The lower parts of our farm (Central Tanzania, East Africa, ~70 acres, in development since 2017) are vertisols (~1m) with an expansive clay sublayer (don’t know how thick, but at least 2m). During the rainy season it can get flooded for a few hours (because of landscape degradation surrounding our farm) until surface waters run of.
Right now I’m trying to plant grasses (vetiver, rhodes grass, cenchrus) and fodder trees (leucaena, gliricidia, and faidherbia) to develop a grazing area.
Any trees that could grow and maybe even penetrate the clay layer? Any other thoughts for improving the area?
