1. A method comprising: storing, in a database accessible by an agricultural management information system, a environmental compliance requirement; receiving, by one or more modules in an agricultural management information system, first data associated with an impact on groundwater pollution or surface water pollution, the impact on the groundwater pollution or the surface water pollution resulting from a production of an agricultural product, the first data being received from a single sampling location, the first received data including a first data record from a first custodian device located at a first location in the series of agricultural operations at which the first custodian device read a first code that pairs a data type with the first location, the first data record pairing a first value that quantifies the data type with the first code that pairs the data type with the first location; receiving, by the one or more modules in the agricultural management information system, second data associated with the impact on the groundwater pollution or surface water pollution, the second data being received from a plurality of sampling locations, the second received data including a second data record from a second custodian device located at a second location in the plurality of locations in the series of agricultural operations at which the second custodian device read a second code that pairs the data type with the second location, the second data record pairing a second value that quantifies the data type with the second code that pairs the data type with the second location; generating, by the one or more modules in the agricultural management information system, an aggregate result for the data type based on the first or second data and a determination or condition that an aggregated set of data records that includes the first and second data records is sufficient for automatic generation of a report about the data type; generating and including in the report, by the one or more modules in the agricultural management information system, comparative data using the aggregate result and at least some of the first or second data, and indicating in the report whether the data type that is paired with the first and second locations by the first and second codes meets or does not meet the aggregate result for the data type; and causing a user device to receive and display the generated report about the data type, the user device being distinct from the first and second custodian devices from which the first and second data records are collectively received.
