Inorganic Nutrients Increase Humification Efficiency and C-Sequestration in an Annually Cropped Soil
Fig 3
Mean FF-N, -P, -S concentrations (%) to 1.6 m depth in the <2 mm soil fraction in 2006 and the (+) nutrient treatment in 2012.
Data are means and SEM, n = 4. (* indicate a significant difference between 2006 value and 2012 value from (+) nutrient treatment P<0.05; ns = not significant)
