Soil Wetter is a water retainer that, when incorporated into a soil or a substrate, absorbs and retains large quantities of water and nutrients.Unlike most products that become hydrated, Soil Wetter has the property of easily releasing the absorbed water and nutrients, thereby allowing the plant to have water and nutrients available at will as a function of the absorption – release cycles.
• Increases the Water Holding Capacity of soils for several years.
• Irrigation frequency may be reduced by 50%.
• Limits losses of water and nutrient due to leaching
• Reduces evaporation from the soil
• Improves the physical properties of compact soils through aeration
• Enhances plant growth. Water and nutrients are continuously available in the root zone for optimal absorption by
• Protects the environment against drought and groundwater pollution
HOW IT WORKS
The polymer consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by
cross-linking agents, thus forming a network. When water comes into contact with one of these chains, it is drawn into the
molecule by osmosis. Water rapidly migrates into the interior of the polymer network where it is stored. As the soil dries
out, the polymer releases up to 95% of the absorbed water into the
• The more the polymer is cross-linked, the tighter the network. Thus absorption capacity decreases but the polymer
remains more stable over time.
• Conversely, the less cross-linking there is, the looser the network. Absorption volume increases, but stability is
Soil wetter is offered in different particle sizes of which the absorption and release capacities vary depending on the
conditions in the soil environment.
An outstanding absorption capacity: In general, the finer the particle size of the polymer, the greater its absorption
capacity and speed.
A buffering effect on the availability of fertilizers: Soil wetter significantly reduces the leaching of fertilizers because they
are stored in the network. The fertilizers are available to plants for a longer time due to a delay effect on their release.
The influence of salts: The presence of electrolytes in the aqueous medium significantly diminishes the absorption capacity
of soil wetter. This explains the fact that the water holding capacity of soil wetter in a substrate varies around 100-150 times
The wilting point is delayed: soil wetter makes it possible to increase the Water Holding Capacity of soils and to delay the
wilting point. A sandy soil treated with 2 grams of soil wetter per kg of soil holds water twice as long as untreated soil.
FORESTRY AND TREE CROPS, COFFEE, TEA, FRUIT TREES
Soil wetter is effective in the planting of trees and bushes. It makes it possible to reduce the mortality rate due to
transplanting shock and to enhance root development and therefore bring about rapid growth and production. Dig a hole
about three times the volume of the root system.
• Mix 50 g of Soil Wetter with 1 bucket of soil.
• The polymer must be evenly mixed into the excavated soil. A small amount of untreated soil must be set aside.
• Place the root ball of the plant at the bottom of the hole and fill in the hole with the treated soil. Make sure that
the product is distributed evenly around the roots. Then cover the surface with 5cm of untreated soil to prevent
degradation of the polymer by ultraviolet rays and stagnation of water on the surface.
• Be especially careful not to put unmixed dry product at the bottom of the hole. After hydration, the product would
destabilise the plant.
LAWNS & SOD
Water retainers are very easily used throughout the growth cycle of lawns and sod. They ensure good germination, faster
root development, regular and even growth of lawns. The rooting of sod is also faster. They are widely used in landscaping
for golf courses and grass in parks and gardens.
• Work, break up, and level the soil to be planted with grass.
• Spread Soil wetter at a rate of 20-50g\m2 on the surface of the soil. The polymer may be broadcast or applied with a
fertiliser spreader for a more even distribution.
• Work Soil wetter into the soil to a maximum depth of 10cm. This can be done by hand with a spade or mechanically
with a disk plow or a rototiller.
• Seed the lawn or lay the sod. Roll the soil to compact it.
• Use fertilisers if needed.
BARE ROOT TRANSPLANTS (FLOWERS,VEGETABLES AND POT TRANSPLANTS AND DIRECT SEEDED CROPS)
Soil wetter can be used for root dipping in order to prevent the desiccation of the roots of seedlings during transplanting
or transport over a long distance.
The dressing is prepared as follows:
• Mix 1 kg of Soil wetter in 150-200 litres(1 Drum) of water. Amounts vary depending on the salinity of the water.
• Slowly pour in the product while stirring the water to obtain a dressing without dumping of particles.
• Let the dressing stand for 15 minutes, the time needed for soil wetter to reach its maximum absorption. It is
important to obtain a dressing that will adhere completely to the roots. The longer the maturation time, the thicker
the dressing will be and the better it will adhere to the roots.
• A water soluble nematicide and / or fungicide may also be added to the preparation to protect plants against
nematode and fungal attacks.
Another method would be to directly incorporate Soil Wetter into the planting hole.For annual crops with shallow root
system incorporate 5-10g SoilWetter into the planting hole and mix thoroughly with soil while for larger annual crops 15-
20g should be incorporated. For semi Perennial crops use 25-30g per planting holeWhikle for crops planted in furrows such
as Potato, Sugar cane incorporate 5g Soil wetter per metre of furrow.
Mix 5 -10g Soil Wetter per m2 of nursery bed to ensure better seedling germination and growth.
For potted plants add 2-5g Soil Wetter per pot and mix thoroughly with the media.
MIXING WITH FERTILIZERS
To reduce leaching of nutrients in the soil, Soil wetter may be mixed dry into fertilizer preparations. The behaviour of
plants fertilised with this mixture makes it possible to maintain or even increase yield while at the same time protecting the
environment from leaching. Manufacturers’ test results also show better root development of the plants.
Savings on the order of 15% to 30% are observed in the amount of fertilisers.
Soil wetter is commonly used for colouring the water in glass containers. Soil wetter in granules is allowed to expand in
coloured solutions. The hydrogel is placed in glass containers in which cut flowers may be placed. 5g per litre of water.
TRANSPORTING CUT FLOWERS
Soil wetter in the form of hydrogel may be placed in sealed plastic pouches. Once frozen, the pouches are often used in
the transport of heat-sensitive plant products such as cut flowers. The hydrogel has excellent resistance to heat shock and
does not leak after thawing.
Soil wetter has also shown its effectiveness in large-scale farming, especially at the time of germination and development of
the root network due to good aeration of the soil. The storage of rainwater or irrigation water by Soil wetter delays the wilting
point and thus makes it possible for certain plants to begin to be well established while waiting for the water regime to
become adequate. Soil wetter ensures a good population and an even growth of plants even in very permeable soils.
For example, in the farming of rain-fed sugar cane, significant increases in yield of approximately 25% are observed.
• When planting a field, put Soil wetter in the furrows where the cane shoots are placed.
• Soil wetter may be applied at the same time as a fertiliser.
• Cover the shoots with soil by earthing up.
Application of the dry or hydrated product:
• After hydration of the dry product, it becomes a transparent gel that is greatly expanded.
• When the product is mixed dry into a substrate, it is recommended that an empty space of a minimum of 15% be left in
containers. During hydration, the substrate could overflow its container.
• Dry products must not be placed under plugs. The plant could be destabilised after Soil wetter hydration.
• It is preferable to mix the dry product in an irrigated soil or substrate.
• On the other hand, hydrating the product in a non-irrigated soil is recommended so that it becomes active immediately.
• The higher the water temperature, the faster the absorption of water by Soil wetter.
• All the products in the Soil wetter line have a high absorption capacity. If the product is spilled, be sure not to rinse it
with water. The ground would become extremely slippery. Shovel or vacuum it up.
• To clean equipment, blow off the powder traces with compresses air.
• Avoid contact with eyes and skin (use of gloves and goggles is recommended).
The polymer is sensitive to the action of ultraviolet rays that, by breaking bonds, degrade the polymer into oligomers
(molecules of much smaller size). It thus becomes much more sensitive to the aerobic and anaerobic processes of
Soil wetter therefore degrades naturally in soils (up to 10% – 15% per year) in CO2, H2O and nitrogen compounds.
The polymer is much too voluminous to be absorbed into the tissues and cells of plants. Its potential to bioaccumulate is
The period of effectiveness of Soil wetter in the field ranges from one to five years depending on particle size and agroclimatic
