Hello all R listers, I'm struggling to select an appropriate statistical method for my data set. I have collected soil moisture measurements every hour for 2 years. There are 75 sensors taking these automated measurements, spread evenly across 4 treatments and a control. I'm not interested in being able to predict soil future soil moisture trends, but rather in knowing whether the treatment affected soil moisture response overall. In particular, it would be interesting to inspect treatment related response within defined periods. For example, a visual inspection of my data suggests that soil moisture is equivalent across treatments during wet winter months, but during the dry summer months, a treatment effect appears.
Any help on this topic would be very appreciated. I've looked far and wide through academic literature for similar experimental designs, but have not had any success as yet.
