Croparium: Composite Material

This mod is designed to revolutionize the way players obtain precious materials from the "Composite Material" mod. Breaking away from traditional resource-gathering methods, this mod enables you to cultivate these rare materials just like growing ordinary crops! However, it's important to note that regular dirt farmland won't support the growth of these special crops—you'll need to create three unique types of farmland tailored to different material crops.

On Tough Farmland

For Crops of Perkin, Obsidian Steel, Echoium, Etherite, Allay Steel, and Dungeon Steel.

How to create tough farmland:

First, you need to mine specific hard stones using either a Diamond Pickaxe or a Netherite Pickaxe. The applicable stones include Obsidian, Crying Obsidian, and Deadrock (a very hard stone sourced from the "Twilight Forest" mod).
After obtaining these stones, process them to form the base of the tough farmland.
Finally, the farmland needs lava around to activate its fertility for the special crops.

On Biomass Farmland

For Crops of Ancient Fiber, Primitive Tenacity, Warden Hand, and Guardian Elder Spike.

How to create biomass farmland:

Unlike tough farmland, biomass farmland is made from soul-related blocks. You need to use a Shovel to till Soul Sand or Soul Soil—these are the core materials for this farmland type.
Similar to tough farmland, biomass farmland also requires lava to stay moist.

On Marine Farmland

For Crops of Prismarine Alloy

How to create marine farmland:

Use a Pickaxe to mine Prismarine (a common aquatic stone in Minecraft), and process it to form marine farmland.
The key requirement for marine farmland is water: it must either be adjacent to a water source or contain water itself.
