Potential of aerial robotics in crop production: high resolution NIR/VIS imagery obtained by automated unmanned aerial vehicle (UAV) in estimation of botanical composition of alfalfa-grass mixture
Objective of this study is to show possibility of use of aerial imagery acquired by UAV equipped with NIR/VIS cameras and estimation of botanical composition and status on case study legume-grass mixture consisted of alfalfa, orchardgrass and Italian ryegrass. Results showed positive correlations between local NDVI values and relative share of alfalfa and Italian ryegrass and negative correlation between orchardgrass and NDVI. Use of aerial imagery acquired by UAV equipped with NIR/VIS sensors showed potential in estimation of botanical composition and sward status but for interpretation of such remote sensed data it is very important to include into the context additional management data.
