Low impact practices are emerging in the aim of reconciling production and environmental objectives. In French Guiana slash and burn practices are still used to increase agricultural area, and lead to a large loss of carbon. A field survey was carried out in order to understand the place of soil in farmers' choices, and to obtain a description of production systems and practices, focusing on identifying those with low impact on carbon dynamics. This step was realized through specific soil carbon stock measurements. Our results show that the "soil object" is mastered by farmers in terms of physical properties, and organic matter is a recognized indicator which is used to inform spatial management of farming systems. Farmers mobilizing low-impact practices have efficient production systems for their economic and environmental benefits. specialized agricultural system Amazonia small tropical agriculture GUYANE FRANCAISE AMAZONIE 068 076 29 21 [9 ] 2020 1166-7699 https://www.documentation.ird.fr/hor/fdi:010079513 10.1051/cagri/2020019 1166-7699 [F B010079513] https://www.documentation.ird.fr/hor/fdi:010079513 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-09/010079513.pdf IRD - Base Horizon / Pleins textes 2020-10-09 2025-02-24 fdi:010079513 fre
