Would increased airflow alone be able to dry soybeans in high humidity locations?
In high humidity situations you need to add some heat to lower your relative humidity so drying can progress. You need a combination of temperature and relative humidity that will create a moisture equilibrium that is at or just below the desired final storage moisture content. This is why just adding more air wont solve the problem. If it is in a tropical area, just adding heat may get the corn dried but it may need to be cooled as well to store well.
