bonemeal does not work correctly

In practice, it seems that bonemeal is not working properly. The bonemeal effect cannot be applied on farmlands but seems to work only on blocks of grass, turf or sea grass. But it fails to work on crops

Steps to reproduce

Testing targets in the current behavuir

Current behavior

I tried using @selfolcation (with a radius) to apply the effect. but it only executes it on the block where I am (I think the problem is me misusing the tagert) But it doesn't work on farmlands, then I tried using @TargetBlock and in this case the bonemeal effect also works on grass blocks, but not on farmlands

Intended correct behavior

The bonemeal should also work on crops
