3.5 Advantages of moist grain preservation in the sectors of labour organisation and investment costs The preservation procedure can easily be integrated into the organisation and the circumstances of the individual farm. This results in the following advantages: 1. Very high work rate during harvesting since the performance of the dosing equipment can easily be adjusted to the farm situation. 2. Low capital tie-up due to low procurement costs for dosing and screw conveyor in comparison to drying facilities. The equipment can also be used on an inter-farm basis. 3. Existing buildings can be...
