Abstract
Percolación y lixiviación de nutrimentos en suelos bananeros al este del río Reventazón, Costa Rica. El objetivo de este trabajo fue determinar la pérdida por lixiviación de Ca, Mg, K y nitrógeno nítrico en suelos bananeros. Entre el 2003-2004 en la Finca Venecia, situada en Matina de Limón, Costa Rica, se emplearon tres fuentes de fertilizante nitrogenadas: urea (U), nitrato de amonio (NA) y sulfato de amonio (SA). Se muestreó a una profundidad de 60 cm utilizando lisímetros, y el volumen del agua percolada (D) se calculó mediante el método indirecto del balance hídrico del suelo (BHs). En pH, independientemente de las fechas de muestreo, no se determinaron diferencias estadísticas. La concentración de calcio (Ca) en los lixiviados para los diferentes tratamientos durante las diferentes épocas de muestreos no fue significativa, pero se presentaron diferencias entre el tratamiento con urea con respecto a los tratamientos de NA y el SA, sin embargo, no se encontraron diferencias entre el NA y SA; tampoco entre los promedios de las concentraciones de magnesio (Mg) y el potasio (K) en los lixiviados. Para el nitrógeno nítrico, sólo hubo diferencias significativas entre el NA respecto a la U y al SA, tanto en forma general, como entre fechas de muestreo.
Percolation and leaching of nutrients in banana soils to the East of the Reventazón river, Limón, Costa Rica. The objective of this study was to detwermine leaching losses of Ca, Mg, K and nitric N in banana soils. The work was conducted between 2003-2004 in the Venecia Farm in Matina, Limón, Costa Rica. Three nitrogen fertilizer sources were used: urea (U), ammonium nitrate (aN) and ammonium sulfate (HS). Sampling was conducted at a depth of 60 cm using lysimeters and the volume of percolated water (D) was calculated using the indirect method of soil water balance (BHs). Irrespective of the sampling dates no statistical differences were determined found for pH. The concentration of calcium (Ca) in the leachate for different treatments during different times of sampling, was not significant, but significant differences were found between treatment with U with respect to treatment of NA and SA. No differences between the NA and SA or in the average concentrations of magnesium (Mg) and potassium (K) in the leachate were observed. In the case of nitric nitrogen, significant differences were detected only between the NA regarding the U and SA, both in general and between sampling dates.
