How AgriSea Can Help

Increase Nutrient Efficiency

Reduce reliance on inputs by strengthening root systems and activating your soil biome to unlock bound minerals, capture applied fertiliser, and enhance utilisation.

Improve Soil Function

Build organic matter, topsoil and long-term soil resilience while enhancing soil structure for better aeration and water infiltration.

Better Pasture

Fuel your stock with healthier, nutrient dense pasture that's proven to increase animal performance and long-term resilience.

Healthier Animals

Protect your cows by improving immune function to reduce mastitis, somatic cell counts and vet bills.

Better Feed Conversion

Get the most out of your pastures and feed supplements with better rumen function in your cows and calves.

Calf Vitality

Significantly increase weight gain and decrease disease threat to wean earlier, maximise returns and protect future production.

Testing and Analysis

Comprehensive testing covering biological, chemical and physical properties will make sure the best solutions are recommended for your specific operation.

Environmental Sustainability

Reduce your farm's footprint by reducing emissions, nitrate leaching and nutrient runoff with tailored programmes.

What Dairy Farmers Are Saying

"The soil's got bounce and life to it. You dig down and find worms everywhere, that never used to happen."

Chris Parry

Whangamatā

Dairy Farmer

"AgriSea has provided that missing link; I'm producing more with less, improving my soils, and doing right by the environment - and I wouldn't go back."

Matt Rout

Waikato

Dairy Farmer

"Since converting, our facial eczema spore count levels dropped from 350,000 down to 15,000, even when counts in the district were up to 500,000."

Nick & Jo Collins

Piopio

Dairy Farmers

"Everyone in our discussion group who had either no (or only mild cases) of grass staggers, the common denominator was the use of seaweed."

Ray & Jenny Ridings

Hauraki

Dairy Farmers

"Since using AgriSea we've noticed a dramatic drop in somatic cell counts, getting as low as 93,000 whereas before we were always up over 300,000."

Nathan Gardner

Northland

Dairy Farmer

"The grass is like carpet now and the cows are in such great condition. While I had to assist nearly every calving in our first season, now it's all pretty hands-off."

Stefan Van Oorschot

Northland

Dairy Farmer

"I've stopped all the artificial minerals I'd buy because AgriSea has vastly improved the overall health of my herd... I don't need them."

Dairy Farming Case Study

CASE STUDY

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 milk solids. 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.

How Does AgriSea Work?

Success starts beneath the surface. By nourishing your soil biome and natural nutrient cycles, AgriSea products will enhance your soil function, organic matter and water-holding capacity. This improves fertiliser efficiency, reduces reliance on synthetic inputs, and will help your soil withstand extreme weather conditions and recover quickly.

AgriSea products are carefully cold-brewed in batches that can be traced to their source. They retain the full spectrum of nutrients from our seaweed and other natural inputs to deliver optimal results, and many are BioGro Organic Certified.

That vitality flows through to your pasture and herd. Healthy, biologically active soils grow resilient, nutrient-rich grass that fuels animal health, fertility and performance.

With products crafted to deliver proven results and backed by rigorous science, AgriSea empowers dairy farmers worldwide to create thriving, productive systems that perform season after season, strengthening profitability while supporting the long-term health of the land and animals in your care.

Frequently asked questions

Yes. We partner with leading research organisations including the University of Auckland, University of Waikato, Lincoln University, AgResearch and The Bioscience Economy Institute to test and verify the validity of our products on dairy farms like yours. We have numerous trials and case studies available to back up every product claim we make. Many of these resources are available on our website, and our Area Field Consultants are happy to provide any further information or evidence you wish to see. Just ask.

AgriSea biostimulants support pasture development, allowing plants to grow stronger, deeper roots. This helps breaks up the soil and creates pathways for air and water to flow properly. It also increases earthworms and microbial activity underground which results in better soil structure. In times of stress such as drought, your pasture will cope better and be more resilient. Deeper roots also result in less pulling so your paddocks can withstand grazing pressure.

AgriSea manufactures a wide range of products that use a variety of natural ingredients including seaweed, fish and other organic matter that will supercharge your soil and pasture growth for a healthier herd and better productivity. Each farm and each paddock is unique, so we offer on-farm consultations to determine the best biostimulants for you. Our Area Field Consultants can conduct soil tests, visual soil assessments and herbage tests and provide a tailored plan for your dairy farm to get the best possible results.

Yes. By supporting liver function and overall livestock health, AgriSea biostimulants can help animals better cope with disease challenges. It also helps by supporting pasture quality and the soil biome (including decomposer organisms and earthworms) which can help break down pasture litter, reducing the habitat where pathogens can build up.

Most definitely. Our extensive research trials show that cows conceive quicker, gain weight faster, and are less prone to disease and illness such as mastitis, scours, grass staggers, facial eczema and more. AgriSea's range of animal nutrition products support rumen function, strengthen immunity and help cows absorb more nutrients. As a result, your cows will produce more milk and cost less to care for. Results are maximised when our feed additives are combined with our biostimulant products for soil health and pasture growth.

Yes. AgriSea's liquid biostimulants are generally compatible with most herbicides and can even help crops recover more quickly from application stress. However, because chemical formulations vary, always prioritise the instructions on the herbicide label regarding tank-mixing. For new or untested combinations, we recommend performing a simple jar test first to ensure physical compatibility before large-scale application.

There are no withholding periods if you are only using AgriSea products. There may be withholding periods if used in conjunction with other chemicals and these should be adhered to.
