This soil requires digging… but that’s just an opportunity for some good exercise!  I dug a hole in the ground to make another compost pile, which will some day be a garden bed when the compost is finished.  I was surprised how rich the soil is under the canopy of trees and fallen leaves.  Why buy topsoil when you could dig it up from your property… this garden soil is free with the added bonus of a “free” workout.  No gym membership required.  :-)   Gardening can be good exercise if you use hand tools instead of automated equipment.

While planning the placement of the future garden row, I used a compass.  I wanted my rows to be perfectly aligned with west and east for maximum sunlight exposure from the south.  In the video below, you can see how the shadows all fall from south to north.  I plan to cut some of the smaller trees to remove some of the shade so that I can plant a row of garden plants.

I thought I discovered a magnetic anomaly, so I recorded the process of figuring out the source of the magnetic disturbance.

Conclusion

A compass is easily disoriented when it is near a magnetic material, like iron or another magnet.  Rebar is made from Iron, which is magnetic, and that was the cause of the disturbance on my compass readings.  I wonder how effective a compass would be in locating an iron deposit in the ground.  Instead of using an electronic metal detector, maybe a strong compass could help indicate the presences of magnetic elements in the ground.
