Precision crop production-function models

A non-transitory computer-readable storage medium storing a plurality of instructions executable by one or more processors, the plurality of instructions that, when executed by the one or more processors, cause the one or more processors to:

• receive nutrient data and yield data for a plurality of plants, the nutrient data including concentration levels of one or more nutrient elements in plant tissues;
• categorize the plurality of plants into a plurality of yield categories based on the yield data;
• for each yield category of the plurality of yield categories:
• analyze the nutrient data and the yield data for plants in the yield category to determine a relationship between a plant yield and a nutrient concentration level for each nutrient element of the one or more nutrient elements;
• and
• for each yield category of the plurality of yield categories:
• applying fertilizers to the plants in the yield category, the applied fertilizers having a nutrient level for each nutrient element of the one or more nutrient elements, and the nutrient level determined using the determined relationship between the plant yield and the nutrient concentration level for each nutrient element of the one or more nutrient elements for improved yields.

A system comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium including instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including:
• receiving nutrient data and yield data for a plurality of plants, the nutrient data including concentration levels of one or more nutrient elements in plant tissues;
• categorizing the plurality of plants into a plurality of yield categories based on the yield data;
• for each yield category of the plurality of yield categories:
• analyzing the nutrient data and the yield data for plants in the yield category to determine a relationship between a plant yield and a nutrient concentration level for each nutrient element of the one or more nutrient elements;
• and
• for each yield category of the plurality of yield categories:
• applying fertilizers to the plants in the yield category, the applied fertilizers having a nutrient level for each nutrient element of the one or more nutrient elements, and the nutrient level determined using the determined relationship between the plant yield and the nutrient concentration level for each nutrient element of the one or more nutrient elements for improved yields.
