Gascoyne, North Dakota. Leonardite is a
mined mineraloid that formed as deposits
of ancient plant material aged and oxidized
over time. Low in contaminants and high in
organic content, North Dakota Leonardite
contains significantly more humic and fulvic
acids than other sources.

HUMIC ACID
DOUBLE BLACK is a concentrated aqueous mixture of Humic Acid that
is suitable for soil (broadcast, band, drip) and foliar application. It can
be used alone or mixed with a wide range of plant protection and plant
nutrition products. Its naturally acidic pH enables growers to also use
it with acidic fertilizers or to reduce the pH in alkaline tank solutions.
Double Black Tank Mix Compatibility
Unlike extracted humic products, DOUBLE BLACK is compatible
with liquid fertilizer.

Both mixtures were agitated for two minutes.
DOUBLE BLACK is a mixture of long chain
phenol molecules, naturally found
in the best of top soils. DOUBLE BLACK
improves the health of the soil making
nutrients more available to the crop.

Soybean Application Guideline
Recommended rate =
2 quart/acre (broadcast spray)
(lower rates in-furrow)
Timing is from emergence up to R1 growth
stage (R1 is when soybeans start flowering)
Can be sprayed broadcast alone with post
emergence herbicides, fertilizers, or with fungicides
Soybeans treated with DOUBLE BLACK yielded about 10% more
harvestable soybeans per acre
Soybeans treated with DOUBLE BLACK yielded 5.1 and 5.6 more
bushels per acre than the untreated check
Soybeans treated with DOUBLE BLACK grow larger, healthier, and
have more vigor
