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

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

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)

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.
