Nitrogen (N) losses negatively impact groundwater quality. Spring wheat genotypes varying in N-fertilizer recovery were studied (by using lysimeters) for their potential to minimize NO3-N leaching during spring and summer, over a three-year period. Additionally, we examined to what extent root growth and NO³N leaching explain the well-known difference found between apparent and isotopic N recovery. The genotypes were grown under low (2 g m-²) and high (27 g m-² 9) N fertilizer supply. On average, the apparent and isotopic recoveries of N fertilizer by wheat were 43 per cent and 51 per cent, respectively. The three genotypes varied in fertilizer N recovery but not in NO3-N leaching, which only accounted for 15 per cent of the applied N fertilizer. The differences in N uptake, fertilizer N recovery and root growth among the genotypes were not associated with the leached NO3-N because root growth and N uptake were not well synchronized with NO3-N leaching. Already at stem elongation 70 per cent to 98 per cent of the season-long NO3-N leaching had already taken place. Thus, the ability to minimize in-season NO3-N leaching by using spring wheat genotypes with higher fertilizer N recovery was limited because maximum N leaching occurred in the early crop season. application/pdf doi:10.3390/agronomy6020029 issn:2073-4395 http://ri.agro.uba.ar/greenstone3/library/collection/arti/document/2016herrera eng info:eu-repo/semantics/openAccess openAccess http://ri.agro.uba.ar/greenstone3/library/page/biblioteca#section4 Agronomy Vol.6, no.2, 29 1-15 http://www.mdpi.com/ LYSIMETERS FERTILIZER N RECOVERY N UPTAKE ROOT MINIRHIZOTRON Little potential of spring wheat genotypes as a strategy to reduce nitrogen leaching in Central Europe info:eu-repo/semantics/article info:ar-repo/semantics/artículo publishedVersion info:eu-repo/semantics/publishedVersion
