Seaweed extract contains natural growth hormones such as cytokinins, auxins, and gibberellins. These hormones promote cell division and elongation, leading to faster growth and higher yields.
It also provides essential nutrients like potassium, magnesium, zinc, and iron, which are crucial for plant development.
Seaweed extracts contribute to improved soil structure and fertility. They contain polysaccharides that enhance soil aggregation and increase water retention.
Plants treated with seaweed extract show increased resistance to environmental stresses such as drought, frost, and salinity. This is partly due to the presence of betaines, which help plants manage osmotic stress.
Seaweed extract strengthens plant immunity, making them less susceptible to diseases and pests.
The use of seaweed extract can enhance the quality of crops, improving their flavor, color, and nutritional value. This is particularly important for fruits and vegetables. It also helps extend the shelf life of products.
