RETENTION OF PHOSPHORUS IN SOILS DEDICATED TO MAIZE CULTIVATION IN AZUERO REGION
The objective of this research was to estimate the equivalent fertilizer dose to apply on soils dedicated to maize crop, in order to reach the optimum phosphorus concentration for this crop, in alfisol and inceptisol soils of the Azuero region. Soil samples were taken from eight localities in the corn region of Los Santos province. To each sample, a complete physical-chemical characterization was made and the Langmuir isotherm was also generated. The maximum adsorption capacity of each soil sample was calculated to retain phosphates (amount), soluble phosphates in the soil solution (intensity), and the property of a soil to resist changes in the concentration of phosphorus in solution or energy of retention (capacity). Inceptisol soil of Guararé locality, adsorbed the highest amount of phosphorus with 943,1 mg.kg-1 followed by Pedasi alfisol and San José inceptisol, with values of 794,7 and 788,3 mg.kg-1, respectively. Inceptisol soils from Guararé and San José localities, as well as alfisols from El Ejido and Pedasí, showed higher levels of retention energy with values of 1,85; 1,75; 0,59 and 0,46; respectively. For maize crop, the equivalent dose to reach optimum phosphorus concentration in soils was found in Llano Abajo inceptisol soil, being 202,8 kg.ha-1.

El objetivo de esta investigación era estimar la dosis equivalente de fertilizante que se debe aplicar en suelos dedicados al cultivo de maíz para poder alcanzar la concentración de fósforo óptima, en suelos alfisoles e inceptisoles de la región de Azuero. Se tomaron muestras de suelos de ocho localidades de la región maicera de la provincia de Los Santos. A cada muestra, se le realizó una caracterización físico-química completa y además se elaboró la Isoterma de Langmuir. Se calculó la capacidad de adsorción máxima de cada muestra de suelo para retener fosfatos (cantidad), fosfatos solubles en la solución del suelo (intensidad), y la propiedad que posee un suelo para resistir los cambios en la concentración de fósforo en solucióno energía de retención (capacidad). El suelo inceptisol de lalocalidad Guararé, adsorbió la mayor cantidad de fósforo con 943,1 mg.kg-1 seguida por el suelo alfisol de Pedasí y el inceptisol de San José, con valores de 794,7 y 788,3 mg.kg-1, respectivamente. Los suelos inceptisoles de las localidades de Guararé y San José, así como los alfisoles de El Ejido y Pedasí, presentaron mayores niveles de energía de retención con valores de 1,85; 1,75; 0,59 y 0,46; respectivamente. Las dosis equivalentes de fósforo para alcanzar la concentración óptima en el suelo, para el cultivo de maíz, se presentaron en el suelo inceptisol de Llano Abajo, siendo de 202,8 kg P.ha-1.
