dc.description.abstract | Vital information aquaculturists need to know on lime are: (a) what lime to use; (b) why lime is used; (c) which form to apply; (d) how much to apply; and (e) when to apply. Experiments on the use of lime in brackishwater ponds at SEAFDEC Leganes Research Station pointed out the need to apply lime at least once a year and the importance of determining the quality of the soil. Application of 1–2 tons agricultural lime per hectare in extensive shrimp ponds was observed to be significantly effective in improving the pH and hastening the decomposition of organic matter in soil. Considerable water outflows from intensive and semi-intensive shrimp ponds made the lime ineffective. It was observed that liming showed no significant change in soil pH due to this water outflows. Proper water and soil management plus lime can improve the pH of newly renovated or constructed ponds and peripheral canals. To eradicate pests and predators, lime with ammonium sulfate is effective as a substitute for synthetic pesticides. | en |
