The Fate of Nitrogen Fertilizer in Paddy Soils
The balance sheet of fertilizer nitrogen in the soil-plant system provides basic information for evaluating agricultural practices in general and for the rationalization of fertilization system in particular. Besides, it also has a referential value for the characterization of the fertilizer concerned and for the development of new fertilizers.
