The aim of research Theory
◦ Nitrogen◦ Fertilizers- return of nitrogen into the soil
Research – laboratory work Results Discussion Conclusion Future plans Bibliography
CONTENT
illustrative image
to investigate the necessity of nitrogen for the plant growth
to compare the effect of various fertilizer concentrations (NH4NO3) on plant growth
THE AIM
Author of photo: Lucia Ličková
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.
TASKS
Author of photo: Klaudia Kvaková
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
THEORY
Author of photo: Klaudia Kvaková
Pict.1 – Nitrogen cycle in nature
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
THEORY/INTRODUCTION
Haber-Bosch ammonium synthesis

PLANTS GROWING IN SAND
Author of photos: Lucia Ličková
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 NH4NO3
plants planted in perlite grow better 4 % solution
◦ high content of NH4NO3
1 % solution◦ ideal content of NH4NO3 for healthy growth
different conditions for growing
DISCUSSION
NH4NO3
◦ high content of nitrogen◦ in the right concentration – suitable for
fertilization healthy growth of plants, higher yield crops
CONCLUSION
to increase the number of measurements
to grow plants under the same conditions (temperature, humidity)
FUTURE PLANS
new skills, knowledge, experience team work working with literature future use

THANK YOU FOR YOUR ATTENTION!
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.
