Commercial Seaweed Products as Biostimulants in Horticulture

Abstract

Many scientific experiments have shown that seaweed products can improve and enhance various aspects of plant growth and development. Of interest is the specificity of different plants to the concentration and mode of seaweed application. This review examines the modem day application of commercial seaweed products in horticulture. Included in the text is a comprehensive table listing a wide range of plants known to benefit from seaweed treatment. Areas of seaweed application that are of particular importance to the horticulturist are discussed in detail. While seaweed products have meat potential for horticultural practices, it would appear that they are being underutilized. Although the reason for this is unclear, a better knowledge of seaweed application will hopefully increase their usage.
