Abstract

Some embodiments of the present invention automatically measure the impact of natural conditions and/or deliberate interventions on crop yields. Other embodiments automatically predict the impact of natural conditions and/or deliberate interventions on crop yields. By eliminating the need for human intervention, judgment, or discretion from the processes of measuring and predicting impact on yield, embodiments of the present invention enable such measurements and predictions to be made significantly more accurately, quickly, and inexpensively than has been possible with preexisting techniques.
