Answer: Option B
Solution
Answer: Option B
Solution:
Acis sulphate soil is the soil or sediments containing iron sulphides. Iron sulphides are micro-crystalline minerals such as pyrite that have formed naturally in soils where long-term water-logged conditions occur. When it is disturbed by drainage, lowering of water tables, or excavation, oxidation of the sulphides creates sulphuric acid which can trigger a range of flow-on effects.Thus, the useful practice to manage acid sulphate soil is keeping the soil waterlogged.
