Common practices for manual greenhouse gas sampling in rice production: a literature study on sampling modalities of the closed chamber method

摘要: Rice production is a major source of global methane emissions and many studies have been conducted to quantify flux rates alongside N2O from rice fields. The closed chamber method with manual sampling the conventional approach for determining greenhouse gas (GHG) emission However, as now, there no commonly accepted standard measurement protocols, so that published encompass variety different modalities depending on specific settings labour limitations given study. This literature study comprises 155 peer-reviewed articles GHG static basis determine most common practices this regarding following features:(1) procedures (duration closure, number samples per closure replicate chambers),(2) timing (number samplings day time sampling) and(3) intervals (between two consecutive days).It has ...
