If you didn’t already know, seaweed is one of the best plant fertilisers out there. Some coastal growers across the world have been known to harvest seaweed and use it in their gardens to enhance their crops. That’s if they are fortunate enough to be allowed to harvest seaweed from the often, privately-owned beaches.

So why is seaweed popular for gardening? Despite being different from the typical composition of most fertilisers, seaweed’s unique nutritional value works well, if not better, to encourage essential biological plant processes.

Seaweed Fertiliser vs. Other Fertiliser

The difference is that while most fertilisers are typically composed of high nitrogen, phosphorous and potassium concentrations, seaweed mainly contains potassium of these three. In place of nitrogen and phosphorous, seaweed is rich in higher concentrations of many other vitamins, minerals and enzymes that work to enhance the health and growth of plants. One of the ways seaweed improves plant health is by boosting their ability to resist various external/environmental factors that would risk their development.

How Seaweed Boosts Plant Resistance

Ascophyllum Nodosum is the most commonly used species of seaweed for agriculture. It can thrive at both very high and low temperatures, ranging from -25 degrees Celsius in winter up to 40 degrees in summer. This is because, over time, seaweed has evolved its biochemical compounds (or for better understanding, DNA) to cope with the harsh conditions of its habitat, salty sea water.

Therefore, when seaweed is extracted for fertilising purposes, it transports this ability through its nutrients onto the recipient plant. Strengthening its ability to adapt and overcome external and abiotic causes of stress and in essence, making the plant strong in resistance.

 In fact, there are 5 specific ways in which seaweed boosts plant resistance:

  1. Resistance to Frost
  2. Resistance to Pests (Aphids)
  3. Resistance to Soil Borne Diseases (Seaweed stimulates the growth of microbial fungi in soil that assists in defending plants from soil-borne diseases.)
  4. Resistance to Stress
  5. Resistance to Drought

 

If after reading all of that you’re still not convinced and want to know more about seaweed as a fertiliser, then you should read our post about the benefits of liquid seaweed fertiliser. In this guide, we go into specific detail of why seaweed is known historically for improving the health of plants.

Otherwise, if you can’t wait to get your hands on a seaweed fertiliser, we recommend Seafeed Xtra! Seafeed Xtra is a liquid fertiliser that contains a higher concentration of beneficial vitamins and minerals compared to the average seaweed fertiliser. Giving your crops even more strength and resistance to frost, pests, disease, stress and drought during periods of harsh weather or when they’re young and sensitive to their environment.
