An agricultural yield apparatus with a container made of a material that is impermeable to water and inert without leaching impurities to the surrounding natural environment and thereby is effective in segregating contents of the container from the surrounding natural environment and blocking seepage of the contents to the surrounding natural environment. The container encloses nutrients, water and a growth medium such as soil. The top of the container is closed except for at least one water and nutrition port and at least one vegetation growth port (or neck). The trunk of the vegetation passes through the at least one vegetation growth port (or neck). The container may be closed by a root membrane overlay having holes. The trunk of the vegetation passes through the holes in the holed root membrane overlay. Root direction channels may be beneath the overlay.
