Applying Fulvic Acid and Fish Protein on Tomato

Numerous biostimulants such as humic acid, amino acid, alginic acid, chitosan oligosaccharide, fish protein, and so on which can promote crop growth, improve quality and yield have been released in the last several years.

Fulvic acid can be absorbed by crops easily because it is a component of humic acid with a smaller molecular weight and higher activity.

Fulvic acid is widely used in agriculture, it not only has the functions of improving soil structure, improving fertilizer utilization rate, enhancing crop resistance, promoting crop growth, and improving crop quality, but also the mineral source potassium fulvic acid has been widely recognized for its effects of promoting root stress resistance, improving quality, and increasing yield.

Fish protein-- a new type of biostimulant, which has a significant effect on improving crop quality and has become a new hotspot in the field of modern agriculture.

In this trial, we will explore how to improve the quality and yield of tomatoes by combining mineral-sourced potassium fulvic acid with fish protein.

Test Products: Fulvic Acid & Fish Protein Biostimulants

Both potassium fulvate and fish protein have a good effect on tomatoes' growth and development. The combination of the two products has a better effect and the best is 20% potassium fulvic acid + 50% fish protein.

Effect on Quality of Tomato

As for the soluble solids, sugar content, and Vc content of tomato, 20% potassium fulvic acid + 50% fish protein has a better effect, and this group has the highest protein content.

For 20% potassium fulvic acid + 50% fish protein, the thickness of the stem and the weight of a single fruit got the most increase with 19.07% and 25.62%. And the increase in production was also the largest at 8.2%.

From the aspect of soluble solids, sugar-acid ratio, and Vc content, there are obvious differences with other groups that the quality and taste of tomatoes in this group significantly improvement. It demonstrates that fish protein has an excellent effect on crop quality improvement.
