The superabsorbent effectively stores more than 300 times its own weight in water and the plant nutrients dissolved in it, thus promoting plant growth even during long periods of drought.
Microorganisms completely break down the superabsorbent in the soil and it retains its effect for a period of 3 to 5 years.
The POLYGRAIN water and nutrient retainer is an all-in-one superabsorbent hydrogel capable of creating an additional reserve of water and nutrients in soils and substrates available for long periods of time (3-5 years).
It consists of 58% cellulose, 40% superabsorbent (crosslinked potassium polyacrylate) and 2% water-soluble NPK + Mg starter fertilizer.
Water absorption capacity (deionized water): < 200 g/g granules.
Particle size: 85% between 1 ms and 4 ms
Water content: < 8%.
POLYSORB water and nutrient retainer is a hydrogel with a high capacity for water and nutrient retention developed to increase the efficiency in the use of water and fertilizers, as well as serving as an additional and long-lasting reserve of water and nutrients available to plants, especially in times of drought and scarcity of water and soil resources in substrates and cultivable soils.
It is made up of 100% superabsorbent (crosslinked potassium polyacrylate) with a slight fertilizing effect (< 16% water-soluble P2O).
