Bush Snake Bean
From the result, we can conclude that different type of soil will affect the growth and germination of the plant. It's also will affect another plant too. Based on the result also, there are 2types of soil that didn't germinated any plant it is soil A and soil E. this is because the plant did not suitable to growth in both soil conditions. other than that, the plant in soil B,C, and D has suitable soil for all the plant to germinate.
From the graph, we can see that sulfur is higher in soil 1 and soil 5. While the nitrogen has the highest content in soil 3. But has the lowest content in soil 4. Phosphate has the highest content in soil 2. But the graph shown that the phosphate content is not obvious like sulfur and nitrogen.

Potted plants B,
C, D have nodules. But plants in
pot C has more nodules compared with other potted plants. This is because, under
nitrogen-limiting conditions, capable plants form a symbiotic relationship with
a host-specific strain of bacteria known as rhizobia. Soil type C containing more nitrates
than other soil types. Nodulation occurs when plants need additional
nitrogen. Beans send flavonoids into the soil through their root systems.
Rhizobia bacteria in the soil sense the flavonoids and send a signal called LCO
back to the plant. The plant responds with root hair curling where the Rhizobia
enter the plant and nodules are formed around them. Brown/Green colour of the
nodules do not fix Nitrogen for the plant.
