What is better ammonium nitrate or urea? Fertilizer ...

Urea is a softer fertilizer. The main difference is that nitrate is a mineral, and urea is an organic compound. Plants assimilate nitrogen from urea more slowly than from saltpeter, but the nutritional effect is longer. When saltpeter is added, it increases the overall acidity of the soil, and urea does not change it.
