The package contains data on soil mineral nitrogen and N2O levels measured over 70 days.

Incubation Study Soil was incubated at controlled moisture content (60 and 85% Water filled pore space) for 70 days. Soil was extracted on a regular basis for measurement of mineral N (ammonium and nitrate). Gas samples were collected periodically for N2O with a flux of N2O emission determined for each sample time using a dynamic flow system.

Skalar SAN++ Segmented flow analyser Agilent GC 7860 for CO2 (TCD), N2O (ECD) and CH4 (FID) Study was conducted over 4 months using replicate (3) samples for each sample time. Each incubation study ran for 70 days. Treatments were randomly assigned to each vial. Each sample extracted was a complete vial sample and 3 repliactes were used at each sample collection time Nitrous Oxide Research Program 1287716061357 Principal Investigator 1287715838119 Principal Investigator DAFF/GRDC
