Leaf Spectroscopy can measure seven common stresses that crops encounter. The crop leaf stressors are drought, nutrient deficiency, temperature, pests, diseases, salinity, and herbicides. Spectral changes due to physiological, anatomical, and chemical alterations triggered by stress are used in its measurement. Various methods are visual, multispectral, hyperspectral, thermal imaging, and light interaction. Yield depends on… Continue reading…
