To this end, structured questionnaires were applied to students of the course mentioned on this campus. Subsequently, the responses were analyzed and categorized into six groups: Artificial supply of soil needs; Fertilizer use without technical criteria; Health harmful fertilizers; Environmentally aggressive fertilizers; Beneficial organic fertilization to the soil; Sustainable Emphasis. Most respondents believed that chemical fertilizers are used for soil correction and nutrition, bringing benefits to production, but can cause disease and environmental problems, especially in large quantities.
