Photo by A. Salamanca-Jiménez. 2017. Abstract Colombian coffee crops are mostly grown in mountainous areas that are susceptible to soil moisture luctuations and soil acidity, and are subjected to the effects of climate change. The interactions between nutrients and water availability are complicated and critical determinants of coffee productivity, and hence, designing and implementing appropriate crop nutrition management represents signi icant challenges. The coffee crop cycle at Colombian plantations is very short; an early and full realization of the yield potential is essential and may be accomplished through suitable nutrition approaches. In terms of fertilization, research has mainly focused on nitrogen, and current recommendations indicate that nutrients should be applied differently during each developmental stage. Compared to the reproductive stage, fewer studies have addressed the nutrition requirements during the seedling and vegetative stages of Colombian coffee. The present review aims to describe the special case of coffee nutrient requirements in Colombia, and to suggest principles and alternative respective practices of appropriate fertilization management.
