Soil Dynamics Fertiliser Seaweed Extract is a 100% soluble powder made from fresh Ascophyllum Nodosum or Norwegian Kelp. It is the best known seaweed on the planet and the most researched by science.
The benefits of using seaweed in agriculture are well known. They are packed full of plant growth hormones, amino acids, and trace elements. They aid in the uptake of nutrients into plants and act as powerful microbial stimulants to improve soil health.
A little bit, often is the best way to use Soil Dynamics Fertilisers Seaweed Extract. The aim is to use fairly low doses early and frequently in the growing season. For best results it should be used both soil applied and as a foliar spray.
The focus is to stimulate early root development via irrigated or sprayed soil drenches and to maintain overall plant vigor through foliar sprays.
It can also be used as a microbial food source in addition to biological inoculants and compost extracts.
