Algae in Soil

Soil traditionally consists of 5 main components. The first (and largest) component of soil are the minerals which include a combination of sand, silt and clay, the second is water, the third is organic matter, the fourth is gas and the fifth is microorganisms. The fifth component is usually less than 1% of the soil volume but without the microorganisms like nematodes, worms, bacteria, fungi and algae the soil is considered to be dead and can severely limit plant growth. The algal biofertilizer we provide contains different species of algae for a diverse complex of microorganisms that will help your soil thrive.

There has been a huge amount of research on aquatic algae but, very little attention has been given to soil algae. The Food and Agriculture Organization of the United Nations are fully aware of the benefits of algae in soil and mention on their website that “Being photosynthetic, algae play an important part in introducing organic matter into the soil and excrete polysaccharides which increase soil aggregation.” Cyanobacteria is a general term for blue green algae; there are a huge number of different species of cyanobacteria but, many species have the ability to perform photosynthesis as well as nitrogen fixation. This ability to perform both processes is why this special group of organisms make such an excellent component of our biofertilizer!

In Soil Algae's Live Algae Soil Amendment, we use a unique combination of up to 5 species of algae; Anabaena, Chlorella, Chlamydomonas, Haematococcus and Scenedesmus. You can learn more about each species of algae that we use here.
