New Inoculant Formulation Delivers More Consistent Silage

Biotal has developed a new formulation of its leading range of grass, wholecrop and maize inoculants which guarantees more consistent mixing, less sedimentation and more even application resulting in better quality silage.

“Uneven fermentation leads to patchy and variable heating, increased wastage, variable intakes and reduced performance from forage so is something to avoid,” comments Biotal Forage Products Manager Lee Gresham. “In many cases uneven fermentation can be traced back to how the inoculant has been applied and in turn to how it is mixed.

“A consistent fermentation requires an even application of inoculant onto the harvested crop, which in turn means that the inoculant must be well mixed and then held in suspension on the forage harvester,” Mr Gresham explains. “If the bacteria sediment out of suspension they fall to the bottom of the tank leading to uneven application, and in extreme cases to nozzle blockage resulting in no additive being applied. Bacteria sedimentation is a commonly reported problem according to contractors we have spoken to.

“Poor mixing and sedimentation has become a greater problem with the move to low volume products which can be difficult to dissolve, making for particular issues with Low Volume Applicators where the amount of water in which the bacteria are suspended is reduced.”

“Any new leys that were sown last autumn need checking for damage too. If the winter water table was high, the young grass plants are likely to be shallow rooted. When the cold snap came they could have been pushed out of the ground by the process of frost heave. If the land is fit to travel, the only option is to try to roll the plants back down into the soil before they die. If already dead, the affected patches will need overseeding.

“Grass leys are like a bank, if you don’t invest in them you won’t get a return. Introducing new, modern varieties this spring as full reseeds or repairing damaged areas, will produce greater yields of higher quality grass which can be used to replenish the feed-stores for next winter.”
