I have some Calcium Nitrate fertilizer which i would like to know the composition of. Supposedly it contains by
weight:15.5% Nitrogen of which: 14.4% is nitrates 1.1% is ammonium18.8% Calcium of which: 18.8% is soluble (implying no Calcium Hydroxide or
Calcium Carbonate)The salts should amount to 34% , assuming the rest is water how is it not a liquid when the solubility of Calcium Nitrate is
121g/100g at room temperature.What irks me too is that it supposedly reacts as a caustic which is counter intuitive for a mixture containing ammonium
which in soil should be oxidized to nitrite and then too nitrate. Calcium Nitrate is slightly acidic too.Is there something else in it which is not
mentioned or does Calcium Ammonium Nitrate have lower solubility and some weird interaction in soil?
EDIT: Never mind, please delete

Don't feel bad, I've had 4 batches of what is supposed to be the same calcium nitrate fertilizer and they have all been different. 3 were in the
branded bag by "Yara" and the 4th was a plain white bag, supposedly re-packaged from a bulk purchase. All 4 have acted differently, 2 bags reacted
strongly with NaOH/KOH producing copious amounts of ammonia and I think a lot of heat, and this was with a dry mixture the other 2 bags didn't react
at all when mixed dry and only slight smell of ammonia when a base was added.
2 bags would not completely dissolve in water, it seemed like it was either Ca(OH)2 or CaCO3 though it was off-white. I have been lead to believe
that the fertilizer is made from ammonium nitrate and CaO, though I'm not sure if that makes Cal Nit or CAN.
It seems that Cal Nitrate and CAN both widely vary in their composition and quality, even when it is supposedly "brand" name stuff. AJKOER - 30-9-2018 at 11:11

Could it be that manufacturers of calcium nitrate and CAN products have been given the green light to sell poor quality products, as it likely
efficiently and cheaply compromises most applications of the product other than its use as fertilizer?
This would in essence give money to the manufacturers, but could also result in a consumer preference competition among adulterated products (which is
what this thread may be an example of).
In all, I guess this product modification would be better than a ban (due to rare misapplications of the product) given that fertilizers are essential
for the cultivation of crops.
