Benefits of Baler's Choice

Bale up to 30% moisture, untreated hay is not safe to bale over 16% moisture

Effective control of bacteria and mould, stops fermentation and heating

Preservative and equipment from same manufacturer for total package and back up

Stack into your barn after baling with confidence

Higher moisture hay is more leaf retention, less tedding, higher protein, higher energy, greener hay, less time from cutting to bale, less operational cost, less weather risk

Treated hay, more milk and meat production

Quality mould and dust free, perfect for horses and livestock

Propionic acid is a natural organic acid found in the horses gut and in the rumen of all livestock

6.0pH non-corrosive on machinery, safe to handle, will not rust your baler, rain water 6.5pH

Low application rate to maximise your baling speed

Potentially an extra 30% longer baling day, start baling earlier, finish baling later

Stable will not evaporate in the bale, does not evaporate as it is sprayed onto the crop

Formulated to reduce wind drift when spraying

Formulated to stick to the crop and for even coverage



Litre for litre the strongest hay preservative on the market, typically 2-3 times stronger than other buffered propionic acids, weaker products will slow down baling speed due to high application rates, as gentile as rain water with a  6.0pH it will not corrode your baler

Baler’s Choice Hay & Straw Preservative


This product does what it says on the can; controls mould and bacteria, which stops high moisture hay from heating, totally machinery safe at 6.0pH. Now you can bale with confidence with moistures from 16% to 30% without the need of plastic shrink wrapping. The automatic applicator system is controlled through the tractor ISOBUS or baler ISOBUS connection, or through a Bluetooth connection through an antenna to an iPad or iPad Mini. This is the only accurate moisture system on the market applying Baler's Choice to within 0.1 of a litre per tonne to your baling speed and moisture changes on the go for perfect results

Baler's Choice Preservative uses propionic acid that is a uniquely buffered to a non-corrosive pH of 6.0, that is totally non-corrosive to the machinery, and the operator handles a much safer product. Citric Acid is also included, which retains crop colour, smell and "freshness"

Baler's Choice will allow the operator to gain on average 30% more output per day by starting the baling operation earlier and finishing later in the day, which is more baler productivity and profit from the operation. In a good year or dry climate approximately 20% of the hay is often spoilt or can be sub-standard due to moisture fluctuations in the crop. Most of the crop may be dry (below 16% moisture) but there will invariably be some that is not and it is the damp crop which must be treated to prevent spoilage. Moistures will fluctuate due to many factors such as high soil moisture, changes in yield and the tedding operation.  Hay baling in every climate you will see  moisture change of 5% every 6 meter along a 100 metre swath, which is common and this moisture range will be bigger if the drying operation is of poor quality, for instance, when tedding at too high of tractor speed or using a machine which is incorrectly setup.
