1. Analyzing the differences in the properties (Bulk Density and Porosity) of the 12 substrates used in the Growth cylinders experiment. Made by: Lynn, Susu and Machiel Instructors: Andronikos Mauromoustakos Athanasios Gertsis

2. Introduction What did we analyze? Why did we do this analyzes? How did we get the bulk density and porosity data?

3. Substrates data SUBSTRATE BDPORO. PP0.120.96 PPZ0.410.85 PPV0.120.95 PPV0.20.93 PPZ0.280.89 PP0.120.95 MS1.20.55 MSZ1.060.6 MSV0.770.71 MSV0.840.68 MSZ0.720.73 MS1.180.56 SUBSTRATE BDPORO.

5. Distribution of bulk density and porosity

6. Correlation Multivariate Correlations BD1.0000-0.9998 Porosity -0.99981.0000

7. Is BD a function of porosity?! Yes, it is!

9. One way analysis of BD by substrate

10. One way analysis of porosity by substrate

11. Analyzing the base: Peat +Perlite

12. Analyzing the base: “Manure + Sand”

13. Analyzing the base: Sand

14. Analyzing the base: Soil

15. Conclusions BD is a function of the porosity. So this means that when the BD is high the porosity is low and when the porosity is high BD is low. When you plot this function you get a linear line.

16. Affects of vermiculite Vermiculite improves the porosity in soils with “sandy base”. Vermiculite improves the BD in soils with a “peat and perlite base”. Vermiculite improves the porosity in soils with a “manure and sand base” Vermiculite improves the porosity in soils with a “ clay loam base”

17. Affects of Zeolite Zeolite improves the porosity in soils with “sandy base”. Zeolite improves the BD in soils with a “peat and perlite base”. Zeolite improves the porosity in soils with a “manure and sand base” Zeolite improves the porosity in soils with a “ clay loam base”

18. Which group is the best? We think the substrates with the are the best, because this substrates doesn't have great significant difference. “Soil base’s”
