Hello Sean!
A 6-hectare idle land is quite big and can be maximized by planting different crops suitable in your area.
You can start with cash crops, like vegetables in a small part of your land. Some vegetables are ready for harvest in less than a month.
May I also recommend to you our online courses that can be very useful. By enrolling, you will have an idea on what to plant in your land.
I hope you find our online courses interesting. Thank you and happy e-Learning!
