Predicting in situ pasture quality in the Kruger National Park, South Africa, using continuum-removed absorption features

The remote sensing of pasture quality as determined by nitrogen, phosphorous, potassium, calcium and magnesium concentration is critical for a better understanding of wildlife and livestock feeding patterns. Although remote sensing techniques have proved useful for assessing the concentration of fol...
