Résumé:
A family farm with agroecological base, has spurred significant changes in the lives
of farming families, either in soil management in relation to the environment, eating
habits, food security, or even productive autonomy. In this perspective, assessing soil
quality within systems (for conventional agroecological) agroecological transition may
provide better understanding of the effects of this system of cultivation. In search of
the sustainability of agricultural systems, using indicators in the monitoring of soil
conditions constitutes an important tool for decision making in the conduct of
productions. The objective of this study was to compare physical, chemical,
biochemical, microbiological and thermogravimetric soils of the rough mesoregions of
Paraíba in agroecological transition properties. This study was developed in Meso -
Heath of the Wasteland Paraíba. Soil samples were collected on properties of
farmers in agro-ecological and conventional cropping system, which were subjected
to different indicators of soil sustainability. Chemical indicators nitrogen, light organic
matter, total organic carbon and organic matter showed higher correlation and
sensitivity as the use of soil quality indicators in agro-ecological transition.
Thermogravimetry showed potential in the identification of soils in relation to organic
matter content of agricultural soil.
