The Syringe Pump Gas Distribution (SPGD) system: a simple and low-cost method for simulating NH₃/¹⁵NH₃ deposition.

ABSTRACT: Ammonia (NH₃) in the atmosphere plays a crucial role in the global nitrogen cycle. Elevated NH₃ deposition can result in various detrimental ecological and environmental consequences. Traditionally, researchers have employed methods such as static fumigation, dynamic fumigation using high-precision mass flow meters or standard gas cylinders, and free air enrichment to investigate vegetation responses to NH₃ deposition. However, these approaches may suffer from inaccuracies, high costs, or technical complexity. In order to address this issue, we developed the Syringe Pump Gas Distribution (SPGD) system, a cost-effective new method for simulating NH₃/¹⁵NH₃ deposition. This system allows for precise and stable mixing of NH
