The province of Manabi is one of the main farming areas of Ecuador, and it has seen an increase in land use in response to the demand for food. Unfortunately, this area growth has brought problems such as inadequate field planting techniques and forest destruction. Alternative techniques or processes to improve productivity in the medium and long term should be the guidance for farmers. Soil conservation practices using mechanized tillage, or conservation tillage (CT), could be an effective option. The objective of this research was to determine areas suitable for mechanized conservation tillage using the method of multi-criteria evaluation (ME).\ A group of specialists from the area, previously selected by area of expertise, appraised land use based on physical characteristics observed through geographic information system (GIS). \Following the appraisal of different maps, various levels of adequacy were found, and a final zoning map for mechanized conservation tillage was created. Multi-criteria evaluation showed that Manabi province has 8.68% of total area at the suitable level for mechanized conservation tillage when using crop rotation
