Corrección de la acidez del suelo: alteraciones químicas del suelo

Abstract

La alternativa más común para corregir la acidez del suelo consiste en el empleo de enmiendas calcáreas. El objetivo de esta investigación fue determinar el efecto del encalamiento en la fertilidad de algunos suelos representativos de la zona cafetera de Colombia. Se evaluaron las propiedades químicas de cinco suelos luego de un mes de incubación con cinco dosis de cal (0; 1,25; 2,50; 5,00 y 10,00 g dm-3). Los tratamientos afectaron diferencialmente a los suelos en su pH, Ca2+, Mg2+, CIC, Al3+, Fe2+, Mn2+, NO3-, saturación de bases y relación de bases intercambiables. El pH del suelo logró explicar con mayor ajuste las variaciones de Al3+ que el porcentaje de saturación de Al3+. La CIC, determinada mediante el acetato de amonio 1 M y con pH=7,0, no fue un método adecuado para determinar el efecto del encalamiento; caso contrario ocurrió con la solución no-tamponada de cloruro de bario. Se presentó una alta correlación entre el porcentaje de saturación de bases y el pH para cada suelo; sin embargo, no se encontró una tendencia que pudiera explicar las variaciones de todos los suelos de manera conjunta. Los cambios de la CIC, generados por el incremento del pH que ocasionó el encalamiento, estuvieron en función de los contenidos de la materia orgánica. Una parte de los contenidos de Ca y Mg determinados en el análisis del suelo correspondió a la fracción no intercambiable, resultado que se relacionó con la baja solubilidad de la cal y soporta su efecto residual.
