The smell of paddy (and also of large quantity of cooked rice) is absolutely soothing for me and it brings back memory.
During my grandfather time, it was very common for a crab to grab your fingers when you are planting the paddy. My father would chase turtles and large frogs when he was a kid.
When I was a kid, the crabs and turtles were gone but frogs were pretty abundant. In last twenty years, there are hardly any frogs left. Earthworms are also under stress.
The Japanese style of planting paddy wasn't very common in India before green revolution. Then we had a some new varieties that took over almost all old varieties for a simple reason for yield. My grandmother used to complain about a lost variety a lot. Apparently it had such a strong aroma that whole village would know what rice you have cooked. Glad to see more efforts preserving old varieties [1].
