Critical Factors Affecting Water and Nitrogen Losses from Sloping Farmland during the Snowmelt Process

Water and nitrogen losses from farmland during the snowmelt process play a vital role in water management cold regions. To explore mechanisms factors contributing to loss different sloping farmlands period, field experiments were conducted under two slope treatments (8° 15°), soil content (SWC) treatments, snow equivalent (SWE) (5 mm 10 mm) seasonal freezing agricultural watershed of Northeast China. The results showed that process, SWE was most important factor affecting production through surface total runoff farmland, followed by slope. yield high (HS) ranged 1.76 8.15 1.65 12.62 times higher than those low (LS) treatments. generation advanced compared with induced preferential nitrogen. A promoted this function Enhanced infiltration combined resulted greatly decreased gentle LS (GS_LS) These findings are valuable for accurately describing cycling seasonally farmland.
