Soil consultants have traditionally used electrical conductivity to measure salinity. Conductivity can tell us much more about the physical structure and health of the soil, though, and can help 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 and illuminating our home.
In the human body, electricity controls the flow of blood from the heart to all the organs. In the same way that flipping a switch turns on a light, 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. For example, the intake of high-salt foods can lead to a higher pulse rate. A higher pulse rate forces the heart and other organs to have to work harder in order to function properly. This extra work certainly 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, they affect the human body in different ways physiologically. Inputs into any biological system, whether human, animal, plant, or soil, affect the system in unique ways. Continue Reading →
