Compost (bat bone meal)

So you bring poisonous potato and feed it to a bat. The bat will start getting damged till it dies with a 90% chance of dropping a bat bone. Bat bones can be crafted into bat bone meal which is used on dirt block to make it a fertilized dirt block. Once a dirt block is fertilized it grow crops such as wheat,potato,etc. 50% faster than normal. Conclusion:I think this feature will give a use for both bats and poisonous potato while improving the overall Minecraft farming experience.
