If you google you can find some related information with examples, here is one.

I was trying to figure your design from you description in your other post but I could not.  Can you show a "picture" or other schematic of you design.  One thing I could not figure from you description was which factor(s) was not randomized.

Hi

 

I have attached the design. There are four level of P nutrients (label A to D), four levels of N nutrients (0 to 3), two different crop rotations and two blocks. Therefore, I think the design should be a split-split block. All factor except the block are fixed.
