Evaluating onions for size, shape, damage, colour and discolouration is the first most important step in classifying them raw material quality, processing horticultural agri-food sectors.

Soil Organic Matter (SOM) is crucial for soil fertility, and effective detection methods are of great significance the development agriculture forestry. This study uses 206 hyperspectral samples from state-owned Yachang Huangmian Forest Farms in Guangxi, using SPXY algorithm to partition dataset a 4:1 ratio, provide an spectral data preprocessing method novel SOM content prediction model area similar regions. Three denoising (no denoising, Savitzky–Golay filter discrete wavelet transform denoising) were combined with nine mathematical transformations (original reflectance (R), first-order differential (1DR), second-order (2DR), MSC, SNV, logR, (logR)′, 1/R, ((1/R)′) form 27 combinations. Through Pearson heatmap analysis modeling accuracy comparison, SG-1DR combination was found effectively highlight features. A CNN-SVM based on Black Kite Algorithm (BKA) proposed. leverages powerful parameter tuning capabilities BKA, CNN feature extraction, SVM classification regression, further improving prediction. The results RMSE = 3.042, R2 0.93, MAE 4.601, MARE 0.1, MBE 0.89, PRIQ 1.436.

Accurate prediction of soil properties is essential for sustainable land management and precision agriculture. This study presents an LSTM-CNN-Attention model that integrates temporal spatial feature extraction with attention mechanisms to improve predictive accuracy. Utilizing the LUCAS dataset, analyzes spectral data estimate key properties, including organic carbon (OC), nitrogen (N), calcium carbonate (CaCO3), pH (in H2O). The Long Short-Term Memory (LSTM) component captures dependencies, Convolutional Neural Network (CNN) extracts features, mechanism highlights critical information within data. Experimental results show proposed achieves excellent performance, coefficient determination (R2) values 0.949 0.916 0.943 0.926 (pH), along corresponding ratio percent deviation (RPD) 3.940, 3.737, 5.377, 3.352. Both R2 RPD exceed those traditional machine learning models, such as partial least squares regression (PLSR), support vector (SVR), random forest (RF), well deep models like CNN-LSTM Gated Recurrent Unit (GRU). Additionally, outperforms S-AlexNet in effectively capturing patterns. These findings emphasize potential significantly enhance accuracy reliability property predictions by both patterns effectively.
