An image of soil is received from a camera and is associated with location data from a GPS sensor. The image is divided into sub-images, which are processed using a first ML model. The first ML model is trained to classify images into either soil or residue. The sub-images classified as soil are processed using a second ML model, which is trained to classify images into either high organic matter or low organic matter. The second ML model is trained on image data where a mean and standard deviation of RGB data of the image data provides an indication of an amount of organic matter in the imaged soil. An organic matter map is then generated.
