What happens on a field when working in the ground using iron implements is the following: the cosmic powers that are very much needed in the ground are interrupted. This results in an imbalance in the ground. The supply of information from the cosmos is cut. This information is necessary to give direction to processes in plants and soil. This lack of information will not be directly visible, the soil will still contain some old information, however, as years go by this will fade away. Then an empty dead soil will remain. By binding this instrument to an implement or by walking with it on a field the cosmic radiation will be repaired again. You can also take this implement in your hands and walk, in thought, with it on the field. This is far easier yet.
Furthermore you can use good quality compost, which helps to make the connection between earth and cosmos.
