Should I Inoculate Soybeans?

Sandy soils and droughts in years when soybeans are not being grown also can lower bacteria populations. Increasing number of years since soybeans were last planted. Most university guidelines suggest inoculating if it has been more than three to five years since soybeans were last grown in the field.

Will soybeans grow without inoculant?

Soil types with high organic matter with soybeans as a rotation crop may not need inoculants. However, in soils with low organic matter, and higher sand levels, inoculants may increase soybean yields and add nitrogen to the soil for the following crop.

Why is inoculation important in soybean production?

Careful seed or soil inoculation is required so that the developing plant root is colonised by this bacterium. If properly inoculated, biological nitrogen fixation (BNF) in soy can fully cover the nitrogen fertiliser needs of the crop.
