Fields and crop cycle
Clear only uncleared fields. Plow before planting; fertilizer and irrigation are optional boosts with their own selected costs and effects. Growth takes 1–12 normal hours depending on the crop. Ready crops deteriorate over approximately 24 hours until harvested; stored harvest never deteriorates. Multi-harvest plantings have a finite number of cycles. A paused harvest needs an explicit resume action after capacity becomes available.
Bulk work stays within one farm. Review included and excluded fields, seed requirements and exact machinery. Starting work may atomically attach an idle compatible implement to the chosen tractor. The server validates availability; it never silently substitutes machinery or buys missing resources.
