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

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

BIBLIOGRAPHY

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.
