Hai,
My home is situated near a paddy field with meagre cultivation. For last six years
we used to suffer from a foul smell from the water in the field.
Some of the features of the area are giving below.The smell is so suffocating.
it starts from a piece of paddy field of a small area (0.20 acre) in front of my house. From here onwards upto 400 mteres along the flow of water thru a canal, often the smell is unbearable.
At the middle of the monsoon (Sepember every year)only the smell statrs. After a few weeks, the floor along the path of flow of water( Not anywhere else),that too for about a 50-70 meters , we see some white hair like growths (perhaps some algae). Later on we can see the floor along the flow gets entirly covered with this white growth, The grass, stones etc. along the path is also get covered with this white growth. Then towards December , when the water level in the field get lower and the flow of water become very low, the area covered by white growth starts turn green and the green colour spreads. At this time onwards the smell subsides. Its seems worthy to note that the smell do not subside compltely and also that the white growths still will be there but to a lesser extent.
I have also noticed that the colour of the water has no peculiar change, eventhogh the soil below is covered with whit growth.
I hope my dear friends could suggest some valuable inputs regardig the reason for this .
