US Patent 7707771 Plant cultivation apparatus

A plant cultivation apparatus includes a water resistant sheet of material, with at least one opening formed in the sheet to enable growth of a plant through the opening. A fertilizer band, which can be contained within a membrane, is affixed to an underside of the sheet and includes a predetermined amount of a plant nutrient. The inventive apparatus is placed on top of a growing medium. With the fertilizer band in contact with the growing medium, a nutrient gradient is established so that plants growing through the openings formed in the sheet receive nutrition.
