Daltons Quality Assurance Programme
___________________________________

As part of Daltons dedication to manufacturing the best products possible for the horticultural industry, a comprehensive quality assurance programme encompassing all of Daltons processes was formulated.

This programme was introduced in 1999 with the assistance of industry experts. The programme is independently audited by Hill Laboratories (Hamilton).

The programme has four basic points which accumulate to bring accountability and structure to our manufacturing process with procedures to be adhered to.

These points are listed below.

1. Conducting in-house quality tests on a regular basis complying with pre-determined testing methods. These in-house tests are, pH, EC, germination, temperature, moisture content, plant growth index, physical analysis, sieve analysis, benchmark tests, weed assays and general growing tests. Out-sourced tests are nutrient analysis, pesticide/herbicide/heavy metal residue and pest and disease.

2. Hill Laboratories audits Daltons Quality Assurance Programme every six months to verify compliance by monitoring the in-house testing methods, frequency and result compilation.

3. Engaging an independent laboratory to conduct additional tests at regular intervals. These and their frequency being determined by Daltons Limited.

4. Participating in an inter-laboratory comparative testing programme on a regular basis to establish uniformity of testing methods and results.

Every product we produce is tested and a sample stored for future reference. These checks and balances of Daltons Quality Assurance Programme are documented in a series of procedure manuals. This gives Daltons documented accountability and traceability throughout the entire manufacturing process.
