Concept:Culturable wasteland is land that is not currently cultivated but can be brought under cultivation after being left fallow for more than five years.
Explanation:Step 1: Culturable wasteland refers to potentially arable land that has remained uncultivated for a long period.
Step 2: The specific condition is that such land must have been left fallow for more than five years.
Step 3: This distinguishes it from other fallow categories: land fallow in the last four years (too short), land fallow between one and two years (current fallow), and land fallow for less than one year (short-term rotation).
Step 4: Reclaiming culturable wasteland requires interventions like soil improvement, irrigation, and sustainable farming practices to restore productivity.
Step 5: Identifying and rehabilitating this land helps increase agricultural output and supports food security goals.
Answer:Land that has been left fallow for more than five years.
