What Rhizobium counts do I need for an economic return?
Authorities now widely recommend that in order to achieve a maximum yield benefit in large seeded legumes such as soybeans, from 100,000 to 1 million viable /effective Rhizobium cells must be applied per seed at the time of planting. This quality standard is enforced in countries requiring registration. This requirement can only be achieved through the use of sterile inoculants.
