By using Haifa's fertilizers, the nutrients uptake curve can show great improvement
Plant population: Stalk density at harvest 90,000-150,000 Stalk/Ha. (achieved by planting 10,000-15,000 cuttings or setts of 2-3 eyes or bud per Ha).
Soil type: Medium to heavy; optimal pH 5.0 - 8.5.
Expected yield: 200-300 MT/ha.
Phosphate - All applied at planting according to soil analysis.
Potassium - In heavy soils, all the recommended amount of K is applied as base dressing. In lighter soils, it is preferable to apply one half of the total amount as base dressing and the rest 6 months later.

SOP = Potassium Sulphate (50% K2O).
Haifa Multi-K™ = Potassium Nitrate (13-0-46)
AN = Ammonium Nitrate (34% N)
MAP = Mono-Ammonium Phosphate (12% N and 61% P2O5)

This treatment should be applied as a series of 3-4 applications, 3-4 weeks apart.
Do not wait with the application of Haifa Bonus™ until you need to apply Glyphosate because the Glyphosate application is about 35 – 40 days before harvesting while the demand for K at this stage is very low.
Highest demand for K in sugar cane is between 4 – 2,5 months before harvest.
Haifa Bonus application should be done at the best phenological stage, by 1-2 applications with 10% concentration (3Kg/30liters/hectare) by plane. Aerial
