The Ravensdown co-operative has unveiled its new $30 million state-of-the-art fertiliser blending plant and distribution centre in New Plymouth today.
The company's regional manager, Mike Davey, said a feature of the facility is a $5 million precision blending plant imported from the United States.
"So you're blending the right amount of product, the right amount of nutrients, the fertilizer's then spread accurately in the exact amount that's required for that particular job."
Blending would reduce the impact of nutrients on the environment by applying the right amount of fertiliser in the right place at the right time, Mr Davey said.
The site is fully enclosed and onsite stormwater will be collected and treated to strip it of nutrients.
The new 7.5 hectare site replaces a 100-year-old plant next door and has storage capacity of 52,000 tonnes.
