　　Nitrate(NO3)leaching from agricultural soils represents a substantial loss of fertilizer nitrogen(N)and may lead to considerable contamination of ecosystems.The objective of this study was to quantify NO3-N leaching losses with ion exchange resins for two tillage-straw management practices in the Yaqui Valley,NW-Mexico.
