  DIBUT, B. New paradigms used to deepen on soil-plant relationship knowledge under tropical conditions. cultrop [online]. 2009, vol.30, n.4, pp. 00-00. ISSN 1819-4087.

This work presents an outline to demonstrate the need of creating new paradigmatic bases that allow developing a more productive agriculture, optimizing soil-plant relationships without affecting the environmental health. Therefore, it is necessary to make up the new biological and technical approaches of agricultural sciences with those coming from social sciences. It is concluded that to develop a sustainable agriculture, the social, economic and political demands that enable to create a sustainable society should be taken into account. Current paradigms leading soil-plant relationships assume that agroecosystem restrictions can be removed just by applying different kinds of external inputs; they are concentrated on soil exogenous processes and leave behind the endogenous ones, and do not consider plants as organisms with their own abilities and strategies to grow and survive in close relationship with effective soil biological processes. At present, interrelationships existing with the ecological, socioeconomic and cultural contexts, where productive processes settle down, are not considered, so it is wrongly concluded that the knowledge and technologies can be applied in the same way everywhere. So that to solve the current serious feeding troubles, a qualitative jump represented by paradigmatic changes must be made, that allow to assume new commitments, setting down the interdisciplinary nature and systemic approach on research, education, technological transfer and agricultural practice.
