You can look up ’average concentration of elements in’. Your county...it will bring up a website with the US...you click on your county and it lists your exact elements...I wrote all of mine down..so that I know..if we have good selenium here...good copper, good iron, etc...that might be helpful
That's a really good start and definitely worth checking out. Just keep in mind that soils do vary, even within a single property. It's also a good idea to know water concentrations of minerals from whatever water source you use for irrigation & your stock, and to keep in mind that some minerals can interfere with the uptake of others.
