Retention of phosphorus in the soil solid phase is a complex process, caused by a combination of physical and chemical mechanisms that determine pools of compounds with different degrees of solubility. The amount of P available in a given pool can be associated with the adsorption maximum proposed by the Langmuir isotherm model, and with the energy with which it is retained. The aims of this work were: i) to evaluate the impact of the fertilization history and soil type on phosphorus adsorption parameters, and ii) to analyze the effect of soil properties, mainly the phosphorus adsorption parameters, on the yield of wheat, soybean and corn crops. In this study we established that the Bray & Kurtz 1 extractant is insufficiently sensitive for assessing changes in the nutrient availability when phosphorous concentrations are relatively low.The amount of phosphorus retained in the labile pool and its retention energy, however, are sensitive indicators of the availability of this nutrient. These indexes explain most of the variations in crop yields, and are determined more by P fertilization management than by soil type La retención de fósforo en la fase sólida del suelo es un proceso complejo que es causada por una combinación de varios mecanismos físicos y químicos, que determinarán reservorios de compuestos con diferente grado de solubilidad. La cantidad de P disponible en un reservorio dado se puede asociar al máximo de adsorción propuesto por el modelo de isoterma de Langmuir y a la energía con la que está retenida en la fase sólida. Los objetivos de este trabajo fueron: i) evaluar el impacto de la historia de fertilización y el tipo de suelo en los parámetros de adsorción de fósforo, y ii) analizar el efecto de las propiedades del suelo, principalmente los parámetros de adsorción de fósforo, en el rendimiento de los cultivos de trigo, soja y maíz. En este estudio se estableció la baja sensibilidad del extractante Bray y Kurtz 1 para evaluar los cambios en la disponibilidad de fósforo cuando las concentraciones son relativamente bajas, mientras que la cantidad del nutriente retenido en el reservorio lábil y su energía de adsorción son indicadores sensibles de su disponibilidad. Estos índices explican la mayor parte de las variaciones en los rendimientos de los cultivos y están determinados más por las condiciones de manejo que por el tipo de suelo. publishedVersion Fil: Silva Rossi, Martín María.
