🌊🌿From the sea to the farm, The usage of algae as biostimulants and fertilisers

💡Sea algae are a great source of organic matter for improving soil since they are rich in nutrients, natural growth hormones, and the ability to fix atmospheric nitrogen.

🚜The use of various algae presents a possible substitute for conventional fertilisers and a potential answer to the present agricultural problems.

➡️BROWN ALGAE are a rich source of nutrients like nitrogen, potassium, and phosphorus as well as trace elements like iron and manganese. Examples include Ecklonia maxima and Ascophyllum nodosum. Brown algae can increase soil fertility, boost crop productivity, and promote plant development when applied as a biofertilizer. Moreover, by promoting plant development and enhancing stress tolerance, brown algae can function as a biostimulant.

➡️RED ALGAE, like Porphyra, are also abundant in nutrients like phosphate and nitrogen. When utilised as a biofertilizer, they can increase soil fertility and plant growth.

➡️The nitrogen-rich BLUE-GREEN ALGAE, sometimes referred to as cyanobacteria, may fix atmospheric nitrogen into a form that plants can use. They are frequently employed in rice fields and other agricultural settings as biofertilizers.

➡️Blue-green algae and the water fern Azolla have symbiotic partnerships that are known as ANABAENA AZOLLA connections. Since these associations can fix atmospheric nitrogen and give the soil a supply of organic matter, they are used as biofertilizers in rice fields.

🗝️Using algae-based biostimulants, your crops can reach their full potential and become more resilient to stress and better development.
