Resumen
Descripción
Abstract: The autors believe that dryout periods likely destroy most organisms in pond bettons, and liming of the entire botton area shoud be done only to neutralize soil acidity and increase pH for organic matter decomposition by soil microorganisms. Use of hydrated lime for disinfection should be reserved to particularly wet parts of pond bottons. When applying liming materials, it is important to spread them uniformly over moist soil - typically within two days after ponds are drained to assure dissolution.
