Abstract: Systems, methods, and/or processes for agricultural parameter determination are provided. One or more can include or use processing circuitry configured to: manage one or more land parcels for agricultural parameter optimization (such as soil organic carbon optimization); and determine one or more agricultural parameters of at least a portion of one land parcel (such as an alleyway between commodity crops) during a first time period without sampling the portion of the one land parcel. Systems, methods, and/or processes for increasing soil organic carbon are also provided.
