The effects of precipitation of calcium carbonate on soil pH following urea application

Abstract:

This thesis describes a series of experiments both in solution systems and soil systems to study the precipitation of calcium carbonate in soils and the effects of the precipitation on soil pH after urea had been applied.

(1) A gas bubbling system has been established which introduces ammonia at a steady rate to the reaction solution and keeps it equilibrated at 0.00484 atm partial pressure of carbon dioxide.

(2) In a non-seeded system, the effects of calcium, urea, Mg (magne...
