pH relationship and nutrient availability for cacao in an Entisol from the Colombian Amazon

Liming is a common practice in acid soil management; however, the information on liming in cacao soils of the Colombian Amazon region is precarious. Incubation curves were built in a highly acid Typic Udorthents cultivated with cacao (Theobroma cacao L. - Malvaceae), for which increasing doses (0 -...

Incubation curves were built in a highly acid Typic Udorthents cultivated with cacao (Theobroma cacao L. - Malvaceae), for which increasing doses (0 - 1 - 3 - 5 - 7 - 9 -11 Mg/ha) of dolomite lime (CaMg(CO3)2) and calcium carbonate (CaCO3) were used, in order to establish the type and amount of liming material (ME) with better reactivity, and the one that is better favored with the acidity changes: pH, Al3+, H+, total acidity. Models to estimate the ME dose needed to manage the soil in order to obtain the desired pH (≥5.5) were generated. Subsequently, the soil was then limed under field conditions and pH, Al3+, Al in solution (Alsol), aluminum saturation (sai), cation exchange capacity (cec) and N, P, K, Ca, Mg, Zn, Cu, B, Fe and Mn availability were evaluated. The results show that the greatest reaction of liming materials in these soils occurs after 60 days; applications of 7 Mg/ha allowed to raise the pH from 5.5 to 6.0 and decreases Al and Fe levels. These changes improved the cec and nutrient availability (Ca, Mg, P, Zn) for cacao without affecting other nutrients such as N and K. El encalado es una práctica común en el manejo de suelos ácidos, sin embargo, la información sobre encalado en suelos cacaoteros de la Amazonia colombiana es precaria. Se construyeron curvas de incubación en un Typic Udorthents fuertemente ácido cultivado con cacao (Theobroma cacao L., Malvaceae), para lo cual se utilizaron dosis crecientes (0 - 1 - 3 - 5 - 7 - 9 - 11 Mg/ha) de cal dolomita (CaMg(CO3)2) y carbonato de calcio (CaCO3), con el fin de conocer el tipo y cantidad de material encalante (ME) de mejor reactividad y el que más favorece los cambios en la acidez: pH, Al3+, H+ y acidez total. Se construyeron los modelos para estimar la dosis de ME necesaria para llevar el suelo al pH deseado (≥5,5). Posteriormente se encaló el suelo en condiciones de campo y se evaluó el efecto en pH, Al3+, Al en solución (Alsol), saturación de aluminio (SAI), capacidad de intercambio catiónico (CIC) y la disponibilidad de N, P, K, Ca, Mg, Zn, Cu, B, Fe y Mn. Los resultados muestran que la mayor reacción de los materiales encalantes en estos suelos se presenta después de 60 días. Aplicaciones de 7 Mg/ha permitieron elevar el pH de 5,5 a 6,0 y disminuir los niveles de Al y Fe, cambios que mejoraron la CIC y la disponibilidad de nutrientes para cacao (Ca, Mg, P, Zn) sin afectar otros nutrientes como N y K. 2019-08-09T19:30:19Z 2019-08-09T19:30:19Z 2017 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistacta.agrosavia.co/index.php/revista/article/view/742 10.21930/rcta.vol18_num3_art:742 http://hdl.handle.net/20.500.12324/35264 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa http://revistacta.agrosavia.co/index.php/revista/article/view/742/492 http://creativecommons.org/licenses/by-nc/4.0 application/pdf Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Ciencia y Tecnología Agropecuaria; Vol 18 No 3 (2017); 529-541 Ciencia y Tecnología Agropecuaria; Vol. 18 Núm. 3 (2017); 529-541 revista Corpoica Ciência e Tecnologia Agropecuária; v. 18 n. 3 (2017); 529-541 2500-5308 0122-8706 10.21930/rcta.vol18-num3
