We can help your farm remain both environmentally and economically friendly.

Fertco organic fertiliser services include free on-farm consultation to discuss your organic farming goals and needs, comprehensive soil and plant tissue testing and the design of an organic fertiliser programme designed specifically for your farm. We also follow up regularly to ensure your expectations are being achieved.

Fertco is a one-stop organics shop, stocking New Zealand’s largest range of certified BioGro organic fertiliser products. We’ve taken all the time and difficulty out of the buying process for you, and offer a transparent quoting system with no added fees. We prefer to always support New Zealand made organic products, but where there is no comparable product we have sought quality options from overseas.

All organic fertiliser products can be supplied in bulk or packaged in 25kg, 500kg or 1000kg bags.
