CITRUS CROP GUIDE OF FIELD MANAGEMENT AND FERTILIZATION
Jul 04, 2016

Growing citrus and getting high yield is a task that requires profound knowledge and expertise. Here are just some of the information for reference :


- Intensive citrus cultivation requires the use of fertilizers, close monitoring and control of pests, diseases and weeds, effective irrigation and control of tree size.

- Citrus can be grown on a wide variety of soils, from sand to loam and clay. Both acidic and alkaline soils are acceptable.

- Citrus trees have shallow root systems. It is important to aim irrigation at the effective root zone, minimizing the amount of water leaching past. For citrus, the effective root zone is usually in the top 30 to 40 cm, depending on the soil type.

- Nitrogen is one of the primary nutrients absorbed by citrus roots, preferably in form of nitrate (NO3-) anion. This nutrient is equally essential for good cell division, growth and respiration.

- Potassium nitrate fertilizer in prilled form can be applied manually or by fertilizer spreader, a source of nitrogen in nitrate (NO3-) form and chlorine free potassium. Prevents salinity injuries and is quickly up-taken by tree roots.

- Foliar fertilizer affects the external and internal fruit quality: increases size and weight, prevents creasing and splitting, improves soluble solids and vitamin C content. In addition, this fertilizer corrects plant nutrient deficiencies quickly and effectively.
