Review on the effects of biostimulants of seaweed and humic acid and some nutrients on seeding and other related traits in soybean

Natural biostimulants such as seaweed and humic acid may have positive effects on germination. Seaweed extract comprises high and low consumption elements, amino acids, plant growth regulators, and vitamins which increase root absorption and improve the quality and compounds of antioxidants. Humic acid is a mixture of sources such as soil, humus, oxidized lignite, coal and etc. Nutrients are essential for the growth and development of plants which are consumed in lower amounts. This current study was conducted to investigate the effects of biostimulants of seaweed and humic acid and some nutrients on seeding and other related traits in soybean. The current study showed that biostimulants of seaweed extract and humic acid and some nutrients had positive effects on germination.
