Growing Coffee in Colombia
Even though it’s been 4,000 years, the soil resulting from the last major eruption of Tolima is still considered “young soil,” filled with nutrients that are no longer found at the same levels in old soil. There is a long list of elements on offer in volcanic soil that are fading or absent in other soils, such as high levels of potassium and nitrogen. Also present is something called “Boron,” which arrived from outer space a long time ago, and is important to cell walls, the creation of enzymes, and the production of flowers and fruit, meaning Boron contributes to yield. Beyond the nutrients, the structure of volcanic soil is also beneficial to coffee growing. It can soak up and hold moisture while, at the same time, facilitate good drainage so water doesn’t pool, which is not good for coffee plant roots. Coffee plants like to take a drink, then take a break. Also, volcanic soils are usually found on an incline, which also helps with drainage.
