This is my own innovation: The history of Limpo grass

Livestock keeping is important in the Huetar Atlantica region among large medium- and small-scale farmers. It began 40 years ago with the felling of primary forest. Pasture soils are generally shallow with low fertility and farmers have suffered several setbacks in recent years. One of these was the introduction of Ratana (Ischaemum indicum). This improved variety is now the main grass in the region but it has turned out to be unproductive and low in quality.  So, Limpo grass was grown on a hectare of flood prone land where Ratana had been grown and which was nearly always covered with weeds. The grass grows aggressively and the cows produce more milk  and the calves grew fatter.
