How to check the effectiveness of the inoculation?
The best way to evaluate if the inoculantion has been successful is to carefully dig up some plants 20 days after emergency, and gently wash the roots with water. Nodules in the main root are a consequence of an early infection, usually due to the inoculation. Early infection guarantee a good nitrogen supply from the beginning of the soybean cycle. In this way, by the time the crop requires maximum nitrogen fixation, the plant will have the best quantity, location and nodule size.
