VANKO 97 EOOD

VANKO97 Ltd.

For 24 years now, VANKO97 Ltd. has represented and distributed TERAWET products, holding the brand and trademark rights — respectively the exclusive rights for distribution of the group of superabsorbents based on cross‑linked potassium salts of acrylic acid.

These are soil conditioners that aerate and drain the soil through the shrink‑and‑expand cycle of their granules during water absorption and the subsequent release of moisture to the root system. This keeps the soil loose and moist, while reducing water needs by half — both in time and quantity — because the swollen polymer creates a water reserve used exclusively by the plant roots. Saving 50% water is accompanied by a 30% reduction in water‑soluble additives (fertilizers and other products) and a 25–35% increase in yields. The product is completely environmentally safe and is supplied with all required permits, certificates, licenses and control documents. TERAWET hydrogels have a long‑lasting effect of up to 10 years with a single application and are a serious alternative in combating drought. They are suitable for all types of plants.

Products

TERA WET

Moisture‑retaining superabsorbent for soil improvement

PROVEN!
Drought is no longer a problem with the hydrogel‑type soil conditioner “Superabsorbent TERAWET®”.

ADVANTAGES OF TERAWET

• reduces irrigation needs by more than 50%
• saves over 30% of used fertilizers
• increases yields
• remains effective for 7–10 years after a single application
• ensures fast absorption even during short rainfall
• can be applied together with fertilizers and other water‑soluble additives
• improves aeration and drainage

TERA WET is a potassium salt of acrylic acid in the form of a cross‑linked polymer whose water‑saturated granules expand up to 500 times their volume, ensuring long‑lasting moisture for the plant.

The duration of the stored water effect reaches up to 10 years at application rates of 3–5 kg per decare or 5–10 g per plant for perennial vegetation.

TERA PILL

TERA PILL are 15‑gram tablets containing nutrients, microelements, superabsorbent and mycorrhiza, providing a combined effect of growth accelerator and immune stimulant.

They are placed under or around each plant in doses of 1–4 tablets depending on the type and age of the plant.

TERA COMPOST

TERA COMPOST — naturally decomposed mechanical mix of dried residues from oil mills producing neem, karanja and castor oils. It has high nutritional value, enriching the soil with N/P/K 5/1/2 in a highly absorbable form. It contains salannin, nimbin, azadirachtin and karanjin, providing strong insecticidal, fungicidal and nematocidal properties when applied linearly in doses of 100 g/m in planting beds.

TERA FORCE

A combined product with nourishing, moisture‑retaining and growth‑stimulating effects in tablet form. Contains natural humates, superabsorbent, organic chitin‑type additives and beneficial soil bacteria.

TERA SULF

TERA SULF — naturally extracted sulfur (90%) granulated with natural bentonite for soil enrichment, pH balancing and maintaining optimal moisture and aeration. Dosage: 1.5–3.0 kg per decare when applied evenly.

TERA HUM

TERA HUM tablets (20 g) contain natural humates extracted from mineral deposits and marsh sediments for soil enrichment, applied directly in the root zone or through drip irrigation after complete dissolution. The solution can also be used for foliar feeding.

TERA OIL Neem

Neem oil — an insecticide repelling sucking and chewing insects (cabbage butterfly, pear psylla, beetles and household pests) with a strong repellent effect. Requires foliar spraying at 50 ml per 15‑liter sprayer with proportional dilution.

TERA OIL Karanja

Karanja oil enriched with superabsorbent for soil application or water‑soluble emulsion for foliar spraying.

TERA GEL

TERA GEL is a powder product made from biodegradable polymer which, when dissolved in water at 5 g/liter, forms a gel coating the root system, ensuring moisture during transport and planting.

Application:

1. Spring and Autumn
When planting fruit trees, roses, raspberries, currants, aronia, blackberries, vineyards, strawberries and other perennial shrubs and trees, it is recommended to apply 5–8 g (for shrubs) and 10–15 g (for trees) of dry TERAWET in the planting hole, then cover, compact and water thoroughly to allow the granules to swell and form a water cushion.

2. Preparing nurseries and greenhouses
Mix 1 kg TERAWET with 1 cubic meter of soil to create a medium for accelerated germination and seed development.

3. Planting vegetables
(potatoes, beans, peppers, tomatoes, cucumbers, etc.) as well as technical and essential oil crops (tobacco, lavender, mint, lemon balm, valerian, etc.) — apply 2.0 kg per decare of dry TERAWET evenly in the furrows or beds under the seedlings together with fertilizers. Subsequent watering ensures initial moisture, stable growth and increased yield.

4. Root dipping in gel paste
Dipping roots in a paste made from 5–8 g TERAWET100 per liter of water ensures 100% survival during transport and transplanting. The same paste can be used for rooting cuttings and seed stratification.

5. Field crops
(alfalfa, corn, wheat, sunflower, rapeseed) — apply 3 kg per decare or 800 g per decare directly under each seed using seeder and fertilizer spreader attachments for three consecutive years.

6. Lawn establishment for gardens, sports fields, landfills
Apply 15–20 g/m² of T100+T400 as a “sandwich layer” under the grass mixture, followed by compaction and watering.
