How is the quality of terracult’s peat and substrates guaranteed?

Terracult has defined uniform guidelines for the quality assurance of its peat products and peat substrates in cooperation with the independent consultancy firm Horticon. The guidelines correspond with today’s general guidelines of the Gütegemeinschaft für Substrate und Torf (Quality Assurance Association Growing Media for Plant Cultivation).

For each of our products we have a main data sheet that identifies the characteristics, the mixture and the quality criteria. The data of the respective batch is recorded onto a measurement data sheet. By comparing these measurements with the values next to them (the tolerance range) mistakes or deviations can be recognized immediately. For every batch, the pH, EC value, granulation and dimensional weight are measured and documented in the laboratory. The measurement of the fraction, as is the case for peat products, is an important indicator for the physical quality characteristics.

In addition to controlling the quality of the harvest and its weather-induced changes, the respective batch is inspected, particularly for compliance with the norms (sub-grain and over-grain). In order to be able to analyze a possible defect or mistake at a later date, when the product is already with the customer, every packing unit gets a corresponding declaration. In connection with the delivery note, the manufacturer as well as the delivery and production dates can therefore be found out easily at any time.
