      abstract = {This study aimed to provide a basis for the rational  improvement of the microstructure of the soil that had been  planted with crops for a long time. Conventional and  micro-morphological methods were used to study the effects  of planting grain and cotton crops on soil properties in  Gaotang County, Shandong Province. The results showed that  long-term cultivation of grain and cotton crops has a  significant impact on soil micro-structure. The top soil  (0-10 cm) of wheat-maize field has higher organic matter  content, uniform aggregate size, high separation, and  strong packing void connectivity, forming a type  micro-structure that is conducive to agricultural  production. The characteristics of soil matrix are mainly  inherited from soil parent materials, and the impact of  crop cultivation on soil matrix is very weak. The amount of  formations in the soil is less, and only Fe nodules, Mn  nodules and excrement are observed. },
