Abstract: Disclosed herein is a system and methods for leaf detection and extraction. The extracted leaf may be used for leaf water potential analysis. In some embodiments, the method comprises identifying the leaf from a point cloud based on an image, determining a pose of the leaf based on the point cloud, and cutting and storing the leaf based on the pose of the leaf.

Abstract: Apparatus and methods for determining soil moisture. An apparatus includes a mobile platform to traverse an agricultural field, a sensor physically coupled to the mobile platform, the sensor to make one or more soil apparent electrical conductivity measurements, and a control system mounted on the chassis and communicatively coupled to the sensor. A method includes navigating an agricultural field with a mobile platform, generating a real-time position and orientation for the mobile platform, performing one or more soil apparent electrical conductivity measurements from a sensor physically coupled to the mobile platform, synchronizing the one or more soil apparent electrical conductivity measurements with the real-time position, geospatial mapping and autonomously logging the one or more soil apparent electrical conductivity measurements, and processing each of the one or more soil apparent electrical conductivity measurements to generate a soil moisture value.
