Imagery changing agriculture: experiences in Argentina, Brazil & South Africa
Satellite imagery is a reliable and permanent source of data, easily accessible to producers, consultants and technicians. The new satellite constellations made available from the 2016/2017 season allow access to high resolution and revisit frequency images.
In a first level of image processing, we obtain green index maps (NDVI) that represent the photosynthetic activity of the crops and allows remote tracking of the development of the crops.
Argentina, Brazil and South Africa are using these tecnologies to support for field visiting and scouting to monitoring weeds, pests and diseases, support for plant counting and re-seeding decisions, waterlogging delineation, variable nitrogen fertilization on corn and wheat, protein estimation and correction on deficiencies on wheat and yield estimations.
