Fertilizer

It is used in gardening. One unit of fertilizer is worth 100 Food Points; in other words, 3 units will fuel a 300 point Small Planter Box, 6 units will fuel a 600 point Large Planter Box, and 30 units will fuel a 3,000-point Irrigation Tower, which then fuels connected planter boxes.

One crafting recipe makes 5 Fertilizer.
