Priming effect, fertilization

Since the fertilizing effect of N and P forms is of prime interest in natural waters, several prominent biologists working in the limnological field were approached to determine their opinion of the desired analytical classification and the sensitivity and detectability of analytical techniques that would be necessary to make N and P analysis meaningful in the determination of the fertilizing potential of a water. 

Inorganic nitrates—sodium nitrate, potassium nitrate, and ammonium nitrate—play major roles in the fertilizer, explosives, and propellant industries. Ammonium nitrate has been the material of prime interest for commercial exploitation because of its favored chemical nature and cost-effectiveness. The commercially available forms of these polycrystalline nitrates are gen-...
