Fulvic Acid – A Sweet Addition to Growing Sugar Beets

Updated: Apr 20


When it comes to commercial growing, achieving optimal health and growth performance is essential. There have been several research studies done on fulvic acid and sugar beets that support optimal performance.


According to a 2021 study on the influence of fulvic acid on spring cereals and sugar beets seed germination and plant productivity, the conclusions are… well… sweet:

  • The use of fulvic acids for seed dressing reliably increased the final germination percentage and decreased the mean germination time in spring wheat, spring barley, and sugar beet.

  • Fulvic acids increased the length of spring wheat and barley shoots and the air-dry weight of shoots and roots.

  • The use of fulvic acids during plant vegetation reliably increased spring wheat grain yield and sugar beet roots yield, and improved yield quality. Combinations of fulvic acids with pesticides were also investigated.

  • The use of fulvic acids in combination with pesticides used in sugar beet crops improved the action of those pesticides, so it was possible to reduce the rates used, thus reducing environmental pollution.

Published in the International Journal of Current Microbiology and Applied Sciences, an article showed that foliar application statistically improved sucrose, extractable sugar, purity, sugar lost to molasses, extractability percentages and yield (tons/ fed) in both seasons. Fulvic acid surpassed the other humic substances in the content of sucrose, extractable sugar, and purity percentages; also yield, and lowest juice impurities in both seasons.


Also concluded, the application of 72Kg N/fed with fulvic acid helpful for suggesting good use of nitrogen fertilizer along with fulvic acid to increase sugar beet crop yield and improve its quality.


According to Hannan Y Mohamed and Mohamed M.I Afifi from the Sugar Crops Res. Institute in Giza, Egypt in their published article, Response to Some Sugar Beet Varieties to Foliar Application of Boron and Fulvic Acid:

Foliar spray boron 200mg/l with fulvic acid recorded the best root length and dimeter 30.33, 32.33, 12.44 and 10.44cm/plant during two seasons respectively. Maximus variety was the best in root length and diameter 28.83, 30.83, 11.17 and 9.22 cm/plant in both seasons respectively. Also, fulvic acid with boron either 200 or 100mg/l achieved the best significantly result in root and sugar yield (31.39, 32.03, 5.04 and 8.83) ton/fed. respectively in both seasons. The foliar applications fulvic acid with boron (100mg/l) treatment obtained the highest result in sucrose, sugar extraction, purity and extractability percentages on different sugar beet varieties.


A study was also performed on our AGT-50 on the effects on sugar beet biomass which concluded the following

  • AGT-50 amended before sugar beet seeding increased yield from 2.67 to 5.18 metric tons per hectare (depending on fertilizer rates). Fertilizers sprayed on plants during vegetation increased sugar beet yield from 0.74 to 4.00 metric tons per hectare. The greatest sugar beet yield was obtained from the Variant Six group, on which 1.5 liters per hectare AGT-50 were amended before seeding and on which AGT-50 was also sprayed twice (at one liter per hectare) during vegetation.

  • The greatest quantity of white sugar was obtained from the Variant Eight group, on which 2.0 liters per hectare AGT-50 were amended before seeding and on which AGT-50 was also sprayed twice (at one liter per hectare) during vegetation.

  • The maximum income bonus, at 181.56 euros per hectare, was obtained from the Variant Six group, on which 1.5 liters per hectare AGT-50 were amended before seeding and on which AGT-50 was also sprayed twice (at one liter per hectare) during vegetation.

Proven by science, fulvic acid is a sweet addition to sugar beet growing.


To assist with achieving optimal performance, we recommend considering the outstanding results of the above scientific findings. Science has proven again and again that a well-rounded health and growth program can no doubt help reach your desired outputs.
