Abstract
This article reports a modified process for the production of synthetic ammonia, in which CO2 in the converted water gas is removed by the synthesized ammonia itself, and the precipitated NH4HCO3 serves as the final product of the factory. NH4HCO3 pills weighing about 1 g are used to overcome the poor physical properties of the NH4HCO3 powder. Extensive field experiments laid down on various soil areas in China showed good crop responses when NH4HCO3 pills were deep dressed.
A laboratory process for the preparation of coated NH4HCO3 pills as a slow-release fertilizer is described. The crop response to slow-release NH4HCO3 pills is discussed.
