Estimating grass nutrients and biomass as an indicator of rangeland (forage) quality and quantity using remote sensing in Savanna ecosystems

Author: Ramoelo, Abel ; Cho, Moses A ; Mathieu, Renaud SA ; Skidmore, AK ; Schlerf, M ; Heitkönig, IMA Date: Oct 2012 Grass quality and quantity information plays a crucial role in understanding the distribution, densities and population dynamics of herbivores (i.e. livestock and wildlife). Leaf nitrogen (N) and biomass (g/ m2) are indicators of grass quality ... Read more
Explaining Leaf Nitrogen Distribution in a Semi-Arid Environment Predicted on Sentinel-2 Imagery Using a Field Spectroscopy Derived Model

Author: Ramoelo, Abel ; Cho, Moses A Date: Feb 2018 Leaf nitrogen concentration (leaf N, %) is an essential component for understanding biogeochemical cycling. Leaf N is a good indicator of grass or forage quality, which is important for understanding the movements and feeding patterns of ... Read more
Hyperspectral remote sensing techniques for grass nutrient estimations in savannah ecosystems

Author: Ramoelo, Abel ; Cho, Moses A ; Mathieu, Renaud SA ; Skidmore, AK ; Scherf, M ; Heitkonig, I ; Prins, HHT ; Asner, G Date: Mar 2010 Information on the distribution of grass quality (nutrient concentration) is crucial in understanding rangeland vitality and facilitates effective management of wildlife and livestock. The spatial distribution of grass nutrient concentration ... Read more
Modelling nutrient concentration to determine the environmental factors influencing grass quality

Author: Dudeni-Tlhone, N ; Ramoelo, Abel ; Cho, Moses A ; Debba, Pravesh ; Mathieu, Renaud SA Date: Oct 2010 This paper uses the spatial and the least squares (Analysis of Covariance-ANCOVA) regression methods to evaluate the important environmental factors in estimating quality grass for grazing (based on the nitrogen (N) content in grass). The ... Read more
