Predicting nickel concentration in soil using fractional-order derivative and visible-near-infrared spectroscopy indices
Jianfei Cao, Wei Liu, Yongyu Feng, Jianhua Liu et autres
Accurate monitoring and estimation of heavy metal concentrations is an important process in the prevention and treatment of soil pollution. However, the weak correlation between spectra and heavy metals in soil makes it difficult to use spectroscopy in predicting areas with a …
