MOBILE SEED PROCESSING FAQs

Mobile seed processing allows you to clean, grade, and treat your harvested seed at the point of storage, saving time and transportation costs. It gives full traceability, better control over seed quality, and potential cost savings of up to 60% compared to buying certified seed.
Our mobile units are designed to handle a range of crops including cereals (wheat, barley, oats), oilseed rape, peas, beans, linseed, and some organic crops. Each unit is tailored for crop-specific efficiency and cleanliness.
Our machines use a combination of sieves, air separation, gravity tables, and optional colour sorting to remove impurities like weed seeds, small grains, and contaminants. The result is a clean, uniform seed lot ready for storage or drilling.
Yes, we offer a wide range of professional seed treatments including fungicides, insecticides, and trace elements. These are applied precisely using calibrated equipment, ensuring full seed coverage and compliance with regulations.
Processing capacity varies based on crop type and condition, but our units typically handle between 10–30 tonnes per hour. This allows most jobs to be completed within a day, depending on volume and accessibility.

On-site dressing ensures seed remains under your control throughout the process. It reduces the risk of cross-contamination, improves logistics, and allows immediate storage or drilling of the treated seed.

Absolutely. Farm-saved seed, when professionally cleaned and treated, is significantly cheaper than purchasing new seed. With proper processing, yields and performance remain comparable while input costs are lowered.

We’ll ask for crop type, estimated tonnage, and access information. Ideally, seed should be dry and stored in a clean area. Our team will advise on best practices before we arrive to ensure smooth and efficient processing.

Yes, we are experienced in working with organic growers. We use dedicated, cleaned-down equipment and follow strict protocols to avoid contamination, ensuring compliance with organic standards.

FAQs

Mobile seed processing is an alternative to buying in certified seed as your seed stock for the following crop.  Also known as farm saved or home saved seed; you use some of the grain you have produced, we grade and process it, apply the seed treatment of your choice and leave it in 500kg or 1000kg bags ready for sowing.  You will benefit from the following:

  • Seed will be on farm when you need it.
  • Big cost saving.
  • High quality seed of a known origin with no scope to be buying in problems
  • Improved cash flow as you will not have to purchase the grain element of your seed, you already own it!!
  • You are in control of a process that is happening on your farm to your standards.

Seed will grow unless it has been negatively impacted by pre-harvest glyphosate, drying at too high a temperature (Do not exceed 50°C air temp) and poor storage and handling.  A germination and vigour test will qualify suitability and eliminate doubt.  High levels of admixture can also be prohibitive, but our cleaning process generally allows you to save most standards of sample. Consider the following:

  • Germination
  • Moisture content
  • Grain condition
  • Admixture


If unsure, please contact Evans & Pearce for advice before booking.

Cleaning to a high standard will inevitably create losses, and we would expect to screen out 5-20% of the sample so make an allowance for this when setting aside your grain destined for seed.  The great thing about farm saving is you are not financially constrained by how hard we grade the seed; the rejects go back in the store for feeding or sale.

While farm-saved seed can offer a host of benefits please consider the following:

  • If you are planning not to chemically treat the seed, make sure you have had it disease tested.  Saving grain with high levels of seed borne disease will exacerbate the problem and compromise yields
  • If you are in doubt regards germination, vigour and admixture speak to us
  • You will need to pay a royalty either through us by the tonne or directly to the BSPB by the area sown.


To minimise these risks, you need proper storage, thorough cleaning, and effective seed treatment.

To ensure an efficient process, you should:

  • Provide a clear, level and accessible working area for the unit.
  • Trailers are clean, able to tip, capable of a safe coupling to the tractor and have a working discharge spout.
  • Member of staff available to operate telescopic loader.
  • Provide our operator with a clear list of amounts and seed treatments required.
  • No but tea and coffee are always welcome.
  • A homemade cake can see effort levels reach unprecedented highs!!
  • A targeted low dose method of controlling seed and soil borne diseases.
  • Some diseases like bunt or loose smut can only be controlled by a seed treatment.
  • Testing seed for the presence of disease doesn’t eliminate the threat posed by soil borne diseases.
  • While not always necessary, treatments are an insurance against establishment risks and ensure your crop gets off to the best possible start.
  • Adding a nutrient package to your seed such as Kick Of can improve establishment, plant health and resilience and yield

Why wouldn’t it? Farm-saved seed can perform just as well if it is:

  • From a healthy seed stock.
  • Properly cleaned and treated by professionals.
  • Stored correctly before drilling
  • I may need to pay a royalty to legally save and replant seed.
  • I cannot sell my farm-saved seed to another farmer.
  • I cannot farm save a hybrid variety.


Evans & Pearce can provide guidance on compliance and reporting.

While it is best to use processed seed within the same season, I can store it longer if:

  • It is kept dry and cool in well-ventilated conditions.
  • It is protected from pests and rodents.


I should re-test germination rates before planting if stored beyond the intended season.

I should consider:

  • Cost savings – Is it cheaper than buying certified seed?
  • Seed quality – Is my grain fit for purpose and suitable to be used as seed.
  • Storage and handling – Do I have a suitable area for processing and storing seed?
  • Legal requirements – Am I compliant with variety restrictions.
  • If I have doubts, I can contact Evans & Pearce for advice on whether my seed is suitable.
  • It’s in their interest to make the whole process as seamless as possible, they want to come back.
  • Experienced operators will smooth the process for the uninitiated.
  • Good communications and a site visit prior to the processing plant’s arrival are the standard.
