One of our customers in the North Island sent us these great examples of the mycelium fungus on the roots of his plants, which are excellent signs of a healthy and biologically active soil, thanks to use of our Liquid Fish Fertiliser 🍄🌱🐟

Healthy winter soil = a better spring garden 🌼

Bio Marinus liquid fish fertiliser naturally feeds your plants, boosts beneficial soil biology, and keeps your garden healthy and active through the colder months ❄️🌱🐟

Research shows that Bio Marinus avoids the negative effects seen in some overseas fish oil studies 🐄🌱📈

It does not impact feed intake, fibre digestion, or nitrogen losses when used to reduce methane 🌍♻️

Animal production is therefore maintained, with improved energy and protein supply helping convert more dietary nitrogen into liveweight gain 💪🥩🚜

Great to be back at the recent A&P Show Winter Feed Competition and to see such a strong turnout 👏

It was fantastic to see so many of our customers achieving outstanding results across multiple classes:
• 🥇 1st place – R**e crop
• 🥇 1st place & 🥉 3rd place – Swedes
• 🥉 3rd place – Green feed oats
• 🥇 1st place – Fodder beet

We’re especially proud that our customers also took out Overall Winner, 3rd Overall, and the Judge’s Choice Award – a huge testament to the quality of their crops and the work that goes into them.

Congratulations to everyone involved – great to see such high standards across the board! 🌱

Thank you to all the entrants, judges, sponsors, organisers and supporters of this year's Winter Feed Comp! The winners of our Ashburton comp will go through to the Mid Canterbury Grand Final later this month . . . GO ASHBURTON!

"The average across the trials we've done on farm... have been around five to ten times above the cost of application and product."

“This is striking, given that only five units of nitrogen ( N ) were applied per hectare annually, compared to the average of 190 units of N/ha on conventional farms.

This suggests regenerative systems can maintain soil health and plant growth with minimal synthetic fertiliser applications, reducing N pollution and flow-on ecological impacts." 🚜🐄🌱

IMPROVE SOIL STRUCTURE AND ENHANCE FUNGAL GROWTH WITH BIO MARINUS™🐟🌱🍄‍🟫

Bio Marinus fish fertiliser is a rich source of organic material, proteins, minerals & amino acids. It is a food source for the life within the soil (bacteria and fungi).

Mycorrhizal fungi live in symbiotic relationships with plants by colonising their root systems. Fungi develop into hyphae, which are long threads or strands that push through rocks, roots, and soil particles. In addition to extending the plant's root system, these hyphae will deepen the soil and enhance its structure. Typically, hyphae have a diameter of only a few hundredths of a millimetre. The length of a single hypha might range from a few cells to many metres. These hyphae extend the root system of the plant and will help to increase the depth of the soil and improve soil structure.

The plants will receive more nutrients from the soil through this expanded root, and the plants will supply the fungi with sugar.

Bio Marinus™ Hydrolysed Liquid Fish Fertiliser With Added Biology Bio Marinus™ is manufactured by the enzymatic hydrolysis of fish offal, blended with humate, seaweed and biology including Bacillus subtilis, Trichoderma, mycorrhizae fungi, etc. Designed to provide a high quality, cost Read More
