The Second Derivative of the NDVI Time Series as an Estimator of Fresh Biomass: A Case Study of Eight Forage Associations Monitored via UAS
The estimation of crop yield is a compelling and highly relevant task in the scenario of the challenging climate change we are facing.With this aim, a reinterpretation and a simplification of the Food and Agriculture Organization (FAO) fundamentals are presented to calculate the fresh biomass of forage crops.A normalized difference vegetation index
