Electrical Conductivity: The Pulse of the Soil

Traditionally soil consultants have used electrical conductivity to measure salinity, however conductivity can tell us much more about the physical structure and health of the soil. Based on these direct measurements, electrical conductivity can also indirectly measure crop productivity.

When we walk into our home on a dark night, the first thing we usually do is turn on the lights. With the flip of a switch, we complete the electrical circuit initiating the flow of electricity to the light bulb, illuminating our home.

In the human body, electricity controls the flow of blood from the heart to all organs. In the same way we flip a switch turning on the lights, electrical signaling in the body tells the heart when and how often to contract and relax. These electrical signals can be altered by the intake of nutrients. Case in point, the intake of high-salt foods can lead to a higher pulse rate. With a higher pulse rate, your heart and other organs must work harder in order to function properly. Certainly this extra work puts added stress on the body. In contrast, consuming a balanced form of energy can reduce the stress put upon the body.

Waking up in the morning and only consuming caffeine does not give you the same energy as waking up and eating a balanced breakfast. While both inputs may increase your readiness in the morning, physiologically they affect the human body in different ways. Inputs into any biological system whether human, animal, plant or soil consequently will affect the system in different ways. Continue Reading →
