What are the typical analysis of burnt coal / hydrocarbon of the 16 elements required in soil,?

Question

for vegative growth., By percentage or weight of one (2000 lb.)ton.

There are ten's of thousands of tons of coal ashes near my retirement home, in Mexico, and I would like to put some of it to work in my pecan orchard, and on the pasture grass.

YES, I would naturally have another soil analysis completed (preferably by Texas Tech. / Lubbock) BEFORE any application of the ashes.

Thank You for any information.

Answer 1

Coal ash will normally have all sixteen (or More) of the required elements plus many more.  Since the coal came from living organisms it contains the elements necessary to those living organisms.  The combustion process would normally volatilize the majority of the carbon, hydrogen, oxygen, sulfur, nitrogen, and chlorine.  It might also volatilize the fluorine, bromine and iodine.  The residue will contain essentially all of the metals and many of the nonmetals.  Your soil analysis may be less critical than an analysis of the coal ash.  the soil analysis should tell you what you lack in the soil.  The analysis of the coal ash will tell you what you are adding back.  both are important.

My experience with the college at Lubbock is that they are weak in evaluating the trace elements.

The list supplied by the previous answer does not include Potassium, some Nitrogen, and other elements that are probably there
