Step 1: Understanding the Question:
The question tests the definition of biodrainage and culturable land.
Detailed Explanation:
• Statement I analysis: Biodrainage is the use of high-transpiring trees (like Eucalyptus) to remove excess groundwater and lower the water table in waterlogged areas. One of its primary advantages is that once established, it requires very low maintenance compared to mechanical drainage systems (pumps and pipes). Therefore, Statement I is incorrect.
• Statement II analysis: As discussed in previous questions, culturable land is defined by its potential capability for farming. Land that is already producing green biomass consistently is simply cultivated land or productive forest. The term "culturable" is usually applied to land that is currently not being farmed but could be. Therefore, the definition in Statement II is technically incorrect.
Step 2: Final Answer:
Both Statement I and Statement II are incorrect.
