The Three Humic Fractions

Naturally Derived Bio-Organic Carbon Sources

Humates are composed of three major fractions: fulvic acids, humic acids, and humins. Each of these fractions has some similar and some unique physical and chemical properties that contribute to their effectiveness and complement fertilizer programs. Our products contain all three forms of humic substances, maximizing the product benefits

FULVIC ACIDS
are highly soluble and readily absorbed by leaves, making them well-suited for foliar application. Fulvic acids enhance the absorption of nutrients and the efficiency of plant metabolic reactions.

HUMIC ACIDS
are moderately soluble. They have a high cation exchange capacity (CEC), which helps increase a soil’s nutrient holding capacity. Humic acid molecules chelate many essential nutrients and help stimulate soil microbiology

HUMINS
are the least soluble form of humic substances. They contain high levels of carbon and have large nutrient holding capacity. Humins persist in soils for very long periods of time.

In addition to the three humic fractions, humic products utilizing The Andersons Dispersing Granule (DG) Technology contain a unique and powerful ingredient we call humic acid precursor. HUMIC ACID PRECURSOR contains a soluble form of organic carbon that releases into the soil as DG granules disperse. Through biochemical reactions, it is transformed into humic and fulvic acids, enhancing nutrient uptake and improving soil health.

Soluble Granule (SG) Technology

Designed for liquid application, Soluble Granule (SG) Technology creates a highly concentrated dry humic acid granule that completely solubilizes in a liquid solution.

The Andersons soluble granules are clean, uniform and dust free, making them easy to handle. 

Soluble granules eliminate the need to ship water, which reduces handling, storage and freight costs.

Soluble granules are ideal for use in a wide variety of application equipment including sprayers, injectors, drip irrigation tank mixes and other liquid applicators used in turf.

Humic DG CharX harnesses the power of humic acid and biochar in a 50/50 blend, providing the benefits of the more quickly-available humic acid and the long-term soil building qualities of biochar.

Powered by Dispersing Granule (DG) Technology, Humic DG CharX takes soil health to the next level.
 

WHY BIOCHAR?

Having a soil that is high in organic matter has a wide range of benefits for a turfgrass manager. Soil organic matter provides nutrient holding capacity, water holding capacity, and stable aggregates to the soil. Some of the most fertile soils in the world are located in the Amazon region. In this region, these fertile soils, known as ‘Terra Preta’, were created by Amazonian inhabitants via the addition of a variety of organic soil amendments including biochar. Biochar is the result of burning wood byproducts (feedstock) at high temperatures with little to no oxygen present. The resulting byproducts (biochar) are high in carbon and provide excellent physical structures for microbial development. Biochar works to build soil profiles, lasting for hundreds of years. Biochar also contains karrikins, a family of bioactive compounds that stimulate roots to boost new seedlings.

WHAT SETS HUMIC DG CHARX APART?

For peak effectiveness, biochar needs to migrate through the turf and down into the root system. This can be tricky with many products, which bring application difficulties and poor efficacy. While crumbled or micronized biochar products move well through the turf canopy, they do present challenges in allowing the product to properly flow through a standard broadcast spreader. Other biochar products contain larger chunks, which causes the product to remain in the thatch layer on top of the soil for long periods of time. Humic DG CharX features DG Technology, which allows each spherical, low-dust granule to disperse into smaller microparticles when watered. This helps both the humic acid and biochar to move quickly through the turf canopy and down to the root zone, where they can begin to go to work.

SPRAYABLE & SPREADABLE

HCU granules are multipurpose soluble granules that can be solubilized for spray application or dry applied through typical dry spreading equipment. HCU 44-0-0 granules are well suited for use on large turf applications such as golf course tees, aprons, fairways and roughs, sports fields, commercial and residential lawns, ornamentals, and specialty crops.

PROVEN PERFORMANCE

HCU granules provide turf quality and color that is comparable to current industry leading products. In a study conducted on Bermudagrass at the University of Arkansas, HCU granules were applied at a rate of 49 kg N/ha and compared to NutriSphere-N®, UMaxx®, and UFlexx® applied at the same rate. The Bermudagrass plots treated with HCU granules had turf quality and color statistically similar or greater than industry leading products for the 11 week duration of the study. Similar results were observed on Kentucky bluegrass at Penn State University.

COMPATIBILITY

HCU granules are compatible with the most widely used control products for finely maintained cool and warm season turf. For peak product performance we recommend only tank mixing HCU with chelated iron (Fe) micronutrients such as Iron EDTA, HEDTA, etc. Mixing HCU with iron sulfate may potentially cause interaction issues within the tank mix. As always, we recommend a jar test prior to product mixing and application.

Utilizing proprietary technology to produce clean, spherical, free-flowing granules bonded with potassium humate, HCAS (20-0-0-23S) is a versatile fertility product that can be used in many turfgrass, nursery, ornamental, or specialty crops applications.

• Provides an ideal nitrogen source for the cooler months of the growing season
• Complementary to HCU or PCHCU applications in the warmer months of the growing season

Available in two formulations:

• Large particle, spreadable granules for broadcast applications
• Small particle, soluble granules for foliar applications
