Identifying management zones in agricultural fields and generating planting plans for the zones

A method comprising:

• using instructions programmed in a computer system comprising one or more processors and computer memory:
• determining two planting plans based on, at least in part, planting characteristics data received for an agricultural field and a plurality of management zone delineation options defined for the agricultural field;
• wherein each of the two planting plans specifies different planting recommendations for the agricultural field;
• using presentation instructions, generating and causing displaying, on a computing device, a first graphical representation of the two planting plans, and generating and causing displaying on the computing device an interactive object that is programmed to receive first input specifying a relative importance ratio between the two planting plans for determining a new planting plan for the agricultural field;
• using the instructions, receiving, via the interactive object, second input specifying a particular relative importance ratio between the two planting plans for determining the new planting plan for the agricultural field;
• using the instructions programmed in the computer system, determining the new planting plan based on the particular relative importance ratio and the two planting plans;
• wherein the new planting plan specifies new planting recommendations for the agricultural field;
• using the presentation instructions, generating and causing displaying, on the computer device, a second graphical representation of the new planting plan.
