This photo shows the liming of a fish pond in Bangladesh. After the de weeding and repairing the dikes and bottom of the pond, liming is considered the next important work for pond preparation. Farmers usually use calcium carbonate (CaCo3 as solid limestone. Before its use, limestone needs to be sink in an earthen, cemented or metallic tank for dilution. The application dose is normally 250 kilogram/ha.

Note: We decided not to watermark the photos in order not to upset its clarity. However, we trust you will notify us if you wish to use a picture or more. This is expected and will be appreciated.
