Abstract

The project will quantify year-round greenhouse gas (GHG) emissions, water and nutrient fluxes in irrigated, broad-acre cropping systems of the Southern Murray Darling Basin (SMDB). Current and emerging irrigation and fertiliser management practices with and without chemical inhibitors to mitigate GHG emissions from irrigated cereal rotations will be compared. Fluxes will be monitored using automated chambers over crops in weighing lysimeters. The equipment enables replicated manipulation of water and nutrients in undisturbed soil columns beyond what is possible in the field. It also allows direct measurement of nitrous oxide (N2O) surface emissions, N2O fate and sources throughout the soil profile and indirect N2O emissions in leachates. The project will develop a suite of coincident water-nitrogen-GHG-crop, empirically measured datasets. The datasets will be made available for model framework development for predicting GHG emissions in grain cultivation and for mitigation strategy development.

Methods Info
Step 1:
Description:
Automated Greenhouse Gas-Weighing Lysimeter System
A set of weighing lysimeters (32 soil monoliths in total) will be 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 of carbon 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.
Instrument(s):
  • Weighing Lysimeters.
  • Gas Chromatograph.
Sampling Area And Frequency:

Summer Cropping Season: Mid December-Mid May

Sampling Description:

One soil type - Red Brown Earth x 4 treatments x 3 replicates. Treatment 1: Bare Soil Treatment 2: Bare soil + fertilizer - 2 applications x 65 kg/ha of urea Treatment 3: Wheat Stubble Treatment 4: Soybeans sown into wheat stubble. Irrigation to meet soy bean requirement.
