For On Gardening I'm Stan DeFreitas, Mr. Greenthumb. We're talking about the earth box. We talked about adding the soil which we've added to the earth box and we've got a fertilizer which we've applied to the base. It happened to be a nitrogen, phosphorus and potassium type fertilizer and we kind of raked it in and kind of had good even distribution of the fertilizer. Now one of the things that you'll learn in the earth box, and you'll also learn when you do traditional gardening, is you normally want to cover over that fertilizer. Why? Because 78% of the atmosphere is nitrogen. If you leave a fertilizer right on the surface what happens? A lot of it nitrofies and goes right into the air. It goes back into the air. So here you are, you've spent your money on fertilizer, and when you look at the fertilizer you say why aren't I getting the value from it that I should? If you cover over the earth box with more soil you will get the kind of results that you're looking for. Now this little trick is also good when you're doing backyard gardening. If you can cover over your fertilizer you will get it to be more effective and more efficient and your dollar will go further. For On Gardening I'm Stan DeFreitas, Mr. Greenthumb.
