Rice Sustainability Verification Short Course
Know what you're buying!
11 & 12 January 2024 - Jonesboro, AR
Rice Harvest and Yield
- To discuss basics of harvesting rice, yield monitor calibration, and issue of which area to use when calculating yields.
- Basic milling terms and related calculations and equation used to adjust from one grain moisture content to another.
- Theoretical (physiologic) limits to rice yield. “Is this number a typo??”
- To allow questions that you might have been hesitant to ask in other settings.
Irrigation Water Management (IWM)
- To provide an overview of irrigation units, calculations, how to make accurate irrigation measurements, how to estimate flooded areas in AWD and furrow-irrigated fields, and related issues.
- To allow questions that you might have been hesitant to ask in other settings.
- To help you to learn from our mistakes.
Greenhouse Gas Measurement & Management
- Improve understanding GHG basic knowledge,key drivers and metrics.
- Learn common methods use in GHG measurements, applications, and limitations.
- Identify cropping practices that mitigate GHG emissions.
- Review current estimates in US rice fields.
- Provide hands-on training on GHG and GWP unit conversions.
- Allow questions that you might have been hesitant to ask in other settings.
