WebCalcium in the soil tends to improve aeration, while Mg favors the adhesion of soil particles. Thus, if the Ca/Mg ratio is very low, which means that much of the exchange complex will be occupied by these Mg ions, the soil becomes less permeable, harming the development of the crops. Because of this, the Ca/Mg ratio should always be kept above 1. http://niayeshstone.com/water-absorption-rate/
