We set out our territory by growing region rather than administrative map, because a feeding plan follows the crop and the soil, not a provincial boundary.
5 provinces covered
Deep red basalt soils worn down by repeated inorganic cycles, with falling pH and lost structure. This is where the high-organic lines are used most, mainly to rebuild the fine-root zone after harvest.
6 provinces covered
Closest to the Tay Ninh packing plant, so the shortest delivery loop. Perennial industrial crops and estate-scale orchards dominate, with demand weighted to scheduled root feeding around the rains.
13 provinces covered
Alluvial soils, but seasonally acid-sulphate and salt-intruded, and cropped several times a year. Organics here hold soil structure and water retention between crops, alongside humic drenches.
Dai Viet supplies a quality file per batch, trains counter staff to read labels, and sends an agronomist along when an orchard has root problems.
The province-by-province dealer list is being compiled. In the meantime, call the hotline to be pointed to the nearest dealer.
