After this, they plough the ponds as soon as every week, thrice. This may help the soil lose ammonia within the type of fuel, making the ponds contemporary for the prawn tradition. Before supplying water to the ponds, they unfold substances comparable to lime, vermin compost, or natural carbon into the ponds, which assist the soil within the ponds to turn into sturdy and help in absorbing much less water.
This step is essential since in case your soil absorbs the water in a big quantity, it would regularly make water scarce for the prawns. Then the water is launched into the ponds. Soon after the water stage reaches a enough peak, you need to add Dolomite, Magnesium Sulphate, and Murate of Potash till the water attains coloration.
