| Abstract: | A discussion is made on the determination of fractions of NH 4 + N, NO 4 N, and soluble organic N in 0.01 mol/L CaCl 2 extraction solution used in tobacco planting soil and sludge. Related methods and steps for fraction determination, which are convenient, fast and suitable for laboratory use in China, are proposed, providing effective monitoring and analytical measures for reasonable recommendation of N fertilizer, agricultural use of sludge, and prevention of N pollution in water bodies and soils. |
