Natural mineral fertilisers offer a soil-friendly substitute to harsh, salt fertilisers. The NTS range comprises a variety of unique, activated mineral products which can deliver a similar, but more sustainable response to the chemical alternative. Often, the NTS Dry Mineral Fertilisers have been 'activated' with biological synergists or boosted with humate-based uptake enhancers. Alternatively, they have been micronised to improve their performance in the soil.
