Coffee manuring

Abstract

Reports on the results obtained on some farms where manure was applied to the trees, consisting of 20 pounds of nitrogen, 30 pounds of phosphoric acid and 40 pounds of potassium per acre. Experiments on the manuring of coffee, indicate that it is good to apply 40 pounds of nitrogen per acre, without corresponding amounts of phosphoric acid and potassium. The balanced fertilization effects are manifested in the vegetative vigor of the plant. So far no one knows what are the requirements for payment of the coffee, needing to analyze data for many years on: soils, climate, treatments, and old varieties of plants, to reach a definitive conclusion.
