Tallgrass Solution has developed a streamlined version of passive samplers to measure nitrogen losses to ammonia volatilization after fertilizer applications. Previous studies indicate that that up to 30% of the nitrogen applied by farmers could be lost to the atmosphere through ammonia volatilization, thus, minimizing these losses can have a substantial impaction on farmer’s profitability.
The ammonia samplers are used to investigate how different timing and application methods could minimize ammonia losses increasing the amount of nitrogen available for crops. To accomplish this, a well-established micrometeorological method called the integrated horizontal flux approach is used to quantify ammonia emission rates by placing ammonia samplers at different heights over the fertilized area.

These samplers do not require an external power source and are capable of turning with the wind direction to keep a constant air flow inside the sampler. A sophisticated set of coils inside the samplers is treated with an acid solution so that it ‘captures’ the ammonia as the air passes through the device. The mass of NH3 accumulated in the sampler can then be used to estimate the flux rate over the plot during giving period of time.
The samplers and brackets are produced in batches of 30 units and come shipped in a hard case for ease of transportation to the field.
Part Number: T-101
Price: $795/sampler (30 samplers/case)
