In the U.K., fertilizer labeling regulations allow for reporting the elemental mass fractions of phosphorus and potassium.The regulations stipulate that this should be done in parentheses after the standard N-P-K values, as in "15-30-15 (15-13-13)".
Micronutrients are consumed in smaller quantities and are present in plant tissue on the order of parts-per-million (ppm), ranging from 0.15 to 400 ppm or less than 0.04% dry matter. [ 32 ] [ 33 ] These elements are often required for enzymes essential to the plant's metabolism.
Now, they’re itching to apply the anhydrous ammonia this winter. Longtime Illini FS Agronomist Howard Brown talked to Stu Ellis for From the Farm, and said farmers should pump their breaks ...

Anhydrous double sulfates of ammonium also occur in the Langbeinites family. The ammonia produced has a pungent smell and is toxic. Airborne particles of evaporated ammonium sulfate comprise approximately 30% of fine particulate pollution worldwide. [18] It reacts with additional sulfuric acid to give triammonium hydrogen disulphate,, (NH 4) 3 ...
Repeated exposure to ammonia lowers the sensitivity to the smell of the gas: normally the odour is detectable at concentrations of less than 50 ppm, but desensitised individuals may not detect it even at concentrations of 100 ppm. Anhydrous ammonia corrodes copper- and zinc-containing alloys, which makes brass fittings not appropriate for ...
