Description: The conservation agriculture (CA) needs "no-fire" (no-fire CA) in Brazilian Amazon, where slash-and-burn agriculture (SBA) is still common, which decrease soil organic matter (SOM) and increase greenhouse gases emissions and decrease crops production. Soil tillage to smallholders do not is actually a common practice nowadays. But this scenario is changing by the regional agribusiness. In the Juruá region of Acre State, where this study was carried out, predominate sandy soils. Cassava (Manihot esculeta, Crantz) is the main crop and almost monoculture in smallholder farming. But cultivation of cassava is SBA-based, i.e. a low technological system. Soil tillage associated to soil sandy features and total annual precipitation in Juruá can increase erosion because cassava cultivation starting is coincident to begin of rainfall regional station. This corolarium indicate to a decreasing productivity of cassava and likewise to others agricultural crops. The hypothesis of this study is that no-fire CA to smallholder farming is part of the solution of scenario presented. To test this hypothesis no-fire CA models were evaluated in comparison to SBA. Economic and environmental results are presented.
