The rural segments are going through intense changes in their scenarios. Brazilian agriculture and cattle raising sectors, due to exports and production growth for the domestic market, contribute to job growth. However, due to technological changes and advancement of the urbanization, a change in the dynamics of labor in this sector has occurred, modifying their internal relations of production. In this context of changes, this paper analyzes the quality of employment in Brazilian agriculture in the years 1990-2010. Using data from the Relação Anual de Informações Sociais, from Ministry of Labor and Employment, the Formal Employment Quality Index was estimated in the agriculture sector in the period 1990-2010. Results demonstrate an advance in education, wage contraction and high standards of turnover, indicating replacement of labor in this segment.
