the farmer will surely grow the leguminous crops...
✔️ these crops have nitrogen fixing nodules which host the symbiotic bacteria Rhizobium which are responsible for conversion of atmospheric nitrogen into ammonia. hence replenish the amount of nitrogen in soil....
flushing the field with water will make it more nutrient deficient ,
burning is also not a good method ,
nitrogen is a gas and hence will return to atmosphere , so flushing will also not help
hope it helps !! ❤️✌️
