Figure 4

N2O flux from grassland, cropland, and Tamarix. Each point represents the arithmetic mean and standard error of four replicates. Arrows pointing upward indicate fertilization events on the cropland, while those pointing downward indicate the presence of dead pill-bugs in the Tamarix or irrigation and covered by the plastic film in the cropland (left to right). Red color arrows represent specific events in cropland and blue for Tamarix.
