施肥可促进咖啡的生长、开花、结果和改善咖啡质量。常用的氮肥有硫硝酸铵(ASN)、硝酸铵钙(CAN)、硫酸铵(AS)和尿素,使用条件或施用取决于土壤酸碱度(pH值)和当季估计产量。常用的磷肥是单料过磷酸钙(SSP)、磷酸氢二铵(DAP)、双料或三料过磷酸钙(DSP或TSP)。施用钾肥要考虑钾与其他阳离子的比例,施用钙镁肥要根据土壤pH值和过量交接性酸度(Hp)和钾、钙、镁之间的比例,施用复合肥比分别施单一肥料更经济,复合肥料中氮、磷、钾的比例是1:1:1,在咖啡盛花期以前大约6个月时施用。每公顷叶施5—10升(0.5—1%的溶液重量体积)的粒状氮、磷、钾肥可以增加咖啡产量。
Fertilizing can promote coffee growth, flowering, fruiting and improving coffee quality. Commonly used nitrogen fertilizers are ammonium nitrate (ASN), calcium ammonium nitrate (CAN), ammonium sulfate (AS) and urea. Conditions of use or application depend on soil pH (pH) and seasonally estimated production. Commonly used phosphatic fertilizer is single superphosphate (SSP), diammonium phosphate (DAP), double or triple superphosphate (DSP or TSP). Application of potassium fertilizer to consider the ratio of potassium and other cations, the application of calcium and magnesium fertilizer according to the soil pH and excess exchangeable acidity (Hp) and potassium, calcium, magnesium ratio between the application of compound fertilizer than the single fertilizer were more economical, The ratio of nitrogen, phosphorus and potassium in compound fertilizers is 1: 1: 1, which is applied about six months before the flowering period of coffee. Applying 5-10 liters (0.5-1% solution weight by volume) per hectare of granular nitrogen, phosphorus and potassium fertilizers can increase coffee production.
