broccoli field and GHG chambers being sprayed

A crop of broccoli is sprayed in Gatton, Queensland. The greenhouse gas monitoring chambers are suited to most non-severe outdoor weather conditions.

Manual Flux Calculations

Cotton Greenhouse Gas Calculator

The Farming Enterprise Greenhouse Gas Emissions Calculator has been especially developed for use by cotton farmers.

The calculator estimates the annual farm-based emissions from a representative grains-cotton farming enterprise of 1000 ha to exceed 2000 tonnes of CO2-equivalent.

Farming Enterprise Greenhouse Gas Emissions Calculator

Farming enterprises contribute about 20% of Australia’s total greenhouse gas account. The greenhouse gas calculator has been developed to provide an estimate of farm-based emissions in Queensland.

While the calculator is based on best available information, it is not definitive. It should be used for information only, as there is an element of uncertainty associated with estimating greenhouse gas emissions from agricultural enterprises and ecosystems.


The maintenance of soil organic carbon (SOC) in terrestrial ecosystems is critical for long-term productivity.

Simulation models of SOC dynamics are valuable tools in predicting the impacts of climate on carbon storage and developing management strategies for the mitigation of greenhouse gas emissions, however, their utility is generally reduced due to need for specific data.

The SOCRATES model is a simple process based representation of SOC dynamics in terrestrial ecosystems, which requires minimal data inputs and specifically designed to examine the impact of land use and land use change on soil carbon storage. It also contains a simple yield calculator.

SOCRATES was successful in predicting SOC change at eighteen long-term crop, pasture and forestry trials from North America, Europe and Australasia. These trials ranged from 8 to 86 years in duration, over a wide range of climates and soil types.

Us Cropland Greenhouse Gas Calculator

The calculator from Michigan State University was created to help farmers, extension educators, agencies, policymakers, and others learn about greenhouse gas emissions from field crop agriculture in order to make informed decisions about crop management and environmental stewardship.
