A researcher is conducting a study using a Randomized Block Design with 4 blocks to test the effectiveness of 3 different fertilizers (A, B, C) on plant growth. To ensure each fertilizer is tested equally across the blocks, how many total experimental plots are required, and what is the primary purpose of the blocks?
