Agriculture actual harvest record , fertiliser application and ipm application

i have been following up on this issue and now am stuck while trying to implement this on actual farm.

Based on this, there are instances that we do produce, in this case Spinach from seeds or Spinach from seedlings

Are this going to be recorded as different crops such that they will be selected separately while creating a crop cycle
Under crop, we have produced items, but the produce varies different based of different factors, so how can i record actual harvest for each crop cycle
How can i view all activities and IPM of a particular crop cycle?

Lastly, how does the carrot produced update the inventory in the warehouse? and were it to be taken to manufacturing what would be the procedure?
