In WA the many logistical and production benefits that ALOSCA granular legume inoculants bring to crop legume programs are well known.
ALOSCA’s granular inoculants can now also provide a cost-effective option for producers to improve underperforming pastures through incorporating the benefits of the WA-developed Group C inoculant strain for sub-clover.
Many sub-clover paddocks in WA have not had inoculant applied for many years.
These are often symptomatic of poor nitrogen fixation with root nodule colonies low in number and pale in colour as opposed to the pink nodule colour which signifies the likelihood of good nitrogen capture by the plant.
Provided common nodulation constraints such as low soil pH and herbicide carry over interference are being addressed, upgrading the sub-clover inoculant strain to improve legume content and production is the next logical step to consider.
An improved Group C strain for subclover, WSM1325, was developed in WA by the CRS at Murdoch University and tested nationally before its release by the National Rhizobium Program in 2006.
The WSM1325 strain offers improved nitrogen fixation and nodulation initiation in acidic soils over earlier Group C strains and will effectively nodulate a broader range of trifoliate clovers including the commonly grown balansa and Persian clovers.
Despite the benefits of the 2006 release many farmers are still to introduce the advantages of the newer strain into their production system.
On the inoculant application front, one of the key drivers to develop the ALOSCA dry inoculant formulation was solving the problem of how to successfully inoculate small seeded pastures species such as biserrula, bladder and gland clovers in autumn.
These species, along with the more staple species such as sub-clover and serradella, have a shallow seeding, less than 15mm, requirement and express significant production advantages when sown ahead of autumn rain.
The ALOSCA granular formulation protects the viability of the inoculant from the drying conditions during the autumn sowing window.
This makes it highly suitable not only for regular autumn sowing of small seed species but also a hand-in-glove fit for more recently developed forage establishment techniques like summer sowing of serradella and or bladder clover.
ALOSCA will be running their cashback promotion for the month of January and urges growers to contact their stockist well before the month is out to take advantage of the $100 per tonne cashback offer for their granular inoculants.

If moisture has not been limited, then nodule colonies when cut should be pink in colour and evident on the roots.
