Abstract: A barrier grown sod production process is provided for use in growing healthy barrier grown sod on a large-scale. The process includes growing seeded growth media on a moisture impervious plastic sheet which is placed over crowned row mounds. Trenches between the row mounds may also be lined with the plastic sheet. Crowning of the row mound aids in controlled drainage of excess water, thereby keeping the ground soil dry for vehicle access and for maintaining the critical salinity/moisture content/oxygenation/fertility balance necessary for producing healthy barrier grown sod.
