Fertilizer accelerates IC2 crop growth on Crop Sticks; crafted from one Scrap plus one Bone Meal in Industrial Craft 2.
Guide
Power a Recycler with EU and feed it junk items such as cobblestone, dirt, or rotten flesh. About 1 in 8 inputs returns one Scrap, which is the limiting reagent for Fertilizer.
Place 1 Scrap and 1 Bone Meal anywhere on the crafting grid (shapeless recipe). The output is 1 Fertilizer per craft, stackable up to 64.
Place at least two Crop Sticks on tilled dirt to form a tile, then right-click with an IC2 seed bag to plant Wheat-IC2, Hops, Stickreed, or another supported crop.
Hold Fertilizer and right-click on the Crop Stick tile. One item is consumed and the tile's nutrient value goes up, which raises the chance of a growth tick on each random update.
Use a Hydration Cell on the same tile to raise hydration, and apply Weed-EX nearby to suppress weeds. With all three boosters active, even high-tier crops like Redwheat and Stickreed mature noticeably faster.
Combine 1 Scrap with 1 Bone Meal anywhere on the crafting grid. Scrap is produced by feeding junk items into a Recycler powered by EU.
No. IC2 Fertilizer only works on IC2 crops planted on Crop Sticks. For vanilla wheat, carrots, melons and potatoes use ordinary vanilla Bone Meal.
Any IC2 crop on Crop Sticks: Wheat-IC2, Hops, Ferru, Aurelia, Stickreed, Coffee, Redwheat, and any hybrid you breed via the IC2 crossbreeding system.
Bone Meal forces instant growth ticks on vanilla plants. IC2 Fertilizer instead raises the nutrient value of a Crop Stick tile, increasing the probability that random ticks succeed for IC2 crops only.
Yes, and you should. The three boosters cover different stats — nutrients, hydration, weed risk — and stacking all three is the standard way to push high-tier IC2 crops like Stickreed and Redwheat to full maturity.
IC2 Experimental ships it for Minecraft 1.6.4 through 1.12.2, and IC2 Classic ports cover 1.7.10, 1.10.2, 1.12.2 and 1.19.2 with the same item.
