Evaluation of phosphorus adsorption in a sandy-loam soil in Perugorria, Corrientes

The study analyzes phosphorus adsorption in a sandy loam soil in the town of Perugorría, located in the southern part of the province of Corrientes, in the fifth section of the department of Curuzú Cuatiá. Samples were taken at a depth of 20 cm and characterized through physicochemical analyses. Pho...

Samples were taken at a depth of 20 cm and characterized through physicochemical analyses. Phosphorus adsorption was evaluated at different concentrations and temperatures (5, 30, and 45 °C). The results showed low adsorption, with values ranging between 17.81% and 26.19%. This indicates that a significant portion of phosphorus remains in solution, increasing the risk of leaching and runoff. Adsorption was found to be favored by higher temperatures, leading to an increase in distribution constants (KD) and the organic partition coefficient (KO.C.). This suggests a greater interaction with soil organic matter. The adsorption isotherm analysis showed that the Langmuir model fits better than the Freundlich model, indicating that adsorption occurs at specific sites rather than in multiple layers. The thermodynamic parameters revealed that the process is spontaneous and endothermic, with an increase in entropy. This suggests that phosphorus mobility is enhanced at higher temperatures. It is concluded that due to the soil's low adsorption capacity, improving fertilization management is crucial to minimizing losses by leaching and maximizing phosphorus availability for plants. This optimization will enhance crop productivity and promote agricultural soil sustainability. El estudio analiza la adsorción de fósforo en un suelo franco arenoso de la localidad de Perugorría ubicada al sur de la provincia de Corrientes, en la quinta sección del departamento de Curuzú Cuatiá. Se tomaron muestras a 20 cm de profundidad y se caracterizaron mediante análisis fisicoquímicos, evaluando la adsorción del fósforo a distintas concentraciones y temperaturas (5, 30 y 45 °C). Los resultados mostraron una adsorción baja, con valores entre 17,81 % y 26,19 %, lo que indica que gran parte del fósforo permanece en solución, aumentando el riesgo de lixiviación y lavado por escorrentía. Se encontró que la adsorción es favorecida por temperaturas más altas, con un incremento en las constantes de distribución (KD) y el coeficiente de partición orgánica (KO.C.), lo que sugiere una mayor interacción con la materia orgánica del suelo. El análisis de isotermas de adsorción mostró que el modelo de Langmuir se ajusta mejor que el de Freundlich indicando que la adsorción ocurre en sitios específicos y no en múltiples capas. Los parámetros termodinámicos revelaron que el proceso es espontáneo y endotérmico, con un aumento de la entropía, lo que sugiere que la movilidad del fósforo se ve favorecida a mayor temperatura. Se concluye que, debido a la baja capacidad de adsorción del suelo, es crucial mejorar el manejo de la fertilización para minimizar pérdidas por lixiviación y maximizar la disponibilidad de fósforo para las plantas, optimizando su uso en la productividad de cultivos y promoviendo la sostenibilidad del suelo agrícola.
