Oil palm is a crop that requires large amounts of nitrogen, phosphorus, potassium and magnesium. In Africa and Southeast Asia, according to the output and analysis results, the average nutrients required for 20 tons of fresh fruit ears are: 56kgN, 22kg P2O5, 105kg K2O.

When planting, sufficient organic base fertilizer and appropriate amount of superphosphate are applied. At young age, oil palm is sensitive to nitrogen fertilizer. As a result, a large amount of phosphorus, potassium fertilizer and appropriate amount of nitrogen fertilizer are required.

There is a large demand for potassium fertilizer in the oil palm flowering period, and the method of supplementing potassium on the page can be used to change the effect of potassium deficiency on zongzi leaves.

More potassium and less magnesium are beneficial to the increase in the number of fruit ears. The use of phosphate fertilizer is generally once a year. Based on the growth characteristics of oil palm, trace elements can be used in the best fertilization period to reduce the occurrence of deficiency.
