L-CBF BOOST™ 4-0-3-2S

Soil Nutrition Solutions - Liquid Carbon-Based Fertilizer

QLF Agronomy's L-CBF BOOST™ 4-0-3-2S is a liquid carbon-based fertilizer that combines balanced crop nutrients with complex carbon sources to enhance soil biology and improve nutrient availability.

Key Benefits

Boost Soil Health

Contains 30% sugars and fermentation yeast extract to increase soil microbes, improving nutrient availability, soil structure, and residue decomposition.

Reduce Leaf and Root Stress

When added to UAN, L-CBF BOOST™ helps reduce potential stress caused by high-nitrogen applications.

Reduce Drift Losses

Adding L-CBF BOOST™ to liquids and sprays minimizes losses to drift and enhances performance.

Versatile Application

L-CBF BOOST™ mixes easily with most liquid fertilizers; always perform a jar test before use to ensure proper blending.

Application Guidelines

Combine L-CBF BOOST™ with other liquids at a 10-20% inclusion rate (e.g. corn, wheat, grasses). Refer to soil test and your consultant for specific uses.

Michigan soybean field observation

BOOST-treated plants averaged 2.2× the Brix of the untreated check

At the R3 growth stage, leaf-sap readings from BOOST-treated soybeans averaged 14.9 Brix across three sampling dates. Untreated plants averaged 6.8 Brix under the same midday, full-sun sampling conditions.

Untreated check6.8 Brix
BOOST treated14.9 Brix

+8.1 Brix · 120% treated advantage

Higher Brix can indicate greater soluble-solids production and energy availability. It is a comparative field indicator—not a stand-alone yield predictor or performance guarantee. Less insect leaf feeding was observed on treated plants, but the observation does not prove pest control or cause and effect.
