Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. For hydroponic use, check the reservoir.

Both colour and texture are indicators of properties of the soil and are taken into account when interpreting other soil chemical results. Organic carbon. Organic carbon is a measure of the organic matter present in soil. Does it soil organic matter really matter?

This can be done because the mass of water is the same as its volume (in Metric units).

Your runoff ppms sound high to me. But, I don't know if that's a universal metric. It sounds like some soils can have high ppm runoff without any problems like lockout. My soil is light/airy with very little nutrients built into it.

If you want to estimate the value in pounds per acre, you can simply multiply the ppm value by two. When a soil contains 3 wt% of an element, the concentration in ppm is 3x10'000 = 30'000 ppm. To convert wt% in ppm, one should MULTIPLY the wt% value by a factor 10'000.
