Kelp Fertilizer Mod (1.21.8, 1.20.1) – Use Kelp as an Organic Crop Booster

Kelp Fertilizer Mod (1.21.8, 1.20.1) transforms kelp into a useful and natural fertilizer alternative to bone meal. In real life, seaweed like kelp is rich in nutrients due to its ability to filter seawater, making it an excellent organic fertilizer. This mod brings that logic into Minecraft by allowing players to use kelp to grow crops instantly, adding a realistic and eco-friendly twist to farming.

Instead of relying solely on bone meal, players can now use kelp for the same purpose simply right-click on crops with kelp in hand to trigger instant growth. The mod also supports automation, allowing kelp to be dispensed via redstone dispensers just like bone meal, making it ideal for advanced farming setups or redstone-powered crop farms.

Whether you want to reduce your dependence on skeleton farms, promote underwater farming, or add new value to kelp as a resource, this mod offers a practical and immersive solution.
