An automated colorimetric method for the determination of urease activity in soil and plant material |
|
| Abstract: | Abstract An automated colorimetric method Cor determining urease activity in soils and plant material is described. The method, using ammonium determination by the nitroprusside‐catalysed indophenol reaction, is Caster and more precise than a colorimetric measurement of urea. |
