This automatic fertiliser mixer can be controlled and has the fertiliser quality checked from the laboratory and equipped with tracing systems. Once the sack has been loaded, the data will be recorded on QR Code which specifies the location, date, time of production and proportion of raw materials of fertiliser in the sack, including buyer information (if any). This allows traceability for information on the production of fertiliser in each sack and nutrient content that builds confidence of buyers.
