The heavy rains that fell in the hills around Southland have given the farmland on the plains a serious rinsing and that's not a good thing! When those of us living downstream near the coast see swedes and bales of silage floating by and can smell rotting animals in the rivers and estuaries, there's reason to be concerned. If something as big as baleage and livestock can be washed off farms, what other unseen 'stuff' has been flushed out and has entered the waterways? I'm thinking of the load of urea farmland carries, herbicides and pesticides that are commonly used along with the effluent that is being returned to the soil as part of farm management, especially on dairy farms. Heavy rain washes this off the farms and into our rivers then out to sea. It's not a healthy state of affairs.
