WELCOME Understanding Humic Substances: Benefits of Humic & Fulvic for Turf Management Presented by Ryan Zadow Product Formulation and Technical Sales BioAg, Independence OR Humic Substance Specialists
Brief Nomenclature / Definitions Organic Matter Hummus Humic Substances (RAW) Humic Acid (alkali soluble) Fulvic Acid (soluble across the whole pH range) Humin and Mineral (insoluble)
Brief Properties : Structure / Size Humic: soil conditioning fraction Fulvic: biological fraction
Functions of Humic Substances in Agriculture There is a long list of positive effects that are well described in the scientific literature. Some are direct mechanisms and some indirect.
Functions of Humic Substances for Turf Humic Acid : Soil conditioning fraction of humic substances Forms beneficial aggregates - improves air porosity - increases drainage or holding capacity - adds CEC / nutrient holding capacity - detoxifies soil: Sequesters heavy metals Buffers excess sodium / reduces high E.C. and pH Breaks down pesticide and herbicide residue Pulls apart hydrocarbons (oil & gas)
Functions of Humic Substances for Turf Humic Acid : Soil conditioning fraction of humic substances B. Reduces leaching of nitrogen and extends it’s time in the root zone
Functions of Humic Substances for Turf Humic Acid : Soil conditioning fraction of humic substances • C. Releases bound Phosphorous • direct mechanism • Also through stimulation of beneficial microbes like b. megaterium and mycorrizhae Note: stimulation/balancing of the beneficial microbial biota and humic substance direct mechanisms go hand in hand.
Functions of Humic Substances for Turf Fulvic Acid: biologically stimulating fraction A. Improves root structure and mass, especially adventitious roots.
Functions of Humic Substances for Turf Fulvic Acid: biologically stimulating fraction • B. Stimulates metabolism which leads to: • catalyzes nutrient uptake • increases respiration • - improved rate of cell division
Functions of Humic Substances for Turf Fulvic Acid: biologically stimulating fraction • C. Chelation of micronutrients • prevents precipitation and tie-up • better releasing of micronutrients then “conventionals” like EDTA, etc… • - increases fertilizer assimilation
Functions of Humic Substances for Turf Fulvic Acid: biologically stimulating fraction D. Improves overall turf health which leads to: - relief from environmental stress, especially drought and frost damage.* - Improved resistance to : insect damage, viruses & pathogens *note- There is a ceiling effect and must be applied before pressure and continually.
Functions of Humic Substances for Turf *note- There is a ceiling effect and must be applied before pressure and continually.

Functions of Humic Substances for Turf Fulvic Acid: biologically stimulating fraction • E. Stimulates enzymatic functions: • RNA and DNA synthesis • catalysis of many biological synthesis pathways
HumiSolve: Dry soluble humic/fulvic concentrate - only need a fraction compared to raw humic substances! - easier to handle than raw - immediately available for today’s turf - stable over time (liquid humic acid degrades) - contains both humic and fulvic - no heat processing for higher efficacy
Ful-Power Fulvic Liquid: -compatible in all pH ranges (unlike the humic faction) -great for foliar applications -enzymatically extracted (replicates nature…who does it better?) …true fulvic not fulvate …contains beneficial microbes, enzymes, and phytostimulants -wetting agent (adjuvant) qualities and is effective penetrant …makes other sprayed materials more effective/amplified …helps pull other materials past the leaf membrane
CONCLUSIONS: Materials that are environmentally responsible and an important part of sustainable soil management. Products that help pay for themselves by reducing inputs and stimulate soil life/biota. A few take home lessons: • *Improved turf health (color, consistency, better root structure, thickness) • *Resistance to environmental, and pest pressures (drought, insect, pathogenic, virus) • Helps efficiency of fertilizers and reduces their leaching: leads to higher performance at lower rates and increased savings. • Stimulates seed germination (rate and percentage).
