The farmland and grass path is not transformed into dirt when we put some water above

The farmland stays of the farmland even if we put a bucket of water above

I think that is the farmland shall owe normal future of the earth(ground) or that we can make can things above

What is to pass was that the farmland is to stay as she(it) was and that she(it) became wet

1. Take of the earth normal or of grass.
2. Cultivate with a hoe.
3. Then place a bucket of water above.
