Plant events

Why is there no plaint item events at all? I need to change add a random event to add seeds when a crap is havist 

if ((Math.random() * 100) <= 20) {
        if (entity instanceof EntityPlayer)
               ((EntityPlayer) entity).inventory.addItemStackToInventory(new ItemStack(mcreator_soulSeeds.block, 1));
 }

But there is no place to put it no events or anything and I tried adding it to the item code but clearly that was wrong
        @Override
        public Item getItemDropped(IBlockState state, Random rand, int fortune) {
            return new ItemStack(mcreator_babySouls.block).getItem();
        }

@Override
        public Item getItemDropped(IBlockState state, Random rand, int fortune) {      if ((Math.random() * 100) <= 20) {
                    if (entity instanceof EntityPlayer)
                         ((EntityPlayer) entity).inventory.addItemStackToInventory(new ItemStack(mcreator_soulSeeds.block, 1));
               }

            return new ItemStack(mcreator_babySouls.block).getItem();
 }       

Not getting any errors but it does not drop the seeds at all

Also there is a strange bug with the Univrisal locations of crops and plants, they spawned all over and in the sky ...
