Cerrado is fairly unique for the flat Savanna terrain, the need for soil ammendments, mechanical harvesting, and this, irrigation. 20% of Dattera is irrigated, and the range at most farms is in that range. I don't know of a farm that is 100% irrigated but it might exist. Circular overhead (pivot) irrgiation like this is common, but drip/emitter irrigation is being introduced, the problem being that the cost of hosing is very high. Even Daterra is daunted by the costs of drip irrigation. Also, coffee has a very deep and wide root pattern so hose irrigation needs to account for this.
