Excellent Results in Field Trials

Nutrient Content Increased, Hardness Up 5.7%, Yield Up 10.6%

Gurye-gun, Jeollanam-do announced that as part of the carbon-neutral soil revitalization project at the Gurye-gun Agricultural Technology Center, a demonstration test applying functional kelp liquid fertilizer to greenhouse vegetables (cucumber, zucchini) showed an increase in the content of key nutrients such as potassium, magnesium, and manganese, a 5.7% increase in hardness indicating firmer flesh, and a 10.6% increase in yield.

From October last year to March this year, the county conducted a demonstration test dividing treatment groups with functional kelp liquid fertilizer applied via root irrigation and foliar spraying and untreated groups at 10 cucumber and zucchini farms in the area and the smart farm testbed of the Gurye-gun Agricultural Technology Center.

In particular, root irrigation, which involves directly injecting the diluted functional kelp liquid fertilizer into the soil near the roots using drip hoses, was found to be more effective than foliar spraying, which applies the fertilizer directly onto the crop leaves.

Since general liquid fertilizers or functional liquid fertilizers are continuously used during the cultivation period of greenhouse vegetables, kelp liquid fertilizer is expected to contribute to increasing farm income. Recently, the domestic distribution volume of functional liquid fertilizers containing kelp has also been on the rise.

Park Geun-gyu, director of the Gurye-gun Agricultural Technology Center, stated, “We will continue to promote the distribution of the functional kelp liquid fertilizer, which showed excellent effects in this demonstration test, to farmers.”
