Effects of acidifiers on soil greenhouse gas emissions in calcareous soils in a semi-arid area.

ABSTRACT: In most agricultural fields, when soil pH is high, elemental sulfur or sulfuric acid are used to reduce soil pH and increase the availability of macro and micronutrients for optimum crop yield. However, how these inputs impact soil greenhouse gas emissions is unknown. This study aimed to measure the amount of greenhouse gas emissions and pH after the application of various doses of elemental sulfur (ES) and sulfuric acid (SA). Using static chambers, this study quantifies soil greenhouse gas emissions (CO₂, N₂O, and CH₄) for 12 months after the application of ES (200, 400, 600, 800, and 1000 kg ha^-1) and SA (20, 40, 60, 80 and 100 kg ha^-1) to a calcareous soil (pH 8.1) in Zanjan, Iran. Also, in order to simulate rainfed and dryland farm
