Hello! i have conducted a greenhouse experiment with 4 treatments arranged according to a RCBD, I had 4 blocks (replications) and each experimental unit was constituted by 10 pots. during the experiment I have analyzed the soil pH at different dates (4 different dates), on soil sampled every time from a different pot (not the same pot), therefore I think these should not be considered as repeated measures or not? The same experiment was conducted two times during two different seasons (Summer and Winter). Besides evaluating the treatment effect, I would like to compare the two seasons and also the different sampling dates. So I have a few questions: What will be the best procedure to use in this case? Is the GLM procedure adequate? How I should consider the season and the sampling dates? Can you please help me to build the sas program for this case?  Thanks in advance for your help. FD  ...
