soybean inoculant Nodulest 10 is prepared by mixing
a pure culture with sterilized Sphagnum peat moss. The
high quality of the product is obtained using a pure medium
with a very high concentration of an efficient strain
of Bradyrhizobium japonicum per milliliter (>20,000,000,000
per ml). Due to this high concentration, a small quantity
of carrier (peat moss) is used per bushel of soybean seed.
This characteristic allows Nodulest 10 to keep the
advantages of a Sphagnum peat moss based product along with
the lesser risk of blockage of seeders together with the
simplicity of use of a liquid inoculant.
to use Nodulest 10?
Using a clean plastic pot, dissolve the content of one plastic
bag of Nodulest S1 + S2 (adhesive and additive) in 2 galons
(7.5 litres) of fresh water (hypochlorite free). Mix until obtaining
an homogeneous solution.
Add the content of one plastic bag of Nodulest 10 inoculant
into the dissolved adhesive and additive. Mix gently until getting
an homogeneous formulation.
Use 7 fl oz (approx.200 ml) of the obtained suspension to inoculate
approx. one bushel (60 lbs = 1.2 units) seeds. Make sure that
the product is uniformly distributed on the seeds.
The complete preparation should be enough for the inoculation
of 50 bushels (3.000 lbs = 60 units) of soybean seeds.
in double doses
fields with no history of soybean cultivation it is advisable
the use of Nodulest 10 in double amount during the first
application. For those cases prepare the inoculant as described
above but using 2 bags of Nodulest 10. (**do
not change the amounts of adhesive, additive and water**).
fungicides have been used with Nodulest 10 (Biagro 10 in Argentina).
However, most fungicide treatments reduce bacterial survival
to some extent. Serious effects of certain products on both
rhizobia and seed viability have been observed. The performance
of new fungicides should be evaluated prior to massive inoculation.
Depending on fungicide compatibility, an increase in the amount
of inoculant/seed may be necessary to achieve appropriate numbers
of viable bacteria/seed.
