As an artificial fruit crop fertilizer in commercial orange farming, nitrogen, phosphorus, and potassium are the three main plant nutrients required for plant development. In addition to these essential nutrients, other micronutrients such as copper, zinc, boron, and manganese are also necessary in smaller amounts.
Fertilizer needs and applications are determined by soil types, age of trees, and previous soil management practices. In general, a planned fertilization approach should aim to maintain the appropriate balance of essential nutrients in the soil in orange farming.
To avoid overfertilization, it is recommended that growers conduct soil analysis at regular intervals (every 2-3 years) before fertilizing their orange crops.
Nitrogen is the most crucial element in any fertilizer program as it supports the healthy growth of orange trees and enables them to produce delicious oranges. Nitrogen should be applied in three doses over the course of a year. The initial nitrogen fertilizer application should be made in the spring, with two additional applications applied in June and September.
In addition to nitrogen, fertilizers containing phosphorus and potassium should be used judiciously in accordance with soil test recommendations. Phosphorus is essential for the growth and development of roots, stems, and flower buds, while potassium promotes the growth of larger fruit and improved fruit quality.
For young orange trees, an application of 0.5 lbs of NPK (10-10-10) should be used for the first year, 1.0 lbs of NPK (10-10-10) or 4 lbs of 21-0-0 should be applied in the second year, and 2.0 lbs of NPK (10-10-10) should be applied when the plant reaches its 3rd year.
In conclusion, the recommended fertilization schedule for orange crops should be based on the soil test and the orchard’s specific needs. This fertilization schedule for orange trees should be adjusted according to the tree age, soil condition, and nutrient requirements, ensuring that the trees receive all the essential nutrients needed for healthy growth and fruit production.
