Read the tutorials and give it a try. This is a very user friendly site. Start with the simple stuff like a basic article until you figure out what you want to do. Don't be afraid of errors to begin with because Hub Pages will alert you to anything you may be doing wrong. The important thing is that you publish your first hub. Be sure to edit for spelling and grammar. Add pictures and extra text capsules to divide the page up for a pleasing display. And its very important that you list the proper category for the subject you are writing about. Farming is a good subject.
I'm looking forward to reading your hubs. Welcome to Hub Pages.
