Introduction: Sustainable semidesert agriculture requires integrating scientific knowledge and local experience through soil diagnosis. Objective: To describe university extension based on soil diagnosis as a knowledge exchange strategy with agricultural entrepreneurs for interpreting soil conditions and supporting crop management. Materials and methods: A quantitative, descriptive, non-experimental, and cross-sectional study was conducted between January and March 2026. Tuna and maize soils were evaluated through physicochemical parameters recorded using a CHTR-8IN1-01 multiparameter soil detector. Data were analyzed using descriptive statistics and Student’s t-test. University extension was developed through joint interpretation activities with agricultural entrepreneurs. Results: Soils associated with tuna cultivation showed higher mean values of nitrogen (26.42 mg/kg), phosphorus (37.08 mg/kg), potassium (85.50 mg/kg), moisture (25.46%), and fertility index (295.58 units) compared with maize soils. Soil temperature showed a significant difference between agricultural systems (21.56 °C vs. 19.93 °C; p = 0.0072), whereas pH, electrical conductivity, moisture, macronutrients, and fertility index did not show statistically significant differences. University extension integrated soil information and productive experience through joint interpretation of edaphic conditions, strengthening the understanding of soil behavior and its relationship with crops. Discussion: Physicochemical soil diagnosis enabled a contextualized understanding of edaphic conditions and demonstrated the articulation between academic knowledge and productive expertise through agricultural university extension. Conclusions: University extension based on edaphic evidence strengthened knowledge exchange and supported sustainable agricultural decision-making in semi-desert production systems.
