97 Symposium--Linking Soil Enzyme Activities to Ecosystem Functions: I

Oral Session
S03 Soil Biology & Biochemistry
Soil enzyme assays are easy to perform and can be widely adapted for environmental monitoring. However data interpretation is challenging. This symposium will cover recent advances in soil enzymology research.
