Amino Acids ( for seed growth)

[DavidCampen]

I combine equimolar quantities of aspartic acid and ammonium carbonate to produce the ammonium aspartate that I use in my formulations. I dissolve the ammonium carbonate in water and then slowly add the equimolar amount of aspartic acid; carbon dioxide is evolved resulting in a solution of ammonium aspartate.

The last formulation that I used is given here:

Those amounts are to make 2 liters of concentrate that I then add to my RO water, using a chemical injection pump, at the rate of about 1:100 every time I water (thus the 2 liters of concentrate produces about 200 liters of watering solution).

I mispoke, I use 1/2 mole of ammonium carbonate per mole of aspartic acid. This gives me 1 mole of ammonia per mole of aspartic acid. But actually, ammonium carbonate has an imprecise composition; I assume the Baker's Ammonia to be 31% ammonia, so for 100 grams of aspartic acid I use 41 grams of Baker's Ammonia to give 113 grams of ammonium aspartate.
