I received the chemical analysis for the soil sent to A&L Labs. For the Control group, the readings looked similar to the original baseline, showing virtually no change in the elemental contents of the soil. However, for the Experimental group, there was an increase in levels of these nutrients such as N, K, Mg, and Ca. When comparing within the 2 cycles, the experimental group generally shows higher amounts of nutrient content than the control group and there is a more profound difference in Calcium, and earthworm castings application may play a role in that. My next step will be to do a paired t test using the within cycles values to see if the differences are significant. I have attached the graphs here for reference.
