About Us

Walco Seed Cleaning is a mobile on-farm operation giving farmers the best quality service.

In 2001, Kurt Walter joined up with Sanders Seed Cleaners who has been in the industry for over 30 years. Kurt and his partner Merey Colquhoun started up Walco Seed Cleaning in 2005 and created a diverse business in the seed cleaning industry within South Australia.

We have built a team of keen hard working players to service both regular and new clients.

Today they have several machines actively travelling throughout the state and even occasionally interstate to help out our farmers.

Our Services

Seed Cleaning

Seed Cleaning or Harvest Cleaning is done to value add to harvested grain. Cleaning out of spec grain to improve quality will also increase the dollar value of your grain and takes out the stress of possibily having a load rejected at the receival site.

Seed Grading

Seed Grading is the term used for getting the largest, healthiest seed suitable for sowing the next seasons crop.

Plants from larger seeds are often more vigorous, grow more quickly and produce more tillers, especially at the early stages of growth.

Seed Dressing

Farmers use large section of their home-grown seeds for next sowing. These seeds are often un-treated. Untreated seeds are prone to fungal infections, diseases and insect invasion. This can affect the overall output. Farmers often lose out the opportunity of maximizing the potential of crops because of untreated seeds. One of the best ways to get maximum returns on your efforts is by professionally applied seed dressing.
