Determinación de la concentración de gases provenientes de suelos agrícolas fertilizados con productos inorgánicos bajo condiciones controladas en laboratorio

Abstract

Abstract: This research determined the concentration of CO₂ emitted by agricultural soils fertilized and sterilized using an autoclave with inorganic products under controlled laboratory conditions. The effect of fertilizer type (granular, liquid, and powder) and dosage (low, medium, and high) on pure chemical emissions was evaluated. The results showed that powdered fertilizer generated the highest maximum emissions (267 ppm), followed by liquid inorganic fertilizer and urea, confirming that the physical form influences chemical reactivity. A two-phase emission pattern was also identified, with main peaks at 48 hours. The dose-response relationship was not linear, showing chemical saturation effects at high doses. This work provides crucial quantitative evidence for optimizing fertilization practices toward more sustainable agriculture.
