2. CONTENT • The aim of research • Theory • Nitrogen • Fertilizers- return of nitrogen into the soil • Research – laboratory work • Results • Discussion • Conclusion • Future plans • Bibliography illustrativeimage

3. THE AIM • to investigate the necessity of nitrogen for the plant growth • to compare the effect of various fertilizerconcentrations(NH4NO3) on plant growth Author of photo: Lucia Ličková

4. TASKS • Production of ammonium nitrate in two ways. • Germination of bean seeds. • Growing bean in fertilizer solution, blind sample (distilledwater). • Analysis of results. • Production of posters and presentations. Author of photo: Klaudia Kvaková

5. THEORY • Nitrogen • essential element for the life of living organisms • important part of proteins and nucleic acids • human body is not able to produce nitrogen • nitrogen is absorbed through plant roots and bacteria living nearby • plants convert nitrogen into inorganic compounds • result – increasing quality of yield crops containing nutrients Author of photo: Klaudia Kvaková

6. Pict.1 – Nitrogencycle in nature

7. THEORY/INTRODUCTION FERTILIZERS – return of nitrogen into the soil • organic fertilizers • synthetic fertilizers – nitrogen based fertilizers with ammonium • Haber-Bosch ammonium synthesis • production of ammonium nitrate • using titration of ammonium with nitric acid • based on determination of pH and adding ammonium or nitric acid

8. Haber-Bosch ammonium synthesis Pict.2: Scheme of ammonium production - Haber₋Boschmethod

9. Discussion with • Mgr. Martina Holečkova about Africa • Poverty • Houses without electricity • Schools without computers • Fertile soil in Rwanda, Kongo Pictures 3, 4: Discussion about life in Africa Author of photos: Klaudia Kvaková

10. Discussion with Dr. ŠimonBudzák Pictures 5,6: Lecture – effect of nitrogen on plants and importance of nitrogen based fertilizers Author of photos: Klaudia Kvaková

12. PROCEDURE OF WORK • Study of literature about bean cultivation • Laboratory preparation of fertilizers • Germination of bean seeds • Growing in solutions – unsuccessful • Growing in three types of substrates • Observation • Documentation • Processing • Results Pict. 21: Plants – water solutions Authorof photo: Klaudia Kvaková

23. DISCUSSION • growing in solutions • unsuccessful • inhalation through a straw- deficient • decay process • growingin 3 substrates • sand, perlite, soil – do not containnitrogen • fertilization with various concentration of NH4NO3 plants planted inperlite grow better • 4 % solution • high content ofNH4NO3 • 1 % solution • ideal content of NH4NO3 for healthy growth • different conditions for growing

24. CONCLUSION • NH4NO3 • high content of nitrogen • in the right concentration – suitable for fertilization • healthy growth of plants, higher yield crops

25. FUTURE PLANS • to increase the number of measurements • to grow plants under the same conditions (temperature, humidity)

26. CONTRIBUTIONS OF THE PROJECT • new skills, knowledge, experience • team work • working with literature • future use Pict. 22: Team work Author of photos: PaedDr. Jana Chlebušová

29. THANK YOU FOR YOUR ATTENTION!

30. Experience, skills and knowledge we achieved in this project, moved us forward. We learnt to share the duties in the team. We improved our work with literature and we managed to choose the important facts we would like to present in the project. We will be able to apply the experience and skills in the future study of science and humanities, in writing thesis or team work problem solving.
