The document discusses different types of legume inoculants produced by Becker Underwood, including their benefits and proper uses. BioStacked is an advanced inoculant that increases yields up to 14% more than conventional inoculants due its plant growth promoting properties. Nodulaid is a peat-based inoculant that can be applied in-furrow or with seed and is compatible with some fungicides. Nodulator granules ensure proper placement of rhizobia bacteria ahead of rains and flow smoothly during seeding. It is important to match the correct strain of inoculant to the specific legume type in order to achieve effective nitrogen fixation.

1. Why inoculate and which inoculant suits me best?
The incorporation of crop or pasture legumes, in cropping rotations or in pastures is by far the most cost effective alternative
to expensive nitrogenous fertilisers. Provided their roots have been effectively nodulated by specialised root-nodule rhizobia
bacteria - found in inoculants. The millions of rhizobia bacteria which convert nitrogen from the air into a form available to
the plant is a process known as 'nitrogen fixation'. Nitrogen-fixing rhizobia are the active ingredients in all
Becker Underwood inoculants.
BioStacked® - the latest advancement in inoculant technology
BioStacked trial results have show an average increase of up to 14% above conventional inoculants. Containing a
powerful fertiliser “Integral”, Integral is known as a plant growth promoting rhizobacterium (PGPR). The PGPR promotes
greater root and nodule biomass, faster canopy closure and higher yields. An example of ROI, seeing a yield increase from
2 to 2.2/t/ha you get a net grain gain of about 10%. An estimate crop value of $350 to $400/t, you see a winning return of an
extra $70 to $80/ha.
Nodulaid™ - peat based inoculant
Nodulaid is a reliable, self-adhering, peat based inoculant that can be applied in a slurry coating while augering seed into
the drill or by water injection in-furrow (refer table 1). Proprietary formulation with stabilisers allows tank mixing with key
fungicides (refer table 2).

The important thing to remember is that, just as there are many different types of 14 35.6 3.0

type. Put another way, each type of legume requires its own specific strain of rhizobia
to achieve effective nodulation and efficiently fix nitrogen.
