Maina, J.N., 2011. Other studies have shown that the effects of precipitation, ground water and soil crust on the growth of H. ammodendron are mainly realized by affecting soil water content (Quanlin et al., 2007). This is because H. ammodendron dies when water content in Aeolian sandy soil is less than 0.824%, degenerates when water content is between 0.824% and 1.30%, and grows normally when water content is above 1.30%. A study to monitor growth of H. ammodendron in relation to soil water content is being carried out and results will be out soon.
