A crop signaling method and machine-based crop recognition system and methods are disclosed to detect a unique optical crop signal selectively applied to crop plants, allowing automatic differentiation of crop plants from weeds and the automatic creation of a high spatial resolution crop and weed plant map, along with automated plant management tasks.

Robotic plant care systems and methods

An apparatus and system for monitoring plant leaves to determine plant water needs and an automated variable-rate irrigation management system which can implement precision irrigation by taking into account specific plant water status is presented. Single or networked sensor platforms have a suite of sensors including a leaf temperature sensor for measuring leaf temperatures over time; an air temperature sensor; a relative humidity sensor for measuring relative humidity surrounding a leaf; a wind speed sensor for measuring wind speed surrounding a leaf; and an ambient light sensor for measuring solar radiation on the leaf. One platform has diffuser dome, leaf retainer and wind barrier structures. The sensor platform may have a computer processor and programming for obtaining and recording sensor measurements and determining plant water status in response to sensor measurements. The system may have a central control computer and communications link for communications with the platforms.
