available fertile farmland

I have a 5 acre farm that was inherited. It's in Nyeri. Currently, it has 500 trees of coffee, and the rest has been rented out. However, I find renting out to be counterproductive since the soils get depleted whereas the payments are very meagre.
My challenge is I have zero farming experience, ata ile ya agriculture high school...haha! I'm looking for a strategic partner to put the land into p[productive use, someone with good farming and market produce knowledge.
