Agronomy students generally lack interest in chemistry. The objective of this work was to modify the analytical chemistry curriculum to increase student interest. Samples of soils and plants prepared by students were introduced. Soil was treated with molasses residue, organic matter (chicken manure and humus obtained from goat excrement), and lime. The response of plants to the different soil treatments increased student interest in chemical analyses. Evaluation of several chemical and physicochemical parameters of samples demonstrated in a clear way the application of the theoretical and practical concepts of chemistry.
