trainers have substituted polybags in all modern tree nurseries.
Training of the root prevents root defects such as spiraling
and 'J' type root growth. Speedy germination and growth, better
survival and growth of plants on out planting are major advantages.
Lower space, potting media, labour, transport cost and cost
of pest management lead to higher productivity for nurseries.
