The ID number that comes with your data point is a way for us to handle and organize all the incoming data from around the world. Maybe, if you wanted an easier way to look through your data in the project viewer, you could add some more answers to your Multiple Choice questions. Right now, you only have one answer for each, which means all your data will all be lumped together. Maybe adding additional answers, or new questions for variety of sugar cane, or different treatments. This way when you go to look at your data next time, you can see how all the different varieties compare.
