Application notes
Tree and plant locations are often not ideally suited - the substrate has to be modified, woody plants have to be rehabilitated at the same time, clients are increasingly demanding growth guarantees.
Cost savings in communal greenery - more and more cities and municipalities are choosing STOCKOSORB® or GEFA Arbovit® for summer and tub planting, as the maintenance effort is significantly reduced.
More than less water
Ensuring the survival of plants in the long term in drought and adverse soil conditions is the main task of soil aggregates - regardless of whether they are trees, shrubs, grasses, shrubs or ornamental plants.
GEFA is constantly developing new product solutions and continuously revising the existing product range. The well-known STOCKOSORB® water storage tank has been modified again and significantly improved.
The new STOCKOSORB® has particular advantages in terms of its water absorption capacity. Under practical conditions, a 50% increase in the water retention capacity under soil conditions could be achieved. In addition, the innovative water storage granulate has a higher cycle stability and thus a longer service life. Planners and executors can thus save water even more effectively and cost-effectively and bridge periods of drought.
There are also further advantages in use, for example when mixing into substrates. The new STOCKOSORB® is less sensitive to moisture, i.e. the risk of clumping is greatly minimized.

Scientifically proven benefits
Studies by the University of Göttingen, Institute for Forest Botany, confirm the many advantages of STOCKOSORB®.
The research structure:
- Soil: sandy soil in a 30 l container - Plants: Aleppo pine (Pinus halepensis) - Variants: sandy soil without STOCKOSORB® 3g / l - sandy soil with STOCKOSORB® 4g / l - 4 and 8 weeks of even watering, then no further watering - Climate: greenhouse 30 - 40% humidity / 30 ° C - climatic chamber 30% humidity / 27 ° C
research results
In terms of water capacity and availability, the sandy soil resembles a clay soil after treatment with STOCKOSORB®. Evaporation from the soil is reduced by around 20% and the plant effectively has more water available and it suffers less from drought stress. The water stored in the ground can thus be used to the maximum for productive transpiration.
With STOCKOSORB® the soil stays moist longer and the plant biomass increases. The addition of STOCKOSORB® (4g / l sandy soil) leads to a three times higher growth in the shoot and a tripling of the root mass. (Sprout growth in cm, root mass g / DM.)
STOCKOSORB® acts like a soil colloid. When water is absorbed, the hydrogels swell and thus increase their volume. This reduces the density of the soil by 23.4%. When the soil begins to dry out, the hydrogels shrink again and form stable cavities. This loose structure of the soil, created by swelling and shrinking, is permanently retained. Due to the decreasing storage density, the soil treated with STOCKOSORB® is loosened and thus the rooting is facilitated.
The pore volume of the soil treated with STOCKOSORB® (3 g / l soil) increases by 40.5% compared to the untreated soil. The soil becomes looser and allows water to pass through better. If STOCKOSORB® has reached its maximum absorption capacity, no more water is stored and the excess water flows away. The combination of all these properties successfully prevents waterlogging in the root area. This low sensitivity to moisture is also an advantage when mixing into substrates, because it greatly reduces the risk of clumping.
In 2010 the University of Hohenheim, Stuttgart, examined the survival rate of lawn plants when used with and without STOCKOSORB®. The water storage granulate is scattered before sowing and then worked evenly into the vegetation layer from a depth of approx. 15 cm. This significantly increases the water storage capacity of the substrate. In the germination phase, there is a larger safety buffer for germination and the survival rate of the lawn plants increases significantly.
Global warming and climate change
Man-made global warming is advancing. The months of February, March, May and June 2015 were the warmest on record.
Heat records will continue to rise. The probability of extreme weather events due to very hot periods increases, as the entire temperature profile is now at a higher level.
The green industry must therefore think ahead. The soil should be able to store the last rainfall for as long as possible. With STOCKOSORB® the existing soil can be improved so that it can store the vital water in significantly higher quantities.
STOCKOSORB® Questions and answers
In connection with the effect and use of STOCKOSORB® and related soil additives, several questions arise time and again, which we answer briefly and concisely:
What is STOCKOSORB®?
STOCKOSORB® - water storage with potassium fertilizer effect (> 24% K²O total). It stores up to 300 times its own volume in water and makes it available to the plants; in use in landscaping and agriculture for over 20 years. Chemically: cross-linked homopolymer based on potassium.
What distinguishes STOCKOSORB® from other absorbers?
Usually the chemical composition. Often hydrogels are only made to store water but not to release it (e.g. in diapers). In addition, there are absorbers that are based on sodium, which salty the soil, only have a very limited effect.
Where does STOCKOSORB® make sense?
In principle for all plantings where it is about the water retention capacity of soils and Increasing substrates, bridging dry periods and improving growth successes.
Does the use of STOCKOSORB® save costs?
Yes, scientific studies and the Our customers' experiences have shown:
• Up to 60% reduction in the number of runners • prevents plant failures • reduces the use of fertilizer
How long does STOCKOSORB® work?
With full performance about 5 years. After that, the granules in the soil are demonstrably biodegraded.
Alginure granulate
Vigorous plant growth and a colorful world of flowers require vital soil life. Even slight disturbances of the sensitive soil structure impair the plant growth and increase the maintenance effort. Common causes are waterlogging, insufficient soil contact, drought or soil compaction.
With the primal power of seaweed
Our alginure products are based on the brown alga Ascophyllum nodosum. The brown algae native to the North Atlantic is characterized by its rich ingredients such as alginates, trace elements and secondary plant components (auxins). The alga is harvested sustainably and completely processed in the Tilco digestion. Thanks to the gentle process, the plant components are particularly protected and are released in a manner that is readily available to the plants. The result are alginure products that work biologically, physically and biochemically. The soil life is activated and the plant is vitalized. Alginates promote the formation of clay-humus complexes whereby the crumb structure is improved. The secondary plant components stimulate root and plant growth. The intensive sorption properties improve the utilization of irrigation and precipitation water.
Optimizes the soil structure and activates soil life
An effective bioactivator based on humic acid, with its 5% share, ensures fast and, at the same time, long-term healthy plant growth. The product component can be easily absorbed by the root, the carbon content promotes beneficial ones Soil organisms. In addition, the humic acids are able to bind salts and pollutants.
Mineral plus for soil and plants
The polyuronic acid / alginates contained in the Alginure Soil Granulate 1 combine with the soil particles to form clay-humus complexes. This increases the nutrient availability and storage power as well as the water and air capacity of the soil. The resulting crumbly structure optimizes the development of the root ball and plant growth.
Increased storage capacity by adding Alginure soil granulate 1
The figure shows the influence of Alginure Soil Granulate 1 on the water storage capacity of a normal topsoil. Without Alginure Soil Granulate 1, water flows off directly (left) without being available to the plant in the root area. Alginure soil granulate 1 increases the storage capacity through a pronounced gel formation. This means that water and nutrients are available for the plant.
Alginure soil granulate 1 is an organic mineral potassium fertilizer based on brown algae with magnesium and sulfur.

Novihum permanent humus
With NOVIHUM® as a substrate additive, you give your trees the decisive edge for optimal, permanent growth results. NOVIHUM® supports healthy root development, makes your trees resistant to environmental factors, improves water use efficiency and provides an effective nitrogen source.
NOVIHUM® is a unique soil and substrate improver, which in its structure is equivalent to a natural permanent humus and causes an increase in soil and substrate fertility. According to a patented process that was developed at the TU Dresden, the natural raw material lignite, which has a high concentration of humic substances, is enriched with nitrogen.
The nitrogen that is now bound in the structure of the humic substances becomes dependent from its binding form, released over a longer period of time and made available to plants. The particularly favorable C / N ratio of 11 ensures that the stable organic substance works, which benefits soil fertility and substrate quality. NOVIHUM® consists of over 80% humic substances (humic acids, fulvic acids and humins), which improve plant development and vitality in the soil and root space. Freedom from fungi, weed seeds, pathogens, pollutants and constant quality are features that distinguish NOVIHUM®.
The effects of the permanent humus granulate NOVIHUM® are particularly interesting with regard to the problems of urban trees and plantings in urban areas with their difficult location conditions and can make a decisive contribution to healthy development. So permanent humus-like humic substances are able to increase the drought stress resistance and water use efficiency of plants and thus maintain vitality even under adverse conditions.
The phytohormone-like mode of action of humic substances promotes the development of the root system of plants, which has an overall positive effect on tree health and its development. The functional groups of humic substances prevent nutrients from being leached out, as nutrients accumulate on them and are released to the roots when required be.
Mode of action NOVIHUM®
NOVIHUM® corresponds in its properties to high-quality, natural permanent humus. As a slowly flowing nitrogen source, NOVIHUM® increases the permanent humus content and optimizes the starting conditions for optimal plant growth. At the same time, NOVIHUM® initiates a higher humus accumulation rate, especially on weak, sandy locations. As a result of the permanently increased productivity of the plants, the permanent humus content in the soil increased by NOVIHUM® remains in the long term received.

PERLHUMUS® und POWHUMUS
Humic substances are almost all-rounders among the soil additives and take on much more than just the task of a pure nutrient store. PERLHUMUS® and POWHUMUS are among the most effective and high-quality products in this area. PERLHUMUS® is the specialist with long-term effects. With POWHUMUS, successes can be achieved in a short time. Combinations with mycorrhiza and STOCKOSORB® have proven particularly useful in tree renovation.
Origin
Humic substances can be found in all soils and bodies of water. They arise from plant breakdown products and can be broken down into humic, humic acid, fulvic acid and ulminic acid by extraction. Their salts are called humates, fulvates and ulmates. As the main fraction, humic acid forms the biological center of humus.
Basically, the use of humic substances has an extremely positive effect on our soils. Problems such as salinization, calcification, decrease in soil fertility, the destruction of useful microorganisms, increased erosion, the increased occurrence of plant diseases and the accumulation of toxic residues in the soil can be minimized by PERLHUMUS® and POWHUMUS.
The high-performance PERLHUMUS® and the water-soluble concentrate POWHUMUS are made from leonardite, a soft brown coal with up to 85% humic acid. The contained humic acids are hardly broken down further in the soil. This ensures a permanent humus supply. This can also be used to guide roots in certain directions and even in depth.

Compo Baumkraft® tree cure for trees
The living conditions in the city are often not optimal for the growth of trees: sealed areas restrict the water supply, underground pipes restrict the growth of roots. Such stressed and weakened trees are susceptible to diseases and pests. As a result of the reduced vitality, the foliage on the crown is thinning, twigs and branches die off.
Solution:
In addition to a regulated water supply, fertilization is a decisive factor in maintaining the desired functionality of the tree. COMPO Baumkraft® Volldünger ensures the need-based supply of nutrients. The high potash and magnesium content as well as the wide range of micronutrients promote vitality and vigor without causing mass growth.
Prevent salt damage
The road salts used in winter deteriorate the soil structure and the salt load on city trees increases. The soil silts up and lets in less air and water. Instead, sodium and chloride ions increasingly reach the leaves via the roots, where, depending on their concentration, they can cause severe damage: leaf litter, late budding, necrosis. A need-based supply of nutrients in advance strengthens the resistance of the trees. An impending salt shock is countered with fertilization in spring (if possible immediately after the dew phase): The Baumkraft® nutrients can occupy the soil colloids in good time and be absorbed by the roots instead of the salt ions. The tree remains healthy and resilient.
Advantages:
- Supply of essential nutrients - Improvement of the soil structure - Activation of root growth - Optimization of the water balance - Increasing the stress tolerance - Exchange of damage
COMPO Baumkraft fluid®
COMPO Baumkraft fluid® is a liquid special fertilizer for trees with important main and trace nutrients. The nutrients are in dissolved form and can be immediately absorbed by the roots.
