A soil aeration device may include a plurality of arcuate blades mounted to an assembly adapted to rotate and translate the blades proximate a ground surface, thereby forming aeration pockets in the soil. In certain embodiments, the arcuate tines penetrate and fracture the soil while minimizing the amount of soil lifted from the pocket deposited on the top of the soil. In various embodiments, a planetary gear assembly imparts to the tine a translational and rotational movement which creates a fractured pocket in the soil while minimizing the amount of soil lifted from the pocket and deposited on the surface of the soil. In still other embodiments, the arcuate tine may have mounted thereon a coring tube that cuts and removes a plug from the pocket formed in the soil.

What is claimed is: 1. An aeration tine, comprising: a proximal portion including an adapter to secure the tine to a tine holder member, the proximal portion being substantially straight; and a blade portion disposed distally of the proximal portion, the blade portion being substantially curved and including a concave blade edge and an oppositely disposed convex blade edge that converge near a distal tip portion so that, as the blade portion is urged in a compound motion through a ground surface, the curved blade portion fractures soil to form an aeration pocket. 2. The tine of claim 1, wherein when the blade portion is urged in the compound motion through the ground surface, the convex blade edge moves through the soil and fractures the soil. 3. The tine of claim 1, wherein the adapter comprises a means for releasably mounting to the tine holder member. 4. The tine of claim 3, wherein the releasable mounting means includes a threaded cavity. 5. The tine of claim 1, wherein the proximal portion includes a substantially cylindrical portion that extends in a longitudinal direction. 6. The tine of claim 5, wherein the substantially cylindrical portion has a lateral thickness that is substantially greater than the lateral thickness of the blade portion. 7. The tine of claim 1, wherein the blade portion has a thickness equal to or less than about 5/16 inch. 8. The tine of claim 1, wherein the blade portion has a thickness equal to or less than about ⅛ inch. 9. The tine of claim 1, further comprising an aeration tube coupled to the curved blade portion at one of the convex edge or the concave edge, the aeration tube being operable to remove a soil plug as the curved member fractures soil and forms an aeration pocket. 10. The tine of claim 9, wherein the aeration tube is coupled to the curved blade portion at a location spaced apart from the distal tip portion. 11. An aeration tine, comprising: a proximal portion including an adapter to secure the tine to a tine holder member, the proximal portion being substantially straight; and a blade portion disposed distally of the proximal portion, the blade portion being substantially curved and including a concave blade edge and an oppositely disposed convex blade edge that converge near a distal tip portion so that, as the blade portion is urged in a compound motion through a ground surface, the curved blade portion fractures soil to form an aeration pocket, wherein the blade portion is adapted to be urged in a compound motion as it penetrates the ground surface, the compound motion including a rotational motion about a first axis and an orbital motion about a second axis. 12. The tine of claim 11, wherein when the blade portion is urged in the compound motion through the ground surface, the convex blade edge moves through the soil and fractures the soil. 13. The tine of claim 11, wherein the adapter comprises a means for releasably mounting to the tine holder member. 14. The tine of claim 13, wherein the releasable mounting means includes a threaded cavity. 15. The tine of claim 11, wherein the proximal portion includes a substantially cylindrical portion that extends in a longitudinal direction. 16. The tine of claim 15, wherein the substantially cylindrical portion has a lateral thickness that is substantially greater than the lateral thickness of the blade portion. 17. The tine of claim 16, wherein the lateral thickness of the blade portion is equal to or less than about 5/16 inch. 18. The tine of claim 16, wherein the lateral thickness of the blade portion is equal to or less than about ⅛ inch. 19. A tine for aerating a ground surface, comprising: a proximal portion including means for mounting the tine to a tine holder member, the proximal portion being substantially straight and having a central axis extending in a longitudinal plane; and means for fracturing soil to at least partially form an aeration pocket, the fracturing means being disposed distally of the proximal portion and having curved blade edges extending in the longitudinal plane so that, when the fracturing means is urged in a compound motion through a ground surface, the curved blade edges of the fracturing means form an aeration pocket. 20. The tine of claim 19, wherein the curved blade edges of the fracturing means include a concave edge and a complementary convex edge that converge near a distal tip portion. 21. The tine of claim 20, wherein the mounting means includes a threaded cavity. 22. The tine of claim 19, wherein the fracturing means is adapted to be urged in the compound motion as it penetrates the ground surface, the compound motion including a planetary motion defined by a first rotational motion about a first axis and a second rotational motion about a second axis. 23. The tine of claim 19, wherein the proximal portion includes a substantially cylindrical portion that extends along the central axis, the substantially cylindrical portion having a lateral thickness that is substantially greater than the lateral thickness of the curved blade edges of the fracturing means. 24. An aeration tine, comprising: a mounting portion including a mounting cavity that extends substantially straight along a longitudinal axis; an elongated curved member extending distally from the mounting portion and having a concave portion and a substantially complementary and opposed convex portion, the curved member being operable to fracture soil and form an aeration pocket; a tip portion to penetrate into soil; and an aeration tube coupled to the curved member at one of the convex portion or the concave portion and at a location spaced apart from the tip portion, the aeration tube being operable to remove a soil plug as the curved member fractures soil and forms an aeration pocket. 25. The tine of claim 24, wherein at least one of the concave and convex portions include an edge adapted to fracture soil. 26. The tine of claim 25, wherein the aeration tube is coupled to the edge of the convex portion. 27. The tine of claim 24, wherein the concave portion and the and the convex portion converge near the tip portion. 28. The tine of claim 27, wherein the aeration tube is coupled to the curved portion at the location spaced apart from the tip portion so that the tip portion is operable to penetrate into soil before the aeration tube removes the soil plug. 29. The tine of claim 24, wherein elongated curved member is operative to fracture soil that is compacted by the aeration tube.
