1. A method for determining volatility of a spray solution using an agricultural drift tunnel having a blower to generate airflow within the agricultural drift tunnel and a sprayer for projection of the spray solution within the agricultural drift tunnel, the method comprising:
causing, by the blower, a first target windspeed to be introduced into the agricultural drift tunnel during a first period of time;
projecting, by the sprayer, the spray solution during the first period of time, the spray solution having predetermined ratio of an active ingredient and a tracer;
causing, by the blower, a second target windspeed to be introduced into the agricultural drift tunnel during a second period of time, the second period of time being subsequent to the first period of time; and
determining, after the second period of time, an amount of volatilized active ingredient based on a measured ratio of active ingredient to tracer using at least one sampler disposed within the agricultural drift tunnel.
