🌱 Humic acid application in lawns – irrigation + dosage table

Humic acid dosage Irrigation (mm) Water (L / m²) Application depth When recommended

5 ml / m²                  3–5 mm             3–5 L                5–8 cm        Maintenance treatment, good soil

10 ml / m²                 5–8 mm             5–8 L                8–12 cm       General, best practice

10 ml / m²                 8–10 mm            8–10 L              10–15 cm     Dry period, intensive need

15 ml / m²                10–15 mm            10–15 L            15–20 cm      Degraded, sandy soil

❌ >15 ml / m²         20+ mm               20+ L            below 25 cm     Ineffective, not recommended

Target depth: 10–20 cm

This is the zone where:

> most active roots are present,

> nutrient uptake occurs,

> the soil colloid system is functioning,

> CEC increase really matters.

❌ If it only stays on the surface → its effect is limited

❌ If it goes below 40 cm → the lawn barely "uses" it

It is good for water to go deep (reserve)

The job of humic acid is to:

make the upper root zone more stable,

bind water and nutrients there.

➡️ It should not be washed away, but incorporated into the upper soil layer.

Imagine it like this

> 🪨 sand → too big, it settles immediately

> 🧂 salt → completely dissolves

> ☁️ colloid → floats between the two 👉 you can't see it, but it works

What are colloids in soil?

The most valuable parts of the soil:

> clay minerals

> humus / humic acid

> humic substances of leonardite origin

These are all colloid-sized. Why are colloids important? Because colloids:

> ⚡ have a charge (mostly negative)

> 🧲 bind nutrients (Ca²⁺, K⁺, Mg²⁺, etc.)

> 💧 retain water

> 🌱 "bind" nutrients to the roots

In one sentence:

A colloid is the "invisible warehouse" of the soil: it binds nutrients and water and gives them to the plant when it needs them

General statement: water stays where it has something to bind to.

Leonardite does not give a quick effect, but over time builds up the soil system in which water and nutrients can finally remain.

Does it bind water? NO! I mean not in the sense of glue. It binds water to soil colloids, and thus keeps it in the root zone.

Clay soil contains a lot of soil colloids. 👍

The clay minerals themselves are colloidal in size (very small particles).

These particles are negatively charged, therefore:

they bind water,

they bind nutrient ions (K⁺, Ca²⁺, Mg²⁺, NH₄⁺),

they slowly, continuously release them to the roots.

For this reason, clay soil is a good nutrient storehouse, but:

it compacts easily,

it can be airless,

it either retains too much water or it "sticks".

Important professional tip 🌱

👉 it doesn't matter what kind of colloid it is:

clay colloid = good nutrient retention, but can be structurally problematic

humus / humic acid colloid = this is what stabilizes the structure

→ more crumbly soil

→ better aeration

→ less water runoff and evaporation loss

The humic acids in leonardite do not leave water on the soil surface as free water.
They bind the water to the soil particles in a colloidal state.
This water does not evaporate quickly because it is not "free standing".

What happens:
☀️ less surface evaporation
💨 less drying wind effect
🌱 the water remains in the root zone, from where the plant can gradually absorb it

Millions of years of plant matter that did not become coal, did not remain peat, but stopped in a state where:
> concentrated humic acid
> concentrated fulvic acid
> concentrated binding capacity

Leonardite: is not a "spectacular input" (like a leaf fertilizer), not an immediate coloring effect, but a basic system improver.

The soil is now "thirsty" not only for water, but also for nutrients - even if it has nutrients.

We are increasingly seeing:

❗️deficiency symptoms despite good supply

❗️nutrients that "extinguish" each other

❗️unstable stocks, hectic reactions

This is no coincidence.

👉 The problem is often not with the quantity, but with access.

The organic matter content of the soil decreases, the system loses its buffering capacity, the nutrients:

– are bound

– are washed out

– or come into antagonism with each other

The plant "starves" while the nutrient is right next to it.

💡 The solution is not always to give more, but to make the soil-root connection functional again.

Humic and fulvic acids do not work as nutrients, but as system improvers:

✔️ they help the uptake of microelements

✔️ they reduce antagonisms

✔️ they improve root activity

✔️ they make the entire system more stable

👉 Yield increase is not a goal, but a consequence.

👉 Soil is not a medium, but a living system

This is the key:

Not because there are fewer nutrients, but because the system that operates them has ceased to exist.

The classic symptoms:

> yellowing, purple

> scorching with good nutrient levels

> hectically occurring deficiencies (even within a field)

=> unstable system => unstable yield

> Why doesn't foliar fertilizer solve this?

In the short term:

✅ alleviates symptoms

❌ does not eliminate the cause

On the foliage:

> micrograms enter

> no buffering

> no storage

! That's why it's said:

"You have to give more every year, but it's worth less and less."

? Where does humic acid come in (and why does it matter what kind)?

Humic acid is not a nutrient, but a system enhancer.

On the soil side:

> chelates microelements

> dissolves bound forms of P, Fe, Zn

> reduces antagonisms

> increases CEC (cation exchange capacity)

On the root level:

> stimulates lateral root formation

> improves ion uptake

> reduces salt and drought stress

! That is why we say:

not more nutrients,

but more access

> Why is this problem exploding now?

> extreme weather

> intensive cultivation

> high salt load inputs

> low organic matter replenishment

The system is tired

Soil depletion is no longer a quantitative problem, but a functional one:

> There are nutrients in the soil, but they are not available to the plant.

▸There are three main reasons for this:

> Nutrient antagonisms

Certain elements "hit each other":

> too much K → Mg, Ca deficiency

> too much P → Zn, Fe blocking

> high Na, NH₄⁺ → root stress

! This is a deficiency symptom from the outside, a chemical lock from the inside.

▸ Organic matter deficiency

The soil is a colloidal system – without humus:

> no buffering

> no binding

> no gradual decomposition

! Therefore:

> the nutrients are washed out, or

> bind, or

> become toxic.

▸ Weakening of the root-soil connection

In compacted, biologically inactive soil:

> the roots do not "search", they just vegetate

> ion uptake deteriorates

> the stress hormone level (ABA) increases

The percentage is not marketing, but shows how many active molecules are actually working.

What does it mean in practice?

> 5–10% humic acid→ additive, supplement, "coloring agent"

> 20–30% humic acid → medium effect, already noticeable, but a compromise

> 40–55% humic acid (from leonardite) → systemic intervention, soil-root connection

The plant does not respond to the amount of liquid, but to the number of active humic acid molecules

🌿 "Humic acid" used in foliar fertilizers

What does this mean in practice?

> Mostly an additive, not the main active ingredient

> Often:

> Low humic acid content (1–5%, sometimes 8–10%)

> Often synthetic or by-product humate

Main purpose:

> Chelating microelements

> Stabilizing spray liquid

> Rapid "boost" through the leaves

📌 Where does it work?

> On the leaves

> Short-term

> Fast, but superficial effect

📌 What does it not do?

> Does not build soil

> Does not improve the root zone

> Does not work with the system in the long term

👉 It's like a vitamin injection: useful, but not a foundation.

🌱 Leonardite-based humic acid

This is a completely different category.

> Natural origin: oxidized carbon (leonardite)

> Very high humic and fulvic acid content

> Complex, biologically active molecular structure

📌 Where does it work?

> In the soil

> In the root zone

> In the soil-plant system

📌 What does it actually do?

Improves the cation exchange capacity of the soil

Helps root formation

Increases nutrient and water utilization

Provides stress tolerance (drought, salt, heat)

Activates soil life

👉 This is not an additive, but a system-building raw material

Dilution

> 1 ml humic acid / 1 liter of tap water

> If using a watering can:

→ 10 ml humic acid for 10 liters of water

Application

> Best on already watered or slightly damp lawn

> Or water with clean tap water after application

Timing

> Early morning or evening

> Every 2–3 weeks is plenty

But what about the chlorine content of tap water?

No problem

Chlorine evaporates quickly

>Humic acid: buffers water, binds salts, improves soil water retention

> Specifically helps with the effects of "hard" tap water

What will you see?

>deeper green color

> denser lawn

> better drought tolerance

> less burnout in summer

The plant does not "eat" humic acid.

And this is the key to it all.

Humic acid is not a nutrient.

It is not a fertilizer.

It is not a quick fix.

! Humic acid regulates the root environment:

• helps retain water

• helps absorb nutrients

• reduces stress in the root zone

If you understand this, then you will also understand why you should not feed the plant, but support the system

Mixing

>Mix in a watering can or bucket:

> 10 liters of tap water + 10 ml of humic acid

>Use this only for application, not for complete watering.

Application process

1. First, lightly water the grass with a hose (so that the soil is moist)

2. Pour the humic acid solution evenly over the surface of the lawn

3. Then, water it again with a hose → wash it into the root zone

Frequency

> Every 2–3 weeks is enough

> In the summer heat, preferably in the afternoon or evening

Leonardite is not an "ingredient", but the basis of the entire humic acid technology.

This is the natural raw material from which a high active ingredient, stable and biologically active humic acid can be produced.

Leonardite is a natural mineral of oxidized lignite origin, which has an extremely high humic and fulvic acid content.

This is not fresh organic matter, but a humus precursor that has stabilized over millions of years.

Why is it a better raw material than other humus sources?

1. High natural humic acid content

Leonardite:

> concentrated source of humic acid

> not "diluted" or partially decomposed organic matter

> therefore, a high effect can be achieved with less carrier material

! This is the basis for a preparation to be able to stably contain humic acid above 52%.

Stable, biologically active structure

Humic acid from leonardite:

> does not disintegrate when diluted

> does not precipitate in irrigation water

> remains active in the soil for a long time

! This is especially important in stressful conditions (drought, salt load, depleted soil).

More effective soil-root connection

Leonardite-based humic acid:

> improves soil structure

> increases water and nutrient retention

> helps the microbiological activity of the root zone

! It does not replace, but builds a system

More mobile in the soil

Non-ionized humic acid:

large molecules,

tends to "sit" on the surface,

has a harder time getting down to the root zone.

Ionized humic acid:

well dispersed in water,

moves with irrigation water / precipitation,

really gets to the root.

2️⃣ Can bind nutrients immediately

Ionized humic acid:

already has a negative charge,

does not need to be "activated" in the soil.

➡️ It immediately binds:

Ca²⁺

Mg²⁺

K⁺

NH₄⁺

microelements (Fe, Zn, Mn)

This is the basis of the CEC-increasing effect.

3️⃣ More effective in stress situations

In ionized form:

it is incorporated into the colloidal system faster,

it helps better in drought, salt stress, cold soil,

even a smaller dose gives a noticeable effect.

➡️ Therefore, it is not the liter that counts, but the active fraction

Leonardite is particularly important because:

> the quality of humic acid is determined not by the label, but by the raw material

> stable, concentrated and biologically active humus source

> allows for lower doses and longer duration of action

! That is why professional humic acid solutions with high active ingredient content are based on Leonardite.

Because:

> more expensive raw material

> more technologically demanding processing

> requires laboratory and stability testing

! However, this is the only way to achieve a real, measurable active ingredient level

Leonardite is not an "ingredient", but the basis of the entire humic acid technology.

This is the natural raw material from which high active ingredient content, stable and biologically active humic acid can be produced.

Leonardite is a natural mineral of oxidized lignite origin, which has an extremely high humic and fulvic acid content.

This is not a fresh organic material, but a humus precursor stabilized over millions of years

Why is it a better raw material than other humus sources?

1. High natural humic acid content

Leonardite:

> a concentrated source of humic acid

> not a "diluted" or partially decomposed organic material

> therefore, a high effect can be achieved with less carrier material

! This is the basis for a preparation to have a stable humic acid content of over 52%.

Stable, biologically active structure

Humic acid from Leonardite:

> does not disintegrate when diluted

> does not precipitate in irrigation water

> remains active in the soil for a long time

! This is especially important under stressful conditions (drought, salt stress, depleted soil).

More effective soil-root connection

Leonardite-based humic acid:

> improves soil structure

> increases water and nutrient retention

> supports the microbiological activity of the root zone

! It does not replace, but builds a system

What happens in the soil without precipitation?
> The available water is minimal, capillary water disappears quickly
> Heat load and evaporation are extreme, the root zone is under stress
> The nutrient is present, but not mobile, does not reach the root
The plant does not grow, but survives

In this state, it is not necessary to "administer" nutrients, but to stabilize the root environment.

What does 52% humic acid do in such a situation?
1./ Micro-water retention (not irrigation!)
The high humic acid concentration:
> forms a colloidal structure in the soil
> binds microscopic water fractions
> slows down evaporation in the root zone

It does not "make water", but retains what is still there.
Root protection under extreme stress
Humic acid: 
> buffers heat and salt stress
> reduces oxidative damage to root cells
> forms a protective layer on the root surface
! The plant does not stop, but remains alive and can react.

Root activation even in the event of water shortage
Stable, well-dissolved humic acid:
> stimulates lateral root formation
> increases the root surface
> helps the root "seek" function
! The root does not wait for rain, but remains active.

What does 7–8% fulvic acid add?
Key role in drought
Fulvic acid:
> has a very small molecular size
> passes through the cell wall
>chelates minerals (Ca, Mg, Fe, Zn, etc.)

! What the root cannot absorb on its own, it brings to it.
"Transportation system" without water
In the presence of fulvic acid:
> the nutrient is mobilized
> the root cell opens
> the useful elements enter the plant
! That is why it makes sense to use it even in drought.
Why is the high (52%) active ingredient important in this case?

Because: 
> at low doses there are not enough active molecules
> weak humic acid does not buffer, it is only "present"
> in drought only the concentration matters
! Little water + high stress = high active ingredient required

Yes, unfortunately it happens on the market.

For some products, the indicated humic acid content:

> does not apply to the final product, but to the raw material, or

> the preparation is sold in pre-diluted form, with a low actual active ingredient content.

This is not illegal in itself if it is stated accurately on the label and in the documentation, but it can be misleading for the farmer if the following is not clearly stated:

> the actual humic acid and fulvic acid content, the recommended dosage, the amount of active ingredient applied per hectare.

What makes a correct product different?

In the case of a reliable humic acid preparation:

> the active ingredient content applies to the final product,

> it is supported by laboratory-verified values,

> dilution is exclusively an application technology, not part of the sale.

In the case of Ecosy products, 52% humic acid + 7–8% fulvic acid is the actual active ingredient content of the concentrate placed on the market, and dilution occurs during use, for better utilization.

Important difference:

> we do not sell it diluted – but concentrated and use it diluted.

> New generation concentrates with 52% ionized humic acid content bring real biological improvement in the soil.
> Due to its stable, easy-to-handle consistency, it does not settle, does not separate, and remains homogeneous for a long time.
> Easy to apply: works effectively in a fifteen-fold dilution.
> Also highly recommended for hydroponics, where the active ingredient exerts its effect directly in the root zone.
> The farmer can safely use it on all soil types and in all crops - risk-free, reliable effect.

The products are manufactured in an industrial park in Szekszárd, in a HACCP-licensed production environment, with controlled raw materials and production processes.

The recommended operating dose of Ecosy humic acid-based preparations is 20 liters / hectare.

This recommendation is not based on multiple applications, but on a single, concentrated application.

The high active ingredient content (52% ionized humic acid + 7–8% fulvic acid) allows for substantial active ingredient input to occur in one application, without changing technology.

The recommended operating dose is based on a single application: due to the high active ingredient content, multiple treatments are not required, which reduces the number of machine passes, fuel consumption and additional costs

HUMINAgro, HUMINXtra and HUMINVital are highly purified organic-mineral substances. Their purpose is to activate soil life, improve water retention and more efficient nutrient uptake.

General application recommendation:
• 20 liters/hectare diluted in 280 liters of water (1:15) in horticultural, field and plantation crops
• Foliar fertilizer: spraying or irrigation
• Soil treatment: before planting and during vegetation

Vegetables

Soil treatment:
Application: soil spray, row spray, irrigation system.
Miscibility: compatible with all fertilizers and nutrient solutions.
Advantages: fast rooting, water retention, stress tolerance.
Seedling cultivation:
• 1–2 liters of concentrate / diluted in 14-28 liters of water
• Stimulates root development, reduces stress
After planting:
• Apply 2–3 times, every 2 weeks

Orchards – apple, pear, sour cherry, cherry, plum
Soil treatment: 20 liters/hectare, 280 liters of water.
Most effective from early spring before budding.
Application: row-based soil spraying, irrigation system, strip treatment.
Mixability: calcium, microelements, nutrient solutions.

• 20 liters / hectare diluted in 280 liters of water applied to the soil
Vegetation treatment:
• 10 liters of concentrate diluted in 140 liters of water / hectare on foliage
Drought support:
• Fulvic acid provides rapid chelation, improves water retention

Don't worry!

If there is too little water when applying humic acid:
> the humic acid does not spread properly,
> more goes to some spots, less to others,
> the effect will be spotty.
It does not cause any problems, it just does not give the result we expect.

With too little water:
> larger spray droplets are formed,
> fewer droplets reach the soil surface,
> the chance of runoff increases (it does not stay where it should).
Droplet size and coverage deteriorate, the active ingredient is not optimally delivered to the root zone.

In case of too thick a spray solution:
> nozzles do not work optimally,
> pressure fluctuations may occur,
> the accuracy of application deteriorates.
Mechanical problems, this is an operational risk and not plant damage.

What DOES NOT happen when using less water?
It is important to state that the Ecosy product
> does not scorch
> does not burn
> does not stress the plant
> does not damage the soil
It is simply not utilized perfectly.

When is less water not a problem?
> If the product dosage (L/ha) is exactly followed
> If the spraying gives even coverage
> If the application is not done in extreme heat
> If the product is not scorching (Ecosy is not)
In this case, the water is only a carrier, the plant does not "drink" the spray liquid, but the humic acid is transferred to the soil surface / root zone.

When can too little water be a problem?
This is not phytotoxicity, but a technological problem:
> the distribution will not be uniform
> spotty application
> nozzles do not work well
> large droplets → runoff, poor coverage
That is why we specify a minimum dilution (e.g. 1 : 15–18)

52% ionized humic acid – 7-8% fulvic acid with products
HUMINAgro 1 L, HUMINXtra 5 L, HUMINVital 20 L

1) General lawn care dosage
100 ml concentrate / 10 liters of water / 10 m²
This = 1 liter / 100 m² 2–3 times a year.
What is it good for?
healthy green color, moisture retention → less watering. better root formation, thicker, stronger lawn

2) Regenerating, accelerating treatment (yellowing, spotty, weak grass)
150–200 ml / 10 liters of water / 10 m²
Timing: once every 2–3 weeks, 2–3 treatments.
Effect:
regeneration after stress, strong greening, root rehabilitation, spot closure

3) Larger lawn areas (100–200–500 m²)
Surface: Concentrate: Water: Note:
100 m² 1 liter 20–40 liters Sprinkler/sprayer
200 m² 2 liters 40–60 liters Can be refilled on the go
500 m² 5 liters 100–150 liters Ideal with a sprayer truck

4) Professional users (park maintainers, municipalities)
5–10 L concentrate / 1000 m² / once a month
The goal here: fast growth, large root mass, extreme drought tolerance.

5) Mixing ratio 52% active ingredient → highly concentrated, therefore: 1 liter concentrate + 20–40 liters of water → 100–150 m² surface. When spraying, a fine mist is best (do not run).

6) When to apply?
> early morning or evening
> on slightly moist soil
> before or after nutrient application
BUT, NEVER above 30°C, in strong sunlight!

7) Humic acid + NPK together?
The best combination:
Humic acid → water + nutrient retention
Fulvic acid → acceleration of nutrient absorption
NPK → growth, greening
→ up to 30–40% better nutrient utilization
intensive greening within 7–10 days

8) Typical results
7 days: greening, shoot initiation
14–21 days: spectacular thickening
1–2 months: drought tolerance, stable root system
3–4 months: maximum compact lawn

1️⃣ After planting / transplanting (root initiation)
Purpose: faster rooting, stress reduction
By irrigation:
5–10 ml / 10 liters of water
applied directly to the root zone
within 3–7 days after planting

2️⃣ Vegetative development phase
Purpose: maintaining root activity, improving nutrient utilization
Mixed in irrigation water:
1 ml / 1 liter of irrigation water
Every 2–3 weeks
can be applied together with nutrient solution

3️⃣ Intensive growth / bud formation
Purpose: maintaining uniform stock, vitality
In irrigation water:
0.5–1 ml / liter of water
Every 2–3 weeks
excessive doses should be avoided

4️⃣ Important professional notes
Due to the high active ingredient content, a low dose is sufficient
Not scorching, not plant stress
Does not replace nutrient solution
Not a pesticide
Can be easily integrated into existing technology

Application and application technology

Forage-producing arable land
Recommended application once a year
Recommended dose: 15–20 liters / hectare, depending on soil condition and cultivation intensity
Dilution: typically 1 liter of product with 15–18 liters of water, adjusted to the application technology
Arable land spraying, adaptable to existing technology

Pastures (main application area)
Once a year, typically at the beginning of vegetation
Recommended dose: 10–12 liters / hectare on pastures in average condition
In less favorable, stressed areas: 15–20 liters / hectare
Dilution: typically 1 liter of product with 15–18 liters of water
Purpose: activation of the root zone, improvement of water retention capacity and regeneration of the turf support
The degree of dilution serves the technical implementation of the application and uniform coverage; it does not affect the amount of active ingredient applied per hectare

Pastures (direct relationship)
ECOSY improves:
the root zone of the turf,
water retention,
regeneration after stress.
Consequence in livestock farming:
more uniform pasture quality,
less "burnout" in drought,
more stable animal intake.
This is a direct economic effect.

Forage crops (indirect but measurable)
Arable forage (corn, alfalfa, grasses):
ECOSY:
helps nutrient utilization,
improves root development,
reduces stress.
Consequence:
more uniform yield,
more stable content,
more predictable forage quality.
This reduces the risk of livestock farming

Our high-active ingredient humic and fulvic acid-based products can also be used safely and effectively in hydroponic systems – specifically to support the root zone and nutrient utilization.
Why does it work in hydroponics?
> Root activation: stimulates lateral root formation, denser root tissue.
> Nutrient utilization: chelating effect → better micro- and macronutrient uptake.
> Stress tolerance: more stable growth even under pH, EC and heat stress.
> Root environment: supports root surface activity, with a clear solution.

Application recommendation (general)
> Mixed in nutrient solution: low, continuous dose (microdose principle).
> EC/pH: does not upset the set values, but it is worth re-measuring when using a new nutrient solution.
> System types: NFT, DWC, drip, aeroponics.

Practical tip: start with half the dose when starting out, then adjust to the target value after 1–2 cycles. This way you can clearly see the root reaction without the system being "pushed too far".
What can you expect?
Stronger, whiter roots
More uniform growth
Better nutrient efficiency with the same EC
