Townsend L R 1967 Effect of ammonium nitrogen and nitrate ni- trogen, separately and in combination, on the growth of the highbush blueberry. Can. J. Plant Sci. 47, 555-562.Townsend L R 1967 Effect of ammonium nitrogen and nitrate nitrogen, separately and in combination, on the growth ...
Both ammonium nitrogen and nitrate nitrogen are available nitrogen sources for crops absorbingdirectly.The classical experiments during 1930s show that: the fertilizer efficiencies of two nitrogen sources are equivalence,but they have the differences in different conditions.Based on discussion of the absorp...
Impacts of diazinon (O,O-diethyl O-2-isopropyl-6-methylpyrimidin-4-yl phosphorothioate), imidacloprid [1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine] and lindane (1,2,3,4,5.6-hexachlorocyclohexane) treatments on ammonium, nitrate, and nitrite nitrogen and nitrate reductase ...
利用砂培试验,研究了铵态氮和硝态氮,以及不同铁供应水平对旱稻和水稻生长与铁营养状况的影响。结果表明:供铁显著促进了水稻和旱稻的生长,提高了铁吸收量;与铵态氮相比,不供铁时硝态氮加重了缺铁旱稻和水稻的铁缺乏状况。就氮素形态的影响而言,铵态氮明显促进了旱稻和水稻的生长,表现在株高、地上部干重的显著增...
Ammonium, nitrite, and nitrate nitrogen levels in the root zone of blightaffected and healthy trees in a 35yearold commercial orange grove were monitored at 30day intervals for 2 years. There was essentially no difference in NH4N and NO2N; however, at four sampling dates and overall, the ...

We conducted continuous-flow experiments on intact sediment cores from Laguna Madre, Sabine Lake, East Matagorda Bay, and Nueces Estuary to evaluate internal nitrogen (N) sources, sinks, and retention mechanisms in Texas estuaries having different salinities. Mean ammonium (NH4+) flux ranged from...
In this study, basic sediment properties, nutrient flux, and nitrogen cycle (including denitrification, anaerobic ammonium oxidation [anammox], nitrification, and dissimilatory nitrate reduction to ammonium [DNRA]) were investigated at two sampling sites with different tree ages in the mangrove region of...
