Description
In the Waikato district of New Zealand, large areas of peat soils are used for pastoral agriculture. This study examined the urinary nitrogen (N) transformations after application of ISN•labelled urine to peat soils at 2 stages of development, with and without a water table present. The peat soil with the longest development history had greater plant recovery of urine N but also had greater denitrificalion losses. The presence of a water table reduced both immobilisation and plant uptake of urinary N and increased loss by denitrification.
