Do you know such statements as "In the old days it worked without it “? Yes, that may be right. I can’t remember that farmers in my childhood were equipped with crazy technology. But the argument “earlier” does not count anymore.
The world population is increasing day by day. Starting around the year 1700 to date, the world population has increased from about 0.5 billion people to over 7 billion people. Especially industrialization has been a major accelerator for this development. At the same time space for fields continued to decline.
ThApart from climate change, we have found important arguments for why agriculture must be further optimized just in the previous paragraph. And if sensors, digitization etc. are available, they should also be used for agriculture.
If we then deal with climate change, we will be back where we started: the soils have to be controlled and, if necessary, irrigated automatically. Sensors have to take over control and must trigger the irrigation systems. But only if the weather stays dry.
