The first satellite was launched into space back in 1957. In the 1970s, satellites started being used for agricultural needs. That's when scientists calculated the NDVI index that helps farmers understand what's happening with plants in their fields. But 50 years ago, the NDVI index couldn't be used to its full potential. Image accuracy was about 50 meters, and NDVI couldn't be calculated in cloudy weather.
The next breakthrough in satellite use for farmers came in 2015, when a satellite with a spatial resolution of 10 meters became available.
Firstly, this new resolution provides a clear picture of what's really happening in different areas of a field. Secondly, with the invention of smartphones and apps for farmers, technology became more affordable, allowing any farmer in the world to monitor the NDVI index in their fields. However, image quality still suffers during cloudy weather, and there's no solution for this yet that works everywhere on earth. Benefits:
Satellite monitoring makes it possible to remotely monitor plant development using NDVI, CCCI, NDRE, MSAVI, and other vegetation indices, find problem areas in the field, identify crops, and predict yield. What we do:
We collect open data from the Sentinel-2 satellite, process it, calculate various indicators, and display them in the OneSoil app. This helps farmers outline field boundaries, view the NDVI index, identify productivity zones, and create maps for variable-rate seeding and fertilizer application. In addition,
we're developing Cloud-Free NDVI technology to display NDVI even in cloudy weather
. This feature is already available in Argentina.
