Priming effect of biuret addition on native soil N mineralisation under laboratory conditions
This study was carried out to quantify the priming effect of biuret on native soil nitrogen (N) mineralisation during a 112-day incubation. Addition of biuret (100 mg 15N-labelled biuret kg −1 soil) increased the turnover rate constant of soil organic matter and had a positive priming effect on nati...

Summary: | This study was carried out to quantify the priming effect of biuret on native soil nitrogen (N) mineralisation during a 112-day incubation. Addition of biuret (100
mg
15N-labelled biuret kg
−1 soil) increased the turnover rate constant of soil organic matter and had a positive priming effect on native soil N mineralisation in two soils. The additional mineralisation was 0.65% of the total soil N (equivalent to 47.1
kg
N
ha
−1) in a sandy loam soil and 0.62% of the soil N (equivalent to 46.5
kg
N
ha
−1) in a silt loam soil. |
