In order to study the effects of novel porous amendments on improving aeration of clayey yellow soil, an experiment was conducted in Bijie of Guizhou by adding different proportions of amendments to soil, and then soil porosity and aeration porosity were measured. The results showed that soil porosity and aeration porosity were increased with the increase of the proportion of novel porous amendments. Compared with CK, soil total porosities under 7.5%, 15.0% and 22.5% amendment-adding treatments increased by 2.7%, 3.1% and 3.2%, respectively, and soil aeration porosities increased by 2.7%, 8.6% and 10.6%, respectively. After the water saturation, 130 h, 52 h, 34 h and 37 h were required to provide oxygen enough to ensure the growth of the crops for CK and three amendment-adding treatments, respectively. It shows that the novel porous amendments can effectively increase soil porosity and improve soil aeration of clayey yellow soil, thus, is a new way to improve clayey soil.
