One raw material
Lake sapropel and nothing else. No sewage sludge, no municipal waste, no animal by-product, and nothing added.
Made to order
Bottle to bulk tanker from one production line, so a trial litre and a container come from the same material.
Shipped worldwide
Bottle, canister, drum, IBC or bulk — with the export and registration dossier included.
The material
What sapropel is, and why soil answers to it
Sapropel is a centuries-old sediment from the bottom of freshwater lakes: plant and animal matter broken down by bacteria under almost no oxygen. What survives that process is a colloidal humus complex — not a salt, not a synthetic chelate — carrying humic and fulvic acids, amino acids, vitamins, enzymes and the whole macro- and micro-element spectrum in a form roots can actually take up.
A humus complex, not a salt
A colloidal complex of humic and fulvic acids, amino acids, vitamins and natural enzymes, rather than a dissolved mineral salt.
It binds what you don't want
Humates lock up heavy metals and radionuclides and help break down chemical residues, so less of them reaches the crop.
It holds water
Colloids improve structure and cation exchange in both sandy and heavy clay soils, cutting irrigation demand and crust formation.
What it does, in the soil and in the plant
In the soil
- Rebuilds structure and feeds the native micro-flora
- Increases water-holding capacity and drought resistance
- Loosens and aerates heavy clay; cuts water and nutrient loss in sand
- Regulates pH and chelates metal ions so roots can take them up
- Binds heavy metals and radionuclides and blocks their route into the plant
- Reduces leaching of soluble mineral fertiliser from the root zone
In the plant
- Promotes uptake of nitrogen, phosphorus and potassium; suppresses nitrate build-up
- Corrects iron shortage and prevents chlorosis
- Accelerates cell division and root development — germination up to 10–15 days earlier
- Raises resistance to disease, pests, heat and frost
- Increases the vitamin and mineral content, taste and shelf life of the crop
- Improves enzyme efficiency in respiration and sugar, protein and chlorophyll synthesis
The product

from €3.001 L bottle · ex works, freight extra
Standard packaging is the 1 L bottle. Any volume can be produced to order — 5 L, 20 L, 200 L, 1000 L IBC or bulk in tanks. Prices are ex works Vilnius and exclude VAT, freight, duties and any registration or certification required in your country. Volume pricing is in the table below, and the exact all-in figure comes with your quote.
Other formulations
Nitrogen-forward, autumn hardening, calcium and potassium variants of the same sapropel base can be produced to order against a firm volume. They are not stocked and are not offered here, because each one needs its own accredited analysis before we will put numbers to it. Tell us the crop and the problem and we will quote the production run.

What goes into it
One raw material: sapropel dredged from freshwater lakes. No sewage sludge, no municipal waste, no animal by-product. Nothing is added — no GMO material, no hormones, no preservatives, no pesticides. This is a statement about how the product is made, not a laboratory finding.
In the field
Rates, timing and what to expect
Standard working dilution is 1 part SOILFERT to 250–350 parts irrigation water. Apply the solution directly into the soil, through drip or as a root drench, every 15–21 days across the season.
Dilution
1 : 250–350 with fresh irrigation water. At 6–8 litres of water per square metre this gives an even, low-salt feed.
Field norm
20–40 litres per hectare per application, every 15–21 days through the growing season.
Seed treatment
10–20 ml of concentrate in 1 litre of water. Soak seed for 10–12 hours, then sow as normal.
Compatibility
Mixes with most liquid fertilisers. Run a jar test first, filter to 120 mesh for drip, and do not tank-mix with strong oxidising agents.

How the final price is calculated
The figures on this page are the product price at our gate. Your actual price depends on four things: the volume you order, the packaging you choose, the Incoterm we agree, and the distance to your destination. Where a market requires registration or certification before the product can be sold, that cost is quoted separately. Send us the destination and the quantity and you get one all-in figure, not a range.
The listed price includes
- The product in the packaging you choose
- Labels in your language, adapted to your national labelling rules
- Certificate of Analysis and Safety Data Sheet
- Commercial invoice, packing list and pallet specification
- A written application programme for your crop and soil
- Loading at our facility in Vilnius (EXW)
The listed price does not include
- Freight and transport insurance — calculated per destination and volume
- Customs duties, import taxes and clearance costs
- VAT, where it applies
- Registration or certification fees in the destination country
- Phytosanitary certificate fees, where the destination requires one
- Unloading and inland delivery at your end
What a season actually costs
| Crop group | Season norm | Applications | Indicative cost per hectare |
|---|---|---|---|
| Open-field vegetables | 150–240 L/ha | 8–12 | €330–528 |
| Greenhouse vegetables | 120–200 L/ha | 10–14 | €264–440 |
| Orchard and olive | 120–180 L/ha | 6–9 | €264–396 |
| Vineyard | 110–160 L/ha | 6–8 | €242–352 |
| Cereals and forage | 60–90 L/ha | 3–4 | €132–198 |
| Turf and landscape | 60–90 L/ha | 3–4 | €132–198 |
Calculated at the 200 L drum tier (€2.20/L), product only — freight to your farm is additional and depends on distance and order size. Set against a lower chemical-input bill, most growers recover the programme cost within the first season. Final programmes should be built on a soil analysis.

Questions
What growers ask before the first order
Is SOILFERT a fertiliser or a soil improver?
A soil improver first. The accredited analysis puts nitrogen at 2.2% and phosphorus and potassium below 0.2% on dry matter, so SOILFERT is not a substitute for your NPK programme. What it carries is the humic complex — 49.2% humic acids on dry matter — which works on the soil itself: structure, water retention, cation exchange and micro-flora. Run it alongside your mineral fertiliser only does the first job.
Can I run it through drip irrigation?
Yes. Dilute 1:250–350, filter to 120 mesh and inject as you would any liquid feed. It also works as a root drench, in fertigation tanks and in hydroponic systems at 1 L per 200 L of water.
Can I tank-mix it with my current programme?
In most cases yes, and many growers use it to reduce their mineral inputs rather than replace them outright. Run a jar test before the first mix and avoid combining it with strong oxidising agents.
Is it safe for people, animals and bees?
The safety data sheet records no acute eye, skin, inhalation or ingestion hazards and no chronic effects, with an acute oral LD50 of 7 500 mg/kg in rat. It is not classified as a dangerous good for transport. Avoid spraying directly onto open flowers.
How quickly will I see something?
Seedlings typically emerge and root 10–15 days earlier. Vigour and root mass usually show within one or two applications. Yield effects are seasonal and depend on the starting condition of the soil. We do not publish a yield figure, because we have no trial of our own to stand behind — ask us for a trial litre and measure it on your own crop.
Why is the price on request?
Because the number on this page is only part of it. The published figures are the product at our gate: 1 L at €3, falling to €2 per litre at container volume. What we cannot publish is the rest — freight and insurance depend on the distance and the size of your load, customs duties depend on your country, and some markets require registration or certification before the product can be sold at all. Tell us the destination and the quantity and we return one all-in figure you can budget against, usually within a business day.
Do you ship to my country?
We ship worldwide from Vilnius, Lithuania. Fertiliser registration in the destination country is normally the importer's responsibility — we supply the full technical dossier and support the application.
Can we sell it under our own brand?
Yes. Private-label production starts at 5 000 litres, and includes label design adapted to your market's labelling rules and language.
How much do I need for one hectare in a season?
For open-field vegetables plan on 150–240 litres per hectare across 8–12 applications; greenhouses 120–200 L/ha, orchards and olive 120–180 L/ha, vineyards 110–160 L/ha, cereals and turf 60–90 L/ha. At the 200 L drum tier that works out at roughly €132–528 per hectare for the whole season. Send us your crop and area and we will build the exact programme.
Can I try it before committing to a pallet?
Yes. We send a 1–5 litre trial with a written application programme for your crop, soil type and irrigation system, and there is no minimum order for it. Courier delivery usually takes 5–10 days. Most growers run one season on a drum before moving to IBC or container quantities.
Is it suitable for organic farming?
The analysis confirms the content is of natural origin only, with no GMO, hormones, preservatives, pesticides or pathogens detected. Organic certification is issued market by market — tell us your country and certifier and we will confirm the current status.
