The PLSR-ML fusion strategy for high-accuracy leaf potassium inversion in karst region of Southwest China
Potassium is a critical macronutrient for plant growth, yet accurately and rapidly estimating its content in karst regions remains challenging due to complex terrestrial conditions. To address this, we collected leaf potassium content and reflectance data from 301 plant samples across nine karst reg...
