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. A soil aeration apparatus, comprising: a frame to move over a ground surface in a direction of travel; a tine holder member; a gear system that imparts compound motions to the tine holder member; at least one curved tine mounted to the tine holder member, the curved tine having a concave edge, a complementary convex edge, and a tip portion, wherein the convex edge cuts through soil and faces generally away from the direction of travel while the curved tine is in the ground surface; and a timing member coupled to the gear system, the timing member being adjustable between a first position to a second position, wherein when the timing member is in the first position, the tine penetrates a ground surface in a first penetration orientation, wherein when the timing member is in the second position, the tine penetrates the ground surface in a second penetration orientation, and wherein the concave edge of the curved tine faces toward the ground surface when the tine exits the ground surface. 2. The apparatus of claim 1, wherein the first penetration orientation causes the tip portion to be oriented substantially perpendicular to the ground surface when the tip portion penetrates the ground surface. 3. The apparatus of claim 2, wherein the second penetration orientation causes the tip portion to be at a forward angular orientation when the tip portion penetrates the ground surface. 4. The apparatus of claim 1, wherein the first penetration orientation causes the tip portion to be oriented at an angle of approximately 75-degrees to approximately 105-degrees relative to the ground surface when the tip portion penetrates the ground surface. 5. The apparatus of claim 2, wherein the epicycle orientation of the tine holder member is an acute angle of about 5-degrees to about 40-degrees from vertical when the first penetration orientation causes the tip portion to be oriented substantially perpendicular to the ground surface. 6. The apparatus of claim 1, wherein the gear system comprises a planetary gear system that imparts the compound motions comprising a revolving motion and rotational motion to the curved tine. 7. The apparatus of claim 6, wherein the revolving motion is imparted by counterclockwise revolution of a planet gear relative to a sun gear and the rotational motion is imparted by clockwise movement of the planet gear. 8. The apparatus of claim 1, wherein the compound motions are imparted to the tine holder member while the curved tine is in the ground surface to form an aeration pocket. 9. The apparatus of claim 1, wherein the tip portion is oriented in a substantially non-perpendicular direction relative to the ground surface when the tip portion exits the ground surface. 10. The apparatus of the claim 1, wherein the compound motions imparted to the tine holder member causes the curved tine to form a non-symmetric aeration pocket. 11. The apparatus of claim 1, further comprising a pull-type frame coupled to at least a pair of wheels, the frame supporting the tine holder member over the ground surface. 12. The apparatus of claim 1, wherein each curved tine includes: a proximal mounting portion to secure the tine to a tine holder member, the proximal portion being substantially straight; and a curved blade portion disposed distally of the proximal portion, the curved blade portion being at least partially defined by the concave edge, the convex edge, and the tip portion so that, as the curved tine is urged in the compound motions through the ground surface, the curved blade portion fractures soil to form an aeration pocket. 13. The apparatus of claim 12, wherein the compound motions are imparted to the tine holder member while the curved tine is in the ground surface so that the curved blade portion fractures soil to form the aeration pocket. 14. The apparatus of claim 1, wherein the gear system imparts compound motions to a plurality of tine holder members, further comprising multiple curved tines mounted to each of the plurality of the tine holder members. 15. The apparatus of claim 1, wherein the timing member includes an adapter portion that couples with one of a handle, a shaft, and a cable for user control of the timing member. 16. The apparatus of claim 1, wherein the curved tine has generally symmetrical lateral side faces. 17. A soil aeration apparatus, comprising: a frame to move over a ground surface in a direction of travel, a tine holder member; a gear system that imparts compound motions to the tine holder member; at least one curved tine mounted to the tine holder member, the curved tine having a concave edge, a complementary convex edge, generally symmetrical lateral side faces, and a tip portion, wherein the compound motions are imparted to the tine holder member while the curved tine is in the ground surface to form an aeration pocket, wherein the convex edge cuts through the soil while the curved tine is in the ground surface, wherein the convex edge faces generally away from the direction of travel while the curved tine is in the ground surface and a timing member coupled to the gear system, the timing member being adjustable between a first position to a second position, wherein when the timing member is in the first position, the tine penetrates the ground surface in a first penetration orientation, and wherein when the timing member is in the second position, the tine penetrates the ground surface in a second penetration orientation.
