Abstract

This data package describes a replicated study comparing N2O emissions from plant-water-soil scenarios, typical of Summer broadacre cropping systems (soybeans) in the irrigated areas of the Riverine Plane in the Southern Murray Darling Basin, Australia. The methodology involves a large weighing lysimeter facility fitted with automated greenhouse gas chambers for comprehensive determination of water balance, direct gas fluxes and nitrogen and carbon in leachates. The experiment was designed to i) obtain relationships between soil moisture wet-dry cycles and N2O emissions (with and without fertilizer application) for improved calibration of computer models developed to predict soil N2O emissions at a national level. ii) Compare N2O fluxes from a wheat stubble treatment with a soy beans sown into wheat stubble treatment, keeping irrigation constant, to better quantify direct N2O fluxes from an irrigated Summer legume crop.

Methods Info
Step 1:
Description:
Automated Greenhouse Gas-Weighing Lysimeter System
A set of weighing lysimeters (12 soil monoliths in total) have been used to investigate relationships between greenhouse gas (GHG) fluxes and nutrient and water management in irrigated cropping systems. Twelve lysimeters (0.7 m diameter and 1.5 m deep) are weighing allowing replicated soil-water-plant-nutrient experimental design.Twelve automatic chambers connected to a gas chromatograph (GC) for measuring nitrous oxide (N2O) and methane (CH4) flux from the soil surface within the chambers and an infrared analyser (LI-COR, USA) for measuring fluxes ofcarbon dioxide (CO2) will be connected to the twelve weighing silos.The chamber/GHG system is operated through a computer-controlled manifold programmed to measure GHG concentration at three minute intervals in a cycle through four chambers while they are closed for a one hour period. The one hour cycle is then repeated for the remaining two sets of four chambers.Each lysimeter is mounted on load cells for constant measurement of water balance and the soil profile is monitored for volumetric water content (?v) and temperature in 10 cm intervals.
