What Is It?

Our Organic Liquid Kelp is derived from 100% Natural Australian Bull Kelp (Australian Durvillaea Potatorum), containing high concentrations of beneficial trace elements, minerals, alginic acid, amino acids and a wide variety of complex organic compounds.

Application of liquid kelp has been shown to improve soil structure and aeration, which increases plant respiration and nutrient absorption ability, while also improving disease resistance and soil water holding capacity, resulting in increased yields and plant resilience.

“I applied Microstart's Soil Fungi Mix in April; finding a single snail in the treated area was difficult by early July.
When we harvested in the following January we couldn't find a single one, while untreated crops were still heavily impacted.”
