Movement of Fertilizer Nitrogen in Soil and Use of Chloride as a Nitrogen Tracer
Listed in NASA Earthdata CMR
The distribution of nitrogen and chloride in the soil profile for 1 year was studied.
Description
NH4-N in N fertilizer was absorbed in the surface soil and remained within a depth 10 cm. NO3, nitrified nitrogen, moved downward.
The profiles of distribution were different between NO3 and Cl in 1.5 months after fertilization. After then, the difference became smaller. The movement of NO3 and Cl was related to soil physical property.

The movement was very slow at a depth of below 40 cm. The distribution curve of N and Cl in soil profile was fitted with Poisson distribution. The movement of N applied in NO3-N can be estimated by that of chloride.
