Fertilization is one of the key measures to obtain high yields from cultivated coffee. According to the information: for every 1 kg of dried beans harvested, the coffee tree must absorb 70 g of nitrogen (equivalent to 600 g of ammonium sulfate) and 14 g of phosphorus (equivalent to 110 grams of calcium phosphate), 76 grams of potassium absorption (equivalent to 200 to 300 grams of potassium chloride).

① After planting, apply fertilizer in combination with plastic surgery.

The young coffee tree fertilizes mainly with nitrogen fertilizer, at the same time appropriate application of phosphorus and potassium fertilizer. Human and animal manure and green leaf manure also have a good effect on the growth of young coffee trees. Coffee seedlings can be fertilized for the first time two months after planting, and fertilized every 1-2 months thereafter. If applied to human and animal excrement, it should be cooked and diluted and diluted with water at a ratio of 1: 3. Use 5 kg per plant. The water and fertilizer are best applied in the dry season. Ammonium sulfate can be added to the fertilizer and applied together. 150-300 grams of ammonium sulfate. Chemical fertilizers (nitrogen, potassium) can also be dug in shallow trenches 15 cm outside the canopy after rain, each plant applying 15 to 25 grams, the fertilization of young coffee should master the principle of diligent thin application.

② Fertilize coffee trees during fruiting period.

Under good management, the results began in the third year after coffee establishment. The fertilization of adult coffee fruit trees should be based on nitrogen and potassium fertilizers, and should be combined with phosphorus fertilizers and other elements. The effect of applying potassium fertilizer from July to August is the best. As a result, the tree is generally fertilized 5 times a year, respectively in February to March (flowering period), April to May (young fruit period), July to September (fruit start filling period), October to November and December to the following year Fertilize once each month. The annual application of organic fertilizer or compost is 15-20 kg, urea 250-500 g, superphosphate 150-500 g, superphosphate 150-250 g, and potassium chloride 150-200 g.

Coffee special fertilizer

Balance potassium sulfate such as: spraying 14-16-15, 15-15-15. Ammonia potassium sulfate: 17-17-17
