SGASA certification scheme simplified
The Seedling Growers Association of South Africa's (SGASA) certification scheme is based on the Australian Nursery scheme and was fine-tuned in South Africa in early 2000/2001.

Worldwide there are many quality management systems in place focusing mainly on safety and environmental issues. The system adopted by SGASA has taken a more hands-on approach concentrating on more seedling specific practices. Some seedling nurseries have found added benefit in having both ISO management systems as well as the SGASA certification scheme. These systems are constantly undergoing changes to improve them and are quite often not compatible with others.
For instance, the FSC system does not allow the use of any Agro-chemicals, yet the SGASA scheme allows for this if properly contained and governed.
Currently the Auditing officer is Kobus Serfontein from QMS Agriscience. Kobus is a trained Plant Pathologist with many years of field experience.
Nurseries in South Africa predominantly grow a range of timber, vegetable and bedding seedlings alongside one another. Section 19 in the certification scheme has been specifically implemented to govern the spread of Fusarium circinatum or Pitch Canker Fungus from seedling nurseries. All nurseries growing Pinus seedlings need to adhere to this section and will fail an audit should they not achieve a minimum of 75% compliance.
Listed below are the 20 sections nurseries are evaluated against. Section 1 has been expanded in detail as an example of the audit criteria.
Section 1: Water quality
Quantity: Is there enough water at your source to supply your nursery 365 days of the year?
Are there back-up systems in place to hold enough water for up to 48 hours?
Is there a generator present to continue watering during a power failure?
Delivery: Is delivery sufficient on the warmest, windiest day of the year?
Treatments: Is the source of water acceptable for irrigating crops? Records need to show if water contains any pathogens that need to be eradicated either by filtration or chlorination.
The PH and EC of the water needs to be monitored and corrected. All treatments need to be recorded and monitored.
Storage: How does a nursery store water? If stored in an earth dam, this water will need to be treated before entering the irrigation system. Generally, concrete reservoirs are used for storing water.
Drainage: All irrigation water needs to drain efficiently away from site. This can be done in the form of drainage canals into settling ponds. It is illegal to contaminate water sources with excessively high nitrates, therefore these must be removed before entering source water again.
