FAQ

Water storage granules are the dry, granular delivery form of our products (e.g. Polygrain, PolYGRAIN or Polygrain Tab 5 as tablets). When these granules come into contact with water, the particles swell considerably and form a hydrogel - i.e. a water-filled, sponge-like gel directly in the root area.

The way it works is based on so-called superabsorbers: these are polymers that can absorb enormous amounts of water - many times their own weight. When swollen, they retain the moisture in the soil and release it to the plant roots as required. At the same time, nutrients are also bound and are available to the plant for longer periods of time.

In short: granulate is the form you apply - hydrogel is created from it in the soil and acts like a water reservoir directly at the root.

Superabsorbents, or superabsorbent polymers (SAP), are materials that can absorb and store large quantities of water in relation to their own weight. This characteristic makes them particularly valuable for agriculture, especially in dry regions or during periods of drought, as they help to use water efficiently and retain moisture in the soil for longer.

At Green Legacy, we producebiodegradable superabsorbent polymers (SAP). Our environmentally friendly superabsorbents contain no microplastics and therefore help to minimize water loss, reduce erosion and improve soil structure. They support sustainable agriculture and reforestation without compromising soil or water quality.

Drought stress (or water stress) is the result of a lack of water in plants. It occurs when transpiration is greater than water uptake, resulting in a drop in internal pressure in the leaf cell. Abiscic acid forms in the roots and leaves and causes the stomata to close. This leads to a decrease in the internal CO2 concentration and subsequently to an inhibition of photosynthesis.

The plant evaporates more water than it can absorb - it comes under stress, grows more slowly and becomes more susceptible.

Plants wilt mainly due to a lack of water, which plays a crucial role in their life processes. Water is essential for various metabolic processes in a plant, including photosynthesis and nutrient transport. Step-by-step explanation of why plants wilt:

1. Water shortage: If a plant cannot absorb enough water from its surroundings, whether due to drought, poor irrigation or other environmental factors, a water shortage occurs.
2. Compensation by cells: Initially, the plant's cells try to compensate for this deficiency by using water from their own internal reserves.
3. Decrease in internal cell pressure (turgor): The turgor pressure is the pressure of the cell contents against the cell wall. Water helps to maintain this pressure. If there is a lack of water, the turgor pressure cannot be maintained as the cells begin to lose volume.
4. Reduced stability and wilting: Turgor is crucial to the plant's ability to maintain its structure and stand upright against gravity. As the turgor decreases, the plants lose their stiffness and begin to wilt as they are no longer able to support themselves effectively.

Wilting is therefore a visible sign that a plant is under water stress and does not have enough water available to maintain its vital functions.

Yes, too much water in the soil displaces the soil air and deprives the roots of their vital oxygen and, in the worst case, suffocates them. The plant's pumping system collapses and the above-ground parts of the plant are no longer supplied with sufficient nutrients or water.

Alongside the stem and the leaf, the root is the most important organ of a plant. It mainly serves to absorb water and the minerals dissolved in it. Roots also ensure that the plants are attached to their location and store reserve substances. The area of the soil influenced by the roots is called the rhizosphere. The rhizosphere is the habitat of various organisms such as nematodes or fungi, which are in constant interaction with the plants and thus reflect the nature of an entire ecosystem.

Polygrain - water storage granules with starter fertilizer, ideal for young plants.
Composition: 58 % cellulose, 40 % superabsorbent, 2 % starter fertilizer (NPK + Mg)

Polygrain Tab 5 - Polygrain in a handy 5 g tablet for manual planting and difficult terrain; no measuring, clean, easy to transport.

PolYSORB - pure superabsorbent (without cellulose & fertilizer) with maximum water retention; ideal for post-inoculation and for large-scale applications when no starter fertilizer is required.

Polygrain: up to 200-fold water retention, with starter fertilizer for a quick start; the cellulose is quickly broken down by microorganisms and promotes soil activity.

Polygrain Tab 5: identical effect to Polygrain, but as a tablet - ideal for individual plantings and manual application.

Polysorb: > 300-fold water retention, without fertilizer & cellulose - ideal for re-inoculation or when only maximum water retention is required.

Polygrain & Polygrain Tab 5: up to 200× its own weight.

PolYSORB: over 300× its own weight.

All products (Polygrain, Polygrain Tab 5, Polysorb) are effective for approx. 3-5 years. During this time, they can repeatedly absorb and release water and are then completely degraded by microorganisms.

Polygrain: for perennial crops such as vines, fruit, forest plants and in horticulture and landscaping - especially for young plants where a starter fertilizer is also required.

Polygrain Tab 5: particularly practical for individual plantings in viticulture, fruit growing and forestry or in difficult terrain where manual work is required.

Polysorb: suitable for larger crops and for subsequent inoculation when no starter fertilizer is required and maximum water retention is the priority (e.g. arable farming, viticulture, horticulture).

Polygrain, Polygrain Tab 5 and Polysorb are used in many areas of agriculture and forestry as well as in horticulture and landscaping. They can be used both for new plantings and for existing plant populations (by re-inoculation).

Typical fields of application are

• Forestry: reforestation, young plants, re-inoculation in stands
• Viticulture and fruit growing: new plantings, individual plantings, replanting
• Gardening and landscaping (GaLaBau): Parks, green spaces, roadside greenery, gardening
• Ornamental plant and vegetable cultivation: young plant cultivation, planting in commercial horticulture
• Lawn and sports turf areas: Turf, reseeding, new establishment
• House and allotment gardens: perennials, shrubs, hedges, trees
• Arable farming: Crops on sites with low water retention capacity

For irrigation-intensive crops such as in horticulture, the amount of irrigation can be significantly reduced. This reduces costs, saves working time and conserves water resources.

For crops or areas without irrigation - e.g. in forestry - failure rates of young plants are reduced and growth is accelerated. Maintenance work (e.g. mowing) and costs for manual replanting can thus be reduced.

Yes. In addition to the water supply, all products also improve the soil quality.Repeated swelling and shrinking loosens the soil, increases porosity and improves aeration in the root zone. At the same time, an optimal environment is created for microorganisms, which promote the decomposition of organic matter, mobilize nutrients and increase soil activity.

With Polygrain and Polygrain Tab 5, the cellulose, which is quickly broken down by microorganisms, also supports this effect.

The result: a more active, healthier soil that offers plants better growing conditions in the long term.
