Form Insights

In terms of volume, liquid biofertilizers dominated the seaweed fertilizers market with a share of 61.3% in 2019. This is attributed to ease of utilization and high effectiveness of the product in plant growth. Organic farming is an upcoming trend in the U.S., which has created lucrative opportunities for farmers, with the government providing subsidy-related advantages to promote such sustainable farming practices. With advancements in organic farming and gardening techniques, the importance of these fertilizers has significantly grown over the past couple of years.

Liquid seaweed products are increasingly being used due to their ease of application, wherein the liquid is added to watering systems and sprayed evenly on the plants to boost their growth, whereas utility of these fertilizer flakes are a part of routine farming practices. The powdered form of the product is incorporated into plantation systems at regular time intervals using irrigation systems for optimum results.

Furthermore, flakes or powders are increasingly gaining traction in the country due to their properties such as 100% solubility and resistance against drought, heat, and frost. In addition, their use reduces plant shock, promotes seed germination, and aids in higher nutrient uptake, which enhances the effectiveness of the applied fertilizer.

Furthermore, these seaweed flakes boost resistance to fungal attacks, insects, and aid in root development, which eventually enhances the fruiting and flowering capabilities of plants and promotes soil structure improvement by stimulating soil microorganisms. The powdered form is dissolved by stirring them with neutral water, which is thereafter applied with irrigation water or foliage spray. Additionally, post-dilution with water, powdered seaweed is applied with farm chemicals.
