Biostimulants and Soil Amendments Market Size, Share, Growth, Trends, and Global Industry Analysis: By Product Type (Biostimulants, Soil Amendments), By Crop Type (Cereals & Grains, Fruits & Vegetables, Oilseeds & Pulses, Turf & Ornamentals, Others), By Method (Foliar Treatment, Soil Treatment, Seed Treatment) and Region Forecast 2020-2031

Biostimulants and Soil Amendments Market size was valued at US$ 4,527.1 million in 2024 and is expected to reach US$ 10,070.7 million by 2031, growing at a significant CAGR of 12.1% from 2025-2031. Moreover, the U.S market is projected to grow at 12.4% CAGR over the forecast period. The market refers to the industry focused on products that enhance plant growth, soil fertility, and crop yield through natural or synthetic substances. Biostimulants include microbial and non-microbial inputs that stimulate natural processes to improve nutrient uptake, stress tolerance, and overall crop performance, while soil amendments consist of organic or inorganic materials added to soil to improve its physical, chemical, or biological properties.

The market is witnessing steady growth, driven by increasing demand for sustainable agricultural practices, rising awareness of soil health, and the global shift toward organic and eco-friendly farming. Farmers and agribusinesses are increasingly adopting these products to enhance productivity, reduce dependency on chemical fertilizers, and meet stringent environmental regulations. With strong support from government initiatives, technological advancements in crop management, and growing emphasis on food security, the market is expected to expand significantly across both developed and emerging regions.

Facts & Figures  

• In fact, 30%–40% of agricultural soils worldwide are estimated to be degraded, driving demand for soil amendments and biostimulants to restore fertility.
• Over 70 countries have established regulations or guidelines for biostimulants, with the EU being the most advanced in standardizing their use.
• More than 2.5 million hectares of farmland in Europe alone utilize seaweed-based biostimulants annually.
• Organic farming covers 76 million hectares globally (as of 2023), creating a strong base for biostimulant adoption.
• Up to 20% yield increase has been recorded in crops like tomatoes and grapes when biostimulants are applied under stress conditions.
• Around 60% of global fruit and vegetable farmers use some form of biostimulants or soil amendments to improve crop quality and shelf life.

Key Developments 

• In June 2025, the Indian government expanded fertilizer regulations to include biostimulants, microbial formulations, and biochemical fertilizers through the Fourth Amendment Order, 2025. This move aims to enhance crop productivity, promote sustainable farming, and provide regulatory clarity for bio-based agricultural inputs. It is expected to accelerate adoption and strengthen the biostimulants and soil amendments market in India.
• In February 2023, Mitsui & Co. Ltd. announced an agreement to acquire a stake in C&B Agri Enterprises Limited, a leading Irish biostimulants manufacturer. The partnership aims to strengthen the growth strategy for biostimulants products, leveraging CB-Agri’s expertise in natural seaweed- and marine-derived amino-acid formulations. This collaboration is expected to expand product offerings and enhance market presence in the biostimulants sector.

Biostimulants and Soil Amendments Market Segmentation

Based on the product type

• Biostimulants
• Soil Amendments

Among the product types, biostimulants are anticipated to lead the market, driven by their rising adoption in sustainable and organic farming practices. Farmers increasingly prefer microbial and non-microbial biostimulants as they enhance nutrient uptake, improve stress tolerance, and boost crop productivity without harming the environment. Unlike conventional chemical inputs, biostimulants offer long-term soil health benefits, aligning with global trends toward eco-friendly agriculture. Strong demand for organic-certified produce in regions such as Europe and North America further accelerates their use. Additionally, continuous innovations in microbial formulations and seaweed-based extracts are strengthening their dominance, making biostimulants the primary growth driver in this market.

Based on the crop type 

• Cereals & Grains
• Fruits & Vegetables
• Oilseeds & Pulses
• Turf & Ornamentals
• Others

Among the crop types, fruits and vegetables are anticipated to lead the market, owing to their higher economic value and consumer demand for residue-free, nutrient-rich produce. Farmers growing fruits and vegetables increasingly adopt biostimulants and soil amendments to improve crop quality, enhance shelf life, and boost tolerance against abiotic stresses such as drought or salinity. Since these crops are more sensitive to soil conditions and input quality, the role of organic amendments and microbial biostimulants becomes critical in maintaining productivity and profitability. Rising global consumption of fresh produce, combined with strong demand for organic fruits and vegetables, further drives this segment’s dominance.

Based on the method 

• Foliar Treatment
• Soil Treatment
• Seed Treatment

Among the application methods, foliar treatment is anticipated to lead the market, as it provides rapid and efficient nutrient absorption directly through plant leaves, resulting in quicker visible effects on growth and productivity. Farmers prefer foliar sprays for their ability to correct nutrient deficiencies, improve stress tolerance, and enhance photosynthesis during critical growth stages. This method also reduces nutrient losses compared to soil application, making it more cost-effective and environmentally sustainable. With growing demand for high-quality crops, particularly in fruits and vegetables, foliar treatment is becoming the most widely adopted application method in the biostimulants and soil amendments market.
