I use manure from goats to grow avocado, my trees are so healthy. During 2016, I sold avocados and got TZS. 210,000 from only 3 trees. In the past, I could only harvest a few avocados which were not enough for sale. I used the income to buy a Television set and installed solar panel. Since I installed solar panel, my children can study a couple of more hours during the night than it was before with traditional kerosene oil lamp ‘kibatari’.
