Wesley Haun, agronomist with H.J. Baker & Bro., discusses what farmers might see happen to their soybean crop if the plants are deficient in sulfur. He also explains the factors that influence the availability of sulfur in soil, as well as critical points about the sulfur uptake process. ISA would like to thank H.J. Baker for sponsoring this webinar.
Sulfur is a secondary nutrient for soybeans. It is involved in metabolic functions for the plant, including seed formation and photosynthesis.
Deficiencies of sulfur in soybeans can lead to decreased yield and decreased protein content.
Two ways to diagnose a deficiency is to perform a plant tissue analysis or to do a soil test.
Factors that impact soil-sulfur availability include:
The Illinois Soybean Association (ISA) checkoff and membership programs represent more than 43,000 soybean farmers in Illinois. The checkoff funds market development and utilization efforts while the membership program supports the government relations interests of Illinois soybean farmers at the local, state, and national level, through the Illinois Soybean Growers (ISG). ISA upholds the interests of Illinois soybean producers through promotion, advocacy, and education with the vision of becoming a market leader in sustainable soybean production and profitability.
