Prediction of soil selenium content and model optimization for a watershed in the Taihang Mountains based on machine learning models

2026-07-08

Abstract excerpt

<title>Abstract</title> <p> Selenium(Se) is an essential trace element for humans, and the spatial distribution of soil selenium governs regional ecological security and agricultural product quality. Rugged terrain and limited sampling accessibility restrict soil selenium modeling in small mountainous watersheds of the Taihang Mountains. A total of 107 topsoil geochemical samples were collected from a typical wa...
