Orange Tree Fertilizer Requirements

Orange Tree Fertilizer Requirements

How to fertilize citrus trees

 

Orange trees have certain needs in nitrogen, phosphorus, potassium and calcium. Some microelements are also necessary (iron, boron, magnesium, aluminum, manganese, zinc and copper). Lack of nitrogen slowly decreases vegetation and causes yellowing of the foliage of the tree, premature defoliation and decreased production.

We can say that the annual fertilizer requirements of the orange tree are 260 to 440 lbs. (120 to 200 kg) per hectare for N, 67 to 100 lbs. (30 to 45 kg) per hectare for P and 130 to 330 lbs. (60 to 150 kg) per hectare for K. Keep in mind that 1 ton = 1000 kg = 2.200 lbs. and 1 hectare = 2,47 acres = 10.000 square meters.

Under normal conditions, the supply of 260 to 440 lbs. (120-200 kg) nitrogen per hectare can be beneficial (ask a licensed agronomist in your area). Orange farmers often provide 5,5 – 7,7 lbs (2,5-3,5 kg) P2O5 in every adult tree for 4-5 consecutive years. In many cases, they may also add 3,3-6,6 lbs. (1,5-3 kg) K2O in every adult tree for two consecutive years. The best time to apply fertilization is during spring. Application is done by soil or foliar fertilization. Foliar fertilization is a fast an effective method when iron, magnesium, boron and copper deficiencies have to be addressed during critical stages of crop development. The soil pH must also be checked at least once a year. If soil pH is greater than 7, then you may have to take actions in order to correct it through applying an acidifying fertilizer, after consulting a licensed agronomist.

However, these are just some common practices and should not be followed without making your own research. Every field is different and has different needs. It is beneficial to test your soil at least once a year, and take corrective actions after consulting an expert.
