False:

Most nitrogenous fertilizers are water-soluble, but not all. Here are some common nitrogenous fertilizers and their water solubility:

Urea (CO(NH2)2): Highly soluble in water.
Ammonium Nitrate (NH4NO3): Highly soluble in water.
Ammonium Sulphate ((NH4)2SO4): Soluble in water.
Calcium Ammonium Nitrate (Ca(NO3)2 + NH4NO3): Soluble in water.
Potassium Nitrate (KNO3): Soluble in water.

However, some nitrogenous fertilizers are not soluble in water, such as:
Calcium Cyanamide (CaCN2): Partially soluble in water.
Urea-Formaldehyde (CO(NH2)2 + CH2O): Insoluble in water.

So, while most nitrogenous fertilizers are water-soluble, there are some exceptions.
