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

slide2

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)

slide4

Brief Properties : Structure / Size

Humic: soil conditioning fraction

Fulvic: biological fraction

slide6

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.

slide7

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)

slide8

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

slide9

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.

slide10

Functions of Humic Substances for Turf

Fulvic Acid:

biologically stimulating fraction

A. Improves root structure and mass, especially adventitious roots.

slide11

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
slide12

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
slide13

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.

*note- There is a ceiling effect and must be applied before pressure and continually.

slide16

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
slide17

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

slide18

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

slide19

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).
