Different types of inoculants & what they are used for
Generally, there are four main categories of inoculants that are used for seeds. They are designed to protect the bacteria that are needed for them to thrive since the majority of seeds already have toxins in them that destroy Rhizobia. These are distinguished by their carriers, which include peat, freeze-dried powders, granular inoculants and a pre-coated seed form with inoculums as part of the pellet.
Peat
When using peat inoculants, the bacteria sticks directly to the peat moss. They are, at times, manufactured with a substance that allows them to stick. If they are not sticky, the farmer has the option to add this independently.
Freeze-dried powders
Powdered inoculants were introduced before the 1900s and have been the only commercial formula available for decades. They need to be mixed with water before use, which is beneficial when it comes to shipping and costs as well as storage.
Granular
Granular inoculants commonly come as little pellets and are often made of inert clay or peat. They are made up of little granules and it is this which the bacteria is applied to. This is then added to the furrow when you are planting your seeds.
Liquid based
Liquid inoculants eliminate the uneven spread of powdered inoculants. Having a mixed liquid means that you can evenly coat the seeds and be sure that they are well-treated. The liquid can be applied to the seed before it is planted, or otherwise added in when you are planting the seeds.
A pre-coated seed form
When it comes to pre-coated seed form inoculants, usually the inoculum is found as part of the pellet. A lot of companies will do this to make your job easier – the seeds arrive pre-inoculated so that you don’t have to waste any time adding the inoculant yourself.
Of these types of seed inoculant, the best one for your seeds depends on what kind you have, so make sure you know this before you buy yours. Depending on how much time you need to save and what method you prefer, each of these methods could work well for your crops.
If you are still unsure about which is the best inoculant for your crops, make sure to get in touch and our friendly team will be able to advise you based on the specifics of your plants and the environment you are growing them in.
