Introduction: the amount of fertilizer needed for banana

The amount of fertilizer applied to banana is closely related to soil fertility, climate characteristics, fertilizer properties, fertilization methods, varieties, growth period and planting density. A good harvest can be achieved with fertile soil and less fertilizer. For example, banana plantations in some mountainous areas of Hainan Island have a yield of 30kg per plant without fertilization. Large rainfall, high dry, high yield varieties, high planting density, fertilizer application should be more. Extra-root topdressing is more fertilizer-saving, and hole application and leaching are more fertilizer-saving than sprinkling. Fertilizer irrigation, which is popular abroad, is a more fertilizer-saving fertilization method. Perhaps due to the relationship between fertilization methods and more rainfall, the amount of fertilizer applied to bananas in China is generally much higher than that in foreign countries. The annual application rates of nitrogen fertilizer, phosphorus fertilizer and potash fertilizer per hectare in high-yield banana plantation are 900kg-1200 kg, 270kg-360kg and 1200-1500 kg, respectively. Dry land and mountainous areas with acidic soil can apply 2000 kg of hydrated lime per hectare every year. The inland sloping banana plantation can apply 100-150 kg magnesium fertilizer per hectare per year. Click to get more banana planting techniques click to get more fruit planting techniques
