What sensors tell about the crop environment
MetadataShow full item record
Our great-grandparents and their ancestors did not use any sensor but knew their fields perfectly. The reason is that they had their feet on the ground, literally. They had to walk throughout their fields either sowing, weeding or ploughing with mules. And they had time to know which areas in their fields were better than others. With the appearance of the tractor and agricultural mechanization in general, things started to go faster and fields started getting bigger, so much so, that sensors are now required to provide farmers with the information they once had. In this 4th Precision Ag Corner issue we will discover how different sensing systems can help farmers gather information on the surroundings of their crops. In the next issue of the magazine, we will cover the techniques allowing to sense the crops properties themselves.
