FAQ

A water storage granulate is a network of hydrophilic polymers that absorbs and stores water in order to release it again when required. A hydrogel is the gel forum of this polymer network created by water absorption. It stores the excess water after rain or artificial irrigation and releases it to the soil (and especially to the area around the plant's roots) when it dries out again.

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.

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): 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 for the plant's ability to maintain its structure and upright itself against gravity. As turgor decreases, 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 is mainly used to absorb water and the minerals dissolved in it. Roots also ensure that plants are fixed 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.

Superabsorbents, or superabsorbent polymers (SAP), are materials that can absorb and store large amounts of water relative to their own weight. This property 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 produce biodegradable superabsorbent polymers (SAP). Our environmentally friendly superabsorbents contain no microplastics and thus help to minimize water loss, reduce erosion and improve soil structure. They support sustainable agriculture and reforestation without compromising soil or water quality.

Polygrain is an advanced, environmentally friendly product that has been specially developed for use in agriculture and horticulture. It serves as a soil additive that offers various advantages. Detailed description

Its mode of action is comparable to that of a sponge. It can store up to 200 times its own weight in water and the nutrients dissolved in it. These are released to the plant's root environment as required via the capillary effect. Due to its lifespan of up to 5 years, this process is repeated until the granules have been broken down by the soil organisms.

POLYGRAIN is an agricultural product that is based on many years of development and has been scientifically tested. Available on the market since 2023, POLYGRAIN builds on sound experience and offers innovative solutions for use in agriculture.

No, polygrain is not harmful to the environment. In fact, it is an environmentally friendly option for agriculture and horticulture as it is biodegradable. The product was specially developed to offer an environmentally friendly alternative in these areas. It does not accumulate in the plants, which means that it leaves no harmful residues in the plants that are harvested and consumed.

Yes, polygrain is biodegradable. It is broken down by various macro- and microorganisms in the soil. This natural degradation process allows Polygrain to leave no long-term negative impact on the environment after its use. This makes it an environmentally friendly choice for use in agriculture and horticulture, as it helps to maintain soil health and quality without harming the environment.
