Here at DCT we have developed a range of organic and conventional products to meet the needs of New Zealand’s soils and in some cases to meet the needs of a specific farm or paddocks, soils and crops.

We strive to produce the highest quality product by developing our unique manufacturing processes and by using the best local and imported ingredients available.

Our organic products are registered with Bio Gro, New Zealand’s leading organic certifier.

In addition to nitrogen we are able to add vital trace minerals to our products when needed, saving you time and money.
