On-farm grain storage is a viable concept that has been well proven in all major grain producing countries around the world – especially where de-regulation of the grain industry has occurred.
In the USA, most grain is stored on-farm or in country elevators and in Australia a similar situation exists. The extend of on- farm storage in South Africa is not known but is increasing rapidly and has probably kept up with the increase in grain volume produced over the past 20 years since Co-operative storage has not increased significantly since the early 1980’s.
In outlining a model, the initial purpose for storing grain should be reconciled from the start with a change in this purpose ie. while it may typically be the goal to use a grain silo complex as flow-through system only in Year 1, circumstances may force a change to this goal in Year 5 and the complex layout should be flexible enough to accommodate this change. This implies immediately that the site should be suitable to accommodate such future requirements. A rule of thumb is to evaluate present needs, then add possible growth over 3-5 years, then double the volume of grain handled and re-plan for this expanded need.
