Pasture Health and Nutrition | AgriSea NZ

Productive pasture is the foundation of profitable livestock farming. This page brings together practical guidance, research insights, and supporting resources to help you maximise your pasture's performance using AgriSea's proven seaweed-based solutions.

AgriSea's pasture solutions harness the natural power of New Zealand brown kelp and ocean minerals to strengthen pasture performance from root to leaf. Rich in minerals, trace elements and bioactive compounds, they support root development, nutrient uptake and vigorous growth, helping build denser pasture with improved feed quality to support stronger stock performance.

By enhancing photosynthetic activity and plant metabolism, AgriSea products lift dry matter production and improve metabolisable energy, protein and fibre content. This whole-system support helps maintain pasture quality under pressure from weather, pests and disease, strengthening resilience while maximising productivity from every hectare.

AgriSea pasture products are safe, non-toxic, and suitable for all pasture types including intensive dairy pastures, sheep and beef grazing systems, and hill country.

Finding the sweet spot: how Chris Parry grew production with fewer cows

Most farmers add cows to increase production. Chris Parry did the opposite, and it worked. He cut cow numbers from 285 to 228 and still lifted production from 71,000 to over 100,000 kilograms of milksolids. It wasn't about chasing more inputs or pushing the farm harder. For Chris, the real shift began when he started paying attention to what was happening beneath the surface — in the soil.

Wilith Farm: From Struggle to Regenerative Success

After 3-4 years of struggling with conventional farming methods, Miah and Jenny Smith transformed their Atiamuri dairy farm. Learning from Australian soil scientist Dr. Christine Jones, they cut synthetic inputs and built soil biology. Eleven seasons later, they hosted Dr. Jones and 100 farmers to showcase their thriving operation.

Finding the sweet spot: how Chris Parry grew production with fewer cows

Chris Parry's dairy farm demonstrates that more cows doesn't always mean more profit. By focusing on soil health and pasture quality with AgriSea, he increased per-cow production while reducing herd size, cutting costs and improving farm sustainability.
