Do you have some pictures of the property?
Some soil test results? No offence, but the land could be useless for some vegetation, but good for other.
No offence taken because your concern about the qualities of the land is valid. I'll have photographs from the parcel posted. Though, the area generally shares
these soil characteristics. Since the area has one rainy season, I would do vegetable crops during the onset of the rainy season, pulses mid season and finally end with lentils during the dry season. There is the option of integrating permaculture into the mix, with a mixture of fruit (Mango, Orange) and nut (Macadamia, Cashew) trees providing the backbone of the entire operation.
