Visible near-infrared spectroscopy and pedotransfer function well predict soil sorption coefficient of glyphosate Ghent University
The soil sorption coefficient (K-d) of glyphosate mainly controls its transport and fate in the environment. Laboratory-based analysis of K-d is laborious and expensive. This study aimed to test the feasibility of visible near-infrared spectroscopy (vis-NIRS) as an alternative method for glyphosate K-d estimation at a country scale and compare its accuracy against pedotransfer function (PTF). A total of 439 soils with a wide range of K-d values ...
