To improve the efficiency in the use of fertilizers it is necessary to know those characteristics of the soil which have an effect on it. With the purpose of evaluating the effect of the texture of soil on the losses of potassium (K+) by leaching, soil samples at 25 cm deep were taken, using PVC tubes in four cartographical units of soil in the Coffee Zone of Colombia: San Simón (Eutropept, sandy loam), Montenegro (Fulvudands, sandy loam), Chinchiná (Melanudands, loam) and Doscientos (Dystropept, clay loam). Half of the samples from each unit of soil (seven) were superficially fertilized with 4 g of K in the form of KCl (60% of K2O) and the other half weren’t; subsequently, 360mL of distilled water was administered every four days for 25 ti...
