Do plants absorb different minerals depending on what kind of soil they are in? If so, do they have a way of regulating how much of a particular mineral they absorb? I'd imagine desert soil is higher in certain minerals than, say, volcanic soil or mountain soil.
I know commercial fertilizers use the the NPK ratio, but how do desert plants regulate that ratio internally?

Plants absorb different nutrients depending on the chemical and physical composition of the soil. Desert soils are usually lower in all nutrients, and therefore desert plants are usually efficient in their nutrient use. Measuring the nutrient use is a very important tool for sustainable agriculture, and is at the forefront of today’s research. We can measure online in order to provide the farmer with accurate data, so he can use exact amounts of nutrients. This creates a sustainable practice - maximizing yield with minimal waste. Nutrients can be absorbed, assimilated, or stored depending on the specifics of the species and the conditions.
