Technical characteristics of Aquaholder
The product is in a liquid form with inhibited superabsorbent. The liquid form of the product is important to ensure a standard application in the seed treatment process. The Aquaholder formula allows the inhibition of the superabsorbent during the seed application process and its activation only after in the soil.
Application of Aquaholder on seeds
The product is designed to be applicable in currently used technology of batch seed treaters. The following video shows the process of Aquaholder application on the seeds.
Aquaholder has been developed to meet the needs of the seed industry and for its application in batch seed coaters. There are solutions on the market using different application methods of absorbents, but their absorption capacity is often negligible, the seed coating process must take place in a dry environment and the adhering efficiency of absorbent on seeds is too low. When applying absorbents onto seeds, a critical technological barrier must be taken into the account, and that is the use of an extremely hydrophilic active substance in a wet seed coating process. Pewas has eliminated this problem and inactivated the absorbent during the production process. It is subsequently activated and absorbs water only after the seeds sowing into the soil.
What seeds can work with Aquaholder ?
Aquaholder can be used for various types of field crops. The application of Aquaholder has been successfully tested on seeds of the most cultivated field crops: wheat, barley, corn, sorghum, soybeans, oilseed rape, sugar beet, sunflower.
As each crop has different moisture requirements, the dosage of Aquaholder slightly varies from crop to crop.
Soil types and Aquaholder
Aquaholder has been designed to support a crop production in soils with reduced water retention capacity (sandy soils) and in arid and semi-arid areas. However, arid and semi-arid areas are expanding also in regions that have not yet been characterized as dry. In addition, climate change causes more frequent and unpredictable drought waves. Therefore, Aquaholder is not only suitable for standard dry areas, but can also serve as an insurance against drought anywhere in the world. Aquaholder's goal is to contribute to the sustainability of primary agricultural production even in such areas where yields are declining due to climatic conditions.
Aquaholder treated seeds handling
Aquaholder has been developed to meet the seed handling standards and there are no other special requirements for seed handling. The seed treated with Aquaholder is handled like any other seed during the transport, storage and sowing.
Aquaholder coated seed meets the seed quality standards and the criteria required for sowing.
The content of Pewas' research activities also includes the implementation of potentially supporting substances into Aquaholder. Initial research shows that Aquaholder with an implemented stimulant could reach higher level of support than each of the applications alone. Nutrients, mycorrhizal fungi and biopesticides are potentially suitable for Aquaholder enrichments that could lead to the synergy effect with the absorbent and help to support the germination process of the plants.
