By applying gypsum with the lime you can apply a very high quality lime source and control the dustiness of the lime. The application will be dust free. If you have variable soils and areas with high pH you won't want to apply lime in those areas, but still may want to apply gypsum. In those situations, a mix of lime and gypsum may not be ideal.
