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

“We’re seeing yield increases there from sort of 200 to 500 kilos to the hectare AND we’ve actually reduced our urea inputs by 100 kilos to the hectare” 🐟🌾🌱

The process used to manufacture BIO MARINUS™ is an enzymatic hydrolysis of fish at low temperature. This retains the proteins, amino acids, naturally occurring vitamins, 7% to 10% fish oil (including Omega 3), and 7% to 10% hydrolysed fish bone. The addition of both seaweed, and a carbon extract of humic/fulvic acid to this blend increases beneficial bacterial and fungal activity, and plant nutrient availability of both calcium, and magnesium 🐟🦴🌱

"Because of so much worm activity it's aerating. So it's letting the moisture get away in the winter time, and holding onto the moisture in the summer time." 🪱🌱💧

"I actually think they're one of the missing links. I think the bioavailable nutrition that you get from the kelps and the fish are adding that X-factor to what I'm doing.” 🌿🐟
