Does anyone know how to build a Paramagnetic Soil Meter?

Does anyone know how to build one of these, a Paramagnetic Count Soil Meter, follow the link. I know it consists of two air coils with an impedance circuit measuring the difference between two coils when a low level magnetic substance is placed in one of the coils. Can anyone help?
