Rising Demand for Organic Farming & Organic Food Fuels the Growth of the Global Seaweed Fertilizers Market

According to the Population Reference Bureau (PRB), the world population is expected to reach 9.8 billion by 2050, increasing by 22% from around 8 billion in 2022. The growing population increases the food demand. Moreover, as per FAO’s projection, this rapidly growing population will increase food demand by around 70% by 2050. This growing food demand is expected to increase demand for agricultural inputs, including fertilizers, to enhance agricultural production and crop productivity.

Nowadays, chemical fertilizers are highly used to upscale agricultural production, while organic fertilizers are gaining popularity in the last few decades over the rising health consciousness among consumers. The heavy application of chemical fertilizers leads to high chemical residues in foods, which is harmful to humans and animals and is a reason for several severe diseases. Thus, as a food safety concern, consumers increasingly prefer chemical residue-free produce, resulting in the growing demand for organic foods across the globe.

Organic food reduces the risk of cancer, heart disease, stroke, allergies, obesity, and other diseases. Furthermore, several organizations are also creating awareness about the harmful effects of chemicals in food and promoting organic farming. Additionally, governments of several countries are also undertaking initiatives to support organic foods and organic cultivation. Therefore, there has been a drastic increase in the global consumption of organic food and the area under organic cultivation.

According to FIBL-IFOAM 2025, as of 2021, organic agriculture was practiced in 191 countries, with 76.4 million hectares of agricultural land managed organically by around 3.7 million farmers. In the organic farming industry, farming is governed by strict government standards. Products bearing organic labels must be produced without toxic and persistent pesticides and synthetic nitrogen fertilizers, antibiotics, synthetic hormones, and genetic engineering. Further, the global organic food and drink market reached USD 135.5 billion in 2021 from USD 65 billion in 2011 [Source: FiBL‐IFOAM‐SOEL‐ Surveys (2025)]. Such an increase in the demand for organic food is attributed to consumers’ increasing health & environmental awareness.

Organic farming involves growing crops without using synthetic fertilizers and pesticides. In organic cultivation, fertilizers such as organic fertilizers and biofertilizers, including seaweed fertilizers, enhance crop production. Seaweed fertilizers are high in organic matter, micro and macro elements, vitamins, and fatty acids. Additionally, seaweed fertilizers improve seed germination and root development and enhance plants’ resistance against pests and abiotic stress. Therefore, rising demand for organic farming and food is expected to drive the demand for seaweed fertilizers market.

Key Findings in the Seaweed Fertilizers Market Study:

In 2025, the Powder Seaweed Fertilizer Segment to Dominate the Seaweed Fertilizers Market

Based on form, the global seaweed fertilizers market is segmented into powder and liquid seaweed fertilizers. In 2025, the powder seaweed fertilizers segment is expected to account for the larger share of the global seaweed fertilizers market. The large market share of this segment is attributed to the longer shelf life, cost-effectiveness, ease of storing, and high efficiency over the liquid form seaweed fertilizers.

However, the liquid seaweed fertilizers segment is projected to register a higher CAGR during the forecast period of 2025–2032 owing to the ease of use, higher nutrient absorption compared to powder form by direct spraying, and uniform application. The liquid form allows for easy mixing and application, ensuring that plants receive a consistent and balanced supply of nutrients.

In 2025, the Foliar Spray Seaweed Fertilizer Segment to Dominate the Seaweed Fertilizers Market

Based on application mode, the seaweed fertilizers market is segmented into foliar spray and other application modes. In 2025, the foliar spray segment is expected to account for the larger share of the seaweed fertilizers market. The large share of this segment is mainly attributed to the advancement in spraying equipment and the growing need for uniform distribution of nutrients. The uniform distribution of nutrients ensures that all plant parts receive the necessary nourishment, leading to healthier and more productive plants. Foliar spray allows for the direct application of seaweed fertilizers onto the leaves, bypassing the root system and providing immediate nourishment to the plants, which is further expected to support the high growth of this market during the forecast period of 2025–2032.

The Horticulture Segment is Projected to Register the Highest CAGR During the Forecast Period of 2025–2032

Based on crop type, the seaweed fertilizers market is segmented into field crops, horticultural crops, and other crop types. The horticultural crops segment is projected to register the highest CAGR during the forecast period of 2025 – 2032 owing to the growing demand for organic fruits and vegetables and the increasing area under horticultural crop cultivation.

In 2025, the Agriculture Segment to Dominate the Seaweed Fertilizers Market

Based on end-use, the global seaweed fertilizers market is segmented into agriculture, household garden, and other end-uses. In 2025, the agriculture segment is expected to account for the largest share of the global seaweed fertilizers market. The large market share of this segment is mainly attributed to the growing organic agriculture area, the wide range of benefits of seaweed fertilizers in crop production, and growing awareness about organic fertilizers. In addition, growing farmers' acceptance of seaweed fertilizers as a viable alternative to chemical fertilizers is further expected to support the growth of this market across the globe.

However, the household garden segment is projected to register a higher CAGR during the forecast period of 2025–2032, owing to the increasing demand for organic fertilizers in gardens. Moreover, seaweed fertilizers also work against slugs and birds and prevent the growth of fungus, which is further expected to support the growth of this market during the forecast period of 2025–2032.

North America: The Dominating Regional Market

Based on geography, the seaweed fertilizers market is segmented into North America, Europe, Asia-Pacific, Latin America, and the Middle East & Africa. In 2025, North America is expected to account for the largest share of the global seaweed fertilizers market, followed by Europe, Asia-Pacific, Latin America, and the Middle East & Africa. The large share of this market is primarily attributed to the presence of key manufacturers, increasing consumer preferences for organic and natural food products, increasing areas under organic cultivation in countries including the U.S. and Canada, growing demand for biofertilizers, and growing adoption of innovative technologies in the agricultural system.
