We offer you a few simple rules and tips for application of the seed inoculation products in order to get the expected results.

• An effective inoculant must be used as instructed. 
• Seeds should be inoculated with a double dose if soybean was never grown on the intended fields. It is advisable to combine in this case two different inoculant products.
• Ideally, inoculation and sowing should take place on the same day so that only freshly inoculated seed is sown. 
• Inoculants must be stored in a cool dark place, and never above 25°C. 
• UV light kills the bacteria. All exposure of inoculant and inoculated seed to sunlight should be avoided. All work should be done in the shade. 
• Seed treated with a polymer adhesive should be stirred about 20 minutes after treatment to prevent clumping. 
• The seed drill should be clean of the residue of previous pesticide seed treatments. 
• All seed contact with chlorinated water, including chlorinated municipal drinking water, should be prevented. 
• The formation of rhizobium nodules should be checked 6 weeks after sowing. 
• If the roots have not formed any nodules before flowering, a nitrogen fertilisation of about 50 kg is highly recommended.
