Abstract:
Uptake and recovery of fertilizer N (Nitrogen) applied to spring wheat was monitored over a 3-yr period in a semiarid region. Tagged fertilizer with enrichment from 8. 9 to 28. 5 atom % **1**5N was applied as KNO//3 at rates equivalent to 180 kg N ha** minus **1 as a single application or split equally over 3 yr. The wheat was grown in 1. 25- multiplied by 1. 25-m open plots and in 0. 3-m diam microplots enclosed by hard plastic tubes that were inserted 0. 6 m into the ground. The **1**5N enrichments in plant and soil were determined by emission spectrometry. In open plots fertilizer N recovery in plant and soil was 976 g kg** minus **1 in the first year and 697 to 721 g kg** minus **1 in subsequent years. In the tubes, equivalent recoveries were 755 to 841 g kg** minus **1 in subsequent years. In the tubes, equivalent recoveries were 755 to 841 g kg** minus **1 and 377 to 560 g kg** minus **1. The greater loss in the tubes is attributed to denitrification that could have occurred under excess waterlogging caused by the rim of the tubes that protruded about 0. 05 m above the soil surface.
