Recommendations on the use of fertilizers for mango

Views: 104    

Compared to other fruit tree species, mango fruit has a greater need for potassium, so special attention should be paid to supplementing potassium fertilizer. It is expected to apply 5 kg of 15-15-15 type compound fertilizer per plant per year, supplemented with 1 kg each of urea and potassium sulfate, and insist on some additional organic fertilizer if possible, the fruit quality development will be good.


The recommended fertilization rate for mango fruiting trees is 0.75 kg of nitrogen fertilizer (containing 28% nitrogen), 0.75 kg of superphosphate and 0.50 kg of potassium chloride per plant per year in the 4th-5th years. In the following years, the fertilization rate was increased by 0.25 kg of nitrogen, phosphate and potassium fertilizers per plant every 2 years. The maximum annual application is 1.50 kg of nitrogen fertilizer, 1.50 kg of superphosphate and 1.25 kg of potassium chloride per plant, i.e. 4.25 kg of total fertilizer per plant per year. China has the habit of attaching importance to the application of agricultural fertilizer, which can be increased by 20-40 kg or even more per plant per year according to the actual situation. Some mango orchards are used to fertilize with compound fertilizer, 4-6 kg of compound fertilizer per plant per year according to the fruit hanging situation. A little light fertilizer during the flowering period will do.
