Effects of different types of salt and alkali stresses on soil properties and nitrification in a calcareous desert soil. a Soil water content (%), b salinity (dS m−1), c pH, d NH4-N (mg kg−1), e NO3-N (mg kg−1), and f potential nitrification rate (μg NO2-N g−1 h−1). Columns and error bars represent the mean ± standard error (n = 3), respectively. CK, control treatment without salt or alkali stress; CS, NaCl stress treatment; SS, Na2SO4 stress treatment; AS, Na2CO3 + NaHCO3 stress treatment
