According to the principles discussed, what is required for a subject engaging in commercial mechanized farming on stool land?

The question seems to be missing some context, but based on general principles, the following steps might be required for a subject engaging in commercial mechanized farming on stool land:

1. Permission from the Stool/Skin: Stool lands are lands owned by the traditional authorities or chiefs, so the first step would be to seek permission from the relevant authority.

2. Land Lease Agreement: After getting permission, a land lease agreement would need to be drawn up. This agreement should specify the terms and conditions of the lease, including the duration and the lease rate.

3. Land Preparation: Once the lease agreement is in place, the land would need to be prepared for farming. This could involve clearing the land, ploughing, and harrowing.

4. Acquisition of Farming Equipment: Mechanized farming requires the use of machinery. The subject would need to acquire the necessary equipment such as tractors, ploughs, and harvesters.

5. Planting: After the land has been prepared and the necessary equipment acquired, the next step would be to plant the crops.

6. Maintenance: This involves watering, weeding, and protecting the crops from pests and diseases until they are ready for harvest.

7. Harvesting: Once the crops are mature, they would need to be harvested using the appropriate machinery.

8. Marketing and Sales: After harvesting, the produce would need to be marketed and sold.

9. Payment of Lease: The lease rate agreed upon in the lease agreement would need to be paid to the stool/skin.

10. Reporting: Depending on the terms of the lease agreement, the subject may be required to provide regular reports on the farming activities to the stool/skin.

Please note that these steps may vary depending on the specific context and local regulations.
