Soil Fertility
Till depth and compost boosts

<&soil_items>

Soil has three important values: till, moisture, and fertility. Crops only sustain properly when till reaches the maximum value of 7. Using a hoe on Soil increases till; higher-tier hoes apply more till per use.

Moisture comes from rain, nearby water, or active sprinklers. If Soil dries out and has no crop above it, it can return to dirt.

<&compost>

Right-click Soil with Compost to add fertility, up to the implemented cap. Fertility can force faster growth based on the server config. After a crop finishes a growth step on fertilized Soil, one fertility level is consumed.
