13. HYDROGELS INPUBLIC SPACE PLANTING www.hydrogel.pl

14. II. HYDROGELS INPUBLIC SPACE PLANTING We use hydrogel in pure form for planting of trees and bushes www.hydrogel.pl

15. II. HYDROGELS INPUBLIC SPACE PLANTING Advantages: guarantees greater survival rate of the planted trees www.hydrogel.pl

16. II. HYDROGELS INPUBLIC SPACE PLANTING The cycle of young tree/bush planting • we enrich 2/3 of soil with hydrogel • - hydrogel is mixed with dry soil www.hydrogel.pl

17. II. HYDROGELS INPUBLIC SPACE PLANTING The cycle of young tree/bush planting we enrich soil taking into account the root system growth we cover the root system with hydrogel www.hydrogel.pl

18. II. HYDROGELS INPUBLIC SPACE PLANTING The planting cycle of young tree or shrub add remaining soil filling in the whole. water them intensely to get muddy slime www.hydrogel.pl

19. II. HYDROGELS INPUBLIC SPACE PLANTING The planting cycle of young tree or shrub During planting trees the soil mixed with hydrogelcannot be directly under the root system of a plant because we can cut water off from roots. www.hydrogel.pl

20. II. HYDROGELS INPUBLIC SPACE PLANTING Protection of the bare root system Providing water to the bare root systems of seedlings. The process of covering roots with hydrogel allows to eliminate water stress caused by lack of H2O during transport of seedlingsfrom nurseries to the dedicated places. www.hydrogel.pl

21. HYDROGELS IN URBAN GREENERY www.hydrogel.pl

22. III. HYDROGELS IN URBAN GREENERY In urban greenery we use hydrogel compound fertilizer www.hydrogel.pl

23. III. HYDROGELS IN URBAN GREENERY Thecomposition of hydrogelcompundfertilizers: • 20% of purehydrogel; • 30% of granulatedfertilizer; • 50% of structure-forming mineral rock additives; Nutrients release lasts from 1 up tp 6 months! www.hydrogel.pl

24. III. HYDROGELS IN URBAN GREENERY Apllication: • flower beds • lawns • pots • flower stands • flower towers • urbanpots • hangingplanters • for lamps www.hydrogel.pl

25. III. HYDROGELS IN URBAN GREENERY Dosage: 5 kg of compound fertilizer per 1 m3 of soil 5 kg of compound fertilizer per 1L of soil www.hydrogel.pl

26. III. HYDROGELS IN URBAN GREENERY Dosage: Flower beds and lawns in the city: 2 Mix 100g up to 150g per 1m with the soil at a depth of 25cm www.hydrogel.pl

29. HYDROGEL SOIL INJECTION www.hydrogel.pl

30. IV. Hydrogel soil injection Problem: - withering of natural monuments; - withering of trees in the city; - withering of roadsidetrees; - withering of shrubs; www.hydrogel.pl

31. IV. Hydrogel soil injection Causes of withering trees in cities : • Relating to treetops • (treetop growth is limited, emissions, drying out); • refers to thetrunk • (exposure to collision and vandalism); • refers to theroots www.hydrogel.pl

32. IV. Hydrogel soil injection The causes of withering trees in cities : • soil density ( lack of root system growth) • soilpH, soilsalinity • water shortages, lack of capillary soaking, lack of rainwater • soilstructure • soiltemperature • soilaeration • nutrientdeficit • soilcontamination • infrastructure development www.hydrogel.pl

33. IV. Hydrogel soil injection Conclusions: Researchers agree that for trees in cities the most threatening are the causes which influence the roots growth (prof. MarekKosmala, 2001) The worst enemy of roadside trees is completely degraded soil in the cities and also water deficits. www.hydrogel.pl

34. IV. Hydrogel soil injection Solution: Hydrogels: • - storewaterwithnutirents • - reduce soil density through its shrinkage • increasesoilaerial • enrichsoilwithnutrients www.hydrogel.pl

35. IV. Hydrogel soil injection Solution: An innovative method of saving full-grown trees by pumping under proper pressure to the depth of 80-100cm diluted hydrogel around the root system. To improve the conditions of trees we enrich hydrogelwith fertilizers. www.hydrogel.pl

36. IV. Hydrogel soil injection The hydrated hydrogelis pumped into soil every 50cm around the root system. www.hydrogel.pl

37. IV. Hydrogel soil injection Stage I Details study of dendrochronology, drawing up an inventory and creating dendrological opinions www.hydrogel.pl

MarekSiewniak • Avenue of chestnut trees in Pabianice • Dendrochronology research conducted by: • Prof. dr hab. Leszek B. Orlikowski www.hydrogel.pl

44. V. Summary Hydrogele Increase water retention by absorbing it in the amount excessing 250-300 times its own weight by increasing the water capacity of soil and substrates they limit the effects of water shortage they improve heavy soil structure by reducing their density they improve light soil structure by preventing them from water and wind erosion they reduce eluviation of nutrients they are durable and active in the soil within 3-5 years they stimulate root system growth they speed up the plants growth up by reducing the loss of them Thanks to them you can save money and time www.hydrogel.pl
