Unfortunately, the color itself won't give you much more information than the amount of organic matter and oxides/hydroxides. The amount of carbonate and some silicates might also be detected, but those values would be very vague without further examination of the soil. If you want to get more information you would need some more data. The grain sizes for ...

If you have no prior information that event B depends on event A, it's a logical error to claim event A causes event B just because you find they are correlated. Let's say you collect a large data set of how people use their computer-mouse, and show that there is some change in a statistic of this data preceding an earthquake. That cannot not prove that the ...

The AQI calculation does not require that all pollutants be measured. Instead, it uses the pollutants that are available and then uses a function (chosen by the overarching regulatory agency) that equates health risk categories to the pollutant concentrations. The pollutant with the highest health risk (at present concentrations) will effectively determine ...

As our planet gets warmer less area will be avaliable for farming so vertical farming will be needed to supply food for a growing population. Vertical farming will not replace traditional farming but it will be an addition to this. Vertical farming can be effective in growing food by using less energy,We can use only the part of the light spectrum that ...

Ambient or roadside concentrations for each pollutant, over different averaging times, will be converted into an index value. In general, there are three common methods to achieve this. The most popular approach is often called the US-based system. Pollutant concentrations for each pollutant are transformed onto a normalised numerical scale of 0 to ...

This is to a certain degree possible. See this article: https://dl.sciencesocieties.org/publications/sssaj/abstracts/77/6/2173
