At first blush this sounded like a neat idea. Farmers could get a text message when their crop was needing water. http://www.foxnews.com/printer_friendly_story/0,3566,509547,00.html
It was developed to save water, but it suddenly came to me that this is another reason for the corporate farmer not to set foot in the fields.
I am sure there are many versions of this saying, but it is commonly agreed in concept that the best thing for a crop is the footsteps of the farmer in the field.
I can see a cartoon of the future where a farmer in suit and tie goes to see how the water is flowing, only to find out that the text came because the plants were no longer there from an insect attack or some other calamity that could have been stopped if the farmer had been in the field.
