Place next to a field or within a field to boost yield. Find it in Store > Placeable Generators > Tile Riser.
Yield boost is very slight for added realism.
A field tile riser is a component used in agricultural drainage systems to improve water management within a field. It consists of a vertical pipe, typically made of PVC or other durable materials, that connects directly to subsurface drainage tiles. These risers are installed in low-lying or poorly drained areas of a field and serve as inlets for surface water to enter the drainage tile system.
