A preliminary research on the effect of nitrogen and phosphorus supply on N2O emission by crops

Abstract

Abstract: The preliminary results with detached leaves and seedlings of corn, soybean and sorghumfrom pot and field experiments indicate that inorganic nitrogen supply can significantly enhance the N₂O emission and NO₃^- concentration in plants in the case of phosphorus deficiency and of less light, but phosphorus Supply and sunlight condition can markedly reduce the N₂O emission and NO₃^- concentration in the plants.It's concluded seemed thatthe N₂O emission is a kind of physiological protection to avoid NO₃^- accumulation in plantswhen nitrogen metabolism in plants is in disorder and mineral nitrogen is in over supply.

Key words: Nitrogen and phosphorus supply, Crops, N₂O emission, potential distribution, MaxEnt model, dominant species
