Response of Typical Shrubs Growth and Soil Nutrients to Graphene Addition in Impoverished Land of the Ulan Buh Desert.

As shown in Figure 2 , graphene addition resulted in a highly significant positive correlation between shrub height and basal diameter ( p < 0.01), and a significant negative correlation with available soil phosphorus ( p < 0.05).
