文摘

A greenhouse pot experiment was conducted to study the effects of conventional nitrogen fertilization on soil acidity and salinity. Three N rates (urea; N0, 0?kg?N?ha?; N1, 600?kg?N?ha?; and N2, 1,200?kg?N?ha?) were applied in five soils with different greenhouse cultivation years to evaluate soil acidification and salinization rate induced by nitrogen fertilizer in lettuce production. Both soil acidity and salinity increased significantly as N input increased after one season, with pH decrease ranging from 0.45 to 1.06 units and electrolytic conductivity increase from 0.24 to 0.68?mS?cm?. An estimated 0.92?mol H+ was produced for 1?mol (NO2 ?/sup> + NO3 ?/sup>)-N accumulation in soil. The proton loading from nitrification was 14.3-7.3 and 12.1-8.2?kmol H+?ha? in the center of Shandong Province under N1 and N2 rate, respectively. However, the proton loading from the uptake of excess bases by lettuces was only 0.3-.5?% of that from nitrification. Moreover, the release of protons induced the direct release of base cations and accelerated soil salinization. The increase of soil acidity and salinity was attributed to the nitrification of excess N fertilizer. Compared to the proton loading by lettuce, nitrification contributed more to soil acidification in greenhouse soils.
