Waikaitu Liquid Seaweed.


SEAWEED BASED REFINED CONCENTRATED BIOSTIMULANT                                        

Waikaitu uses 100% wild harvested and processed seaweed to create completely natural foliar biostimulant and soil conditioner. NZBioActiveTM  is extracted exclusively from brown algae Undaria Pinnatifida which is classified as invasive seaweed. This makes it one of the most effective and ecologically responsible organic plant nutrient suspensions available. It has a stimulative effect on plants, especially during early growth and periods of stress such as drought, heat, pest pressure or frost. It stimulates cell division, root formation and improves fruit size. It is also indicated for use to lessen transplant stress. International research confirms usefulness of brown seaweed like Undaria in improving soil microbial activity which leads directly to better plant health.

Waikaitu NZBioActiveTM Topsoil Activator comes in liquid form and can be used both for root and foliar application. It can also be added to irrigation systems for ease of application.
