2  The aim of research  Theory ◦ Nitrogen ◦ Fertilizers- return of nitrogen into the soil  Research – laboratory work  Results  Discussion  Conclusion  Future plans  Bibliography illustrative image

3  to investigate the necessity of nitrogen for the plant growth  to compare the effect of various fertilizer concentrations (NH 4 NO 3 ) on plant growth Author of photo: Lucia Ličková

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

5  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 – Nitrogen cycle in nature

7 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 Pict.2: Scheme of ammonium production - Haber₋Bosch method

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

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

11 Pict.7: Preparation of NH 4 NO 3 by titration Pict.9: Checking pH Pict.10: NH 4 NO 3 Pict.8: Preparation of NH 4 NO 3 by mixing NH 3 and HNO 3 Author of photos: Klaudia Kvaková

12  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 Author of photo: Klaudia Kvaková

23  growing in solutions ◦ unsuccessful ◦ inhalation through a straw- deficient ◦ decay process  growing in 3 substrates ◦ sand, perlite, soil – do not contain nitrogen ◦ fertilization with various concentration of NH 4 NO 3 plants planted in perlite grow better  4 % solution ◦ high content of NH 4 NO 3  1 % solution ◦ ideal content of NH 4 NO 3 for healthy growth  different conditions for growing

24  NH 4 NO 3 ◦ high content of nitrogen ◦ in the right concentration – suitable for fertilization  healthy growth of plants, higher yield crops

25  to increase the number of measurements  to grow plants under the same conditions (temperature, humidity)

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

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.
