As a block may contain multiple soils and irrigation, it could be defined as land used for a common purpose and managed in a similar way. Larger blocks provide the model with more flexibility in averaging out the usage of the block. Due to this when deciding on blocks, try to combine paddocks and only separate on soils and irrigation where it is significant to the area being modelled. When dividing a farm into blocks, each block should:
• Grow the same pasture/fruit or crop
• Support similar animals
• Have similar climate
• Have similar topography (for pastural blocks)
• Have similar fertiliser applied
• Have the same drainage
