Hydrogel for soil
„Estamos en Tenerife!“ (FC Tenerife stadium, Santa Cruz de Tenerife)
Hydrogel is an ecological biodegradable sorbent for potting soil that absorbs water and nutrients. Its main function is to absorb vital plant nutrition and water which it releases back to the potting soil as and when the plant demands it. Its expected life cycle is 7 – 9 years after which it starts to biodegrade.
Hydrogel’s pH is neutral and therefore harmless to fauna or flora and satisfies the strict norms of the EU.
Why is hydrogel important?
The amount of water kept in the root system of the plant is of paramount importance to the growth and quality of the plant. Hydrogel, unlike any ordinary potting soil has the capacity of retaining the water and necessary nutrients within the root system of the plant, preventing it from wilting during dry seasons and supporting its overall healthy growth and life.
Hydrogel comes in a form of crystal or powder, which jellifies upon contact with water or other liquids. The absorbent powers of hydrogel can be easily demonstrated by steering a tea spoon of crystal or powder into a pint glass of water.

Tips for winter
Hydrogel protects root system against the frost. If used on trees it can prevent them from wilting or going dry.
Hydrogel crystals absorb the water, therefore can serve as a protection in areas prone to flooding.
Variants of hydrogel
powder (0.2 to 0.8 mm) – use: flower pots, flower boxes, urban green, industry, food, sanitation
crystals (0.8 to 2.0 mm) – use: agriculture, horticulture, forestry, land reclamation, grassy field
Dosage of hydrogel
Flower boxes and pots
3 – 4 g/l (from 1-2 kg/m3)
(Depending on quality of the soil or substrate)
50 – 100 g/m2
2 – 3 kg/m3
Coniferous trees – planting 400 g/m3
Broadleaved trees – planting 800 g/m3
Coniferous shrubs – planting 15 g/per plant
Broadleaved shrubs – planting 30, 60, 120 g/per plant
(depending on the size of the growth )
Field–cultivation with plough, disk prior sawing (depth 15–20cm) 100 kg/ha
Field–at the time of sawing together with artificial fertilizer or along with planting the seedlings into the rows
20 – 25 kg/ha
3 – 4 g/per seedling
200 g/10 l of water
400 – 600 ml/per seedling
1 kg/100 l of water (hydro seeding)
100 l solution/per 800 ornamental trees
100 l solution/per 1000 seedlings forest trees
Re-vitalization of mature trees, shrubs - injection into up to 120 cm depth
(3 – 5 injections /per average mature tree)
The recommended dose depends on the type of soil. Generally stated, the sandy soils need higher dosage of Hydrogel than clay soils. Immediately following the first application of Hydrogel into the soil or the substrate, it is necessary to thoroughly water the plants in order to saturate the crystals (the roots will grow through the gel and feed on the nutrition and water it stores and contains)
