When you use a watering bucket to water crops it destroys the bucket but I think a huge QoL change would be to return the empty bucket instead of fully destroying it.
You have to still refill it which is fine, but having to make new fertilizer + buckets -> fill + process the crop between harvests does not feel great.
Especially when you get farther and are using hundreds of buckets in one round of crops
From a lore/logic perspective too, you're just using the water IN the bucket to water the crops not burying the full bucket in the soil
