The use of Clean Fertilizer Technology, particularly CF-N28 and NSB, in sugar beet cultivation is a promising agronomic strategy to improve plant vigor, root yield, and sugar content. Clean Fertilizer technology represents an opportunity to comply with environmental constraints linked to the carbon impact of nitrogen fertilization in general.
This summary presents the results of trials conducted with the support of the agronomy department of Tienen refinery (RT-Belgium, Südzucker) with geometric weighing and sugar analysis between 2019 and 2025 in the loamy region of Belgium, highlighting the agronomical, economical, and physiological benefits of this technology.
The trials were conducted on deep loamy soils with a pH between 6.5 and 7.1, and a standard planting density of 100,000 to 110,000 plants/ha. The baseline fertilization consisted in a moderate supply of nitrogen (NA27). The elements Phosphorus (P) and potassium (K) were applied based on the plant's needs defined by an accredited laboratory. The objective was to evaluate the impact of CF-N28 and NSB applied as foliar sprays at different growth stages of sugar beet.
Control: baseline fertilization with NA27 only.
CF N28 or CF NSB: application of CF-N28 at 25 to 30 L/ha at row closure and/or in combination with a fungicide to evaluate yield and physiological differences.
