Abstract: A computer implemented method for generating digital models of relative crop yield based on nitrate values in the soil is provided. In an embodiment, nitrate measurements from soil during a particular portion of a crop's development and corresponding crop yields are received by an agricultural intelligence computing system. Based, at least in part, on the nitrate measurements and corresponding crop yields, the system determines maximum yields for each location of a plurality of locations. The system then converts each crop yield value into a relative crop yield by dividing the crop yield value by the maximum crop yield for the location. Using the relative crop yields and the corresponding nitrate values in the soil, the system generates a digital model of relative crop yield as a function of nitrate in the soil during the particular portion of the crop's development. When the system receives nitrate measurements from soil in a particular field during the particular portion of a crop's development, the system computes a relative yield value for the particular field using the model of relative crop yield.

Abstract: A method for determining national crop yields during a growing season is accomplished using a server computer system that receives observed agricultural data records for a specific geo-location at a specific time. The server calculates weather index values from the agricultural data records that represent crop stress on plants. Geo-specific weather indices are generated from the weather index values, which then are aggregated to generate aggregated weather index data series. Representative features are selected from each aggregated weather index data series to create a covariate matrix for each geographic area. Crop yield for the geographic area is calculated using a linear regression model based on the covariate matrix for the specific geographic area. The server determines a national crop yield for the specific year as a sum of the crop yields for the specific geographic areas nationally adjusted using national yield adjustment instructions.

Abstract: A method for determining national crop yields during the growing season using regional agricultural data is provided. In an embodiment, determining national crop yields during the growing season may be accomplished using a server computer system that receives, via a network, agricultural data records that are used to forecast a national crop yield for a particular year. Within the server computer system an agricultural time series module receives one or more agricultural data records that represent a type of covariate data value related to plants at a specific geo-location at a specific time. The agricultural time series module then aggregates the agricultural data records to create one or more geo-specific time series that represent a specific geo-location over a specified time. The agricultural time series module creates one or more aggregated time series that represent geographic areas from a subset of the one or more geo-specific time series. A crop yield estimating module selects a representative feature from the one or more aggregated time series and creates a covariate matrix for each specific geographic area in computer memory of the server computer system. The crop yield estimating module determines a specific state crop yield for a specific year by using a linear regression module to calculate the specific state crop yield from the covariate matrix that represents the specific state for that specific year. The crop estimation module determines a national crop yield for the specific year by using the distribution generation module to calculate the national crop yield for a specific year from the sum of the specific state crop yields for the specific year nationally adjusted using a national yield adjustment module.

Abstract: A method for determining national crop yields during the growing season may be accomplished using a server computer system that receives, via a network, agricultural data records that are used to forecast a national crop yield for a particular year. Within the server computer system weather index calculation instructions receive one or more agricultural data records that represent observed agricultural data points for a specific geo-location at a specific time. The observed agricultural data points include, but are not limited to, observed temperature records, soil moisture records, and precipitation records for the specific geo-location. The weather index calculation instructions then calculate one or more weather index values from the one or more agricultural data records. Weather index values represent crop stress that may affect the crop yield of particular plants. The weather index values are then compiled into one or more geo-specific weather indices for one or more geo-locations over a specified period of time. Each of the geo-specific weather indices may contain weather index values representing various types of stress events on crop including, but not limited to, flood stress, drought stress, early drought stress, daytime heat stress, and nighttime heat stress. Within the server computer system, weather indices aggregation instructions aggregate the one or more geo-specific weather indices to create one or more aggregated weather index data series, where each aggregated weather index data series contains weather index values for a specific calculated weather index for one or more specific geo-locations. Each weather index data series represents a specific geographic area from a subset of the one or more geo-specific weather indices. Crop yield estimating instructions, in the server computer system, then select representative features from each aggregated weather index data series within each of the one or more aggregated weather index data series. The crop yield estimating instructions then creates a covariate matrix for each specific geographic area in computer memory of the server computer system. The covariate matrix contains the representative features selected from the one or more aggregate weather index data series. The crop yield for the specific geographic area for the specific year is calculated using linear regression instructions to calculate the specific geographic area crop yield from the covariate matrix that represents the specific geographic area for that specific year. The parameters of the linear regression instructions include regression parameters that are calculated using distribution generation instructions and an error term that is calculated using the distribution generation instructions where a mean parameter for the error term is zero and the variance parameter is a geographic area specific bias coefficient. After determining crop yields for the specific geographic area representing the one or more aggregated weather index data series, the crop estimating instructions determine a national crop yield for the specific year by using the distribution generation instructions to calculate the national crop yield for a specific year from the sum of the crop yields for the specific geographic areas for the specific year nationally adjusted using national yield adjustment instructions. In an embodiment, the crop yield may refer to a specific crop yield such as corn yield.

Abstract: A method for predicting field specific crop yield recommendations for a field may be accomplished using a server computer system that is configured and programmed to receive over a digital communication network, electronic digital data representing agricultural data records, including remotely sensed spectral property of plant records and soil moisture records. Using digitally programmed data record aggregation instructions, the computer system is programmed to receive digital data representing including remotely sensed spectral property of plant records and soil moisture records. Using the digitally programmed data record aggregation instructions, the computer system is programmed to aggregate the one or more digital agricultural records to create and store, in computer memory, one or more geo-specific time series over a specified time. Using the digitally programmed data record aggregation instructions, the computer system is programmed to select one or more representative features from the one or more geo-specific time series and create, for each specific geographic area, a covariate matrix in computer memory comprising the representative features selected from the one or more geo-specific time series. Using mixture linear regression instructions, the computer system is programmed to assign a probability value to a component group in a set of parameter component groups, where each component group within the set of parameter component groups includes one or more regression coefficients calculated from a probability distribution and an error term calculated from a probability distribution. Using distribution generation instructions, the computer system is programmed to generate the probability distributions used to determine the one or more regression coefficients and the error term, the probability distribution used to generate the error term is defined with a mean parameter set at zero and a variance parameter set to a field specific bias coefficient.
