dc.descriptionIn Colombia, cacao farms are located mainly in areas with edaphoclimatic limitations. The predominant soil fertility characteristics from small cacao farms in 13 provinces were evaluated. A total of 635 soil samples (0-20 cm) were taken between 2011 and 2013 from the main cacao producer regions in Colombia. The number of samples was assigned based on the regional cacao production. The resulting data were analyzed with a linear regression model using pH as the dependent variable and soil chemical and physical parameters as the independent variables. Soil texture ranged between 14 and 40% clay, and 31 and 65% sand. Bulk density ranged between 1.07 and 1.28 Mg m-3 with a calculated porosity between 48.8 and 55.0%. There was no evidence of soil compaction. The national pH ranged between 3.9 and 7.9 and was negatively correlated with Al+3 content (R2 = 0.68) and Al saturation (R2 = 0.80) and redicts Al saturation in the range of available Al up to pH >5.2-5.5. In this range, available P (as P2O5) was lower than 12 mg kg-1 and was accepted as a minimum value for a sustainable production. With 4.0 cmolc kg-1 of Ca and 60% saturation of the effective cation exchange capacity (ECEC). A minimum ECEC is proposed at 6.0 cmolc kg-1. A reference table for soils in Colombia is proposed as a guide for the establishment and management of productive and sustainable plantations.
