After specifying the crop plan header, groups and products, view the Summary details before sending the proposal to the grower.  

On any crop plan, scroll down to the bottom of the plan to view the Summary tabs:

Overview, which shows the total items purchased, the discounts applied and Split details in terms of which split partners owns what.  

The Splits tab, which not only shows the split partner details, but describes the Split Definitions that prescribe the split details.  

The Products tab, which shows how much of each product is specified to be delivered as part of the plan.  

A likely next step is to send the proposal to the grower.
