Prof Adriaan van Niekerk and Jascha Muller of the Centre for Geographical Analysis (CGA), and Dr Abraham Singels of the South African Sugarcane Research Institute (SASRI), have published their collaborative research assessing the use of multispectral remote sensing to determine fractional absorbed photosynthetically active radiation (fAPAR) in sugarcane. Crop growth models regularly use fAPAR as a calibration variable in sugarcane yield forecasting. The research assesses the relationship between remotely sensed spectral data and in situ fAPAR measurements over two heterogeneous sugarcane growing areas in South Africa.
