The subject of the invention is a method for developing a computer tool that utilises learning in a feedforward neural network FNN for the remote diagnosis of chemical element content in plants. The method includes collecting a training dataset, consisting of hyperspectral data from cultivated fields and measurement data on element content in plant leaves. The hyperspectral data is normalised and converted into input vectors, after which the dataset is divided into a training set and a test set. The training of the FNN involves an input layer with 64 neurons, a hidden layer with 32 neurons, and an output layer with a single neuron performing a regression function. The network is trained to match the predicted element content values to actual measurement data. The trained network is validated using the test dataset to ensure diagnostic accuracy. The method is applicable in precision agriculture for analysing the chemical element content in plants. The invention also concerns a computer-implemented method for the remote diagnosis of chemical element content in plants using neural network learning.
