 Among other benefits of these trees is that they have root-systems that penetrate much deeper and do not compete with shallow-rooted plants, like grass (once the trees have attained a certain maturity).This means that the land can be used for multiple purposes, such as grazing for animals.Yet another benefit of using Millettia Pinnata to produce bio-diesel is that it can tolerate low rainfall (as little as 250 ml per year), far below what most food-crops require, thus reducing yet more their potential to compete.
