A system for estimating a crop characteristic comprises a database, a plant growth model correlator, and a crop characteristic estimator. The database includes plant growth models for a plurality of fields. The plant growth model correlator is communicatively coupled with the database. The plant growth model correlator is configured for determining at least one harvested field with a first plant growth model which correlates with a second plant growth model for at least a portion of an unharvested field. The crop characteristic estimator is configured for estimating a crop characteristic for the unharvested field based on actual crop characteristic data obtained from the at least one harvested field.
