The harms of soil compaction represented briefly as soil bulk density and penetration resistance increased, macroporosity decreased, soil physical, chemical and biological properties deteriorated, which effected on crop growing and soil structure degradation, and has become one of the principal obstacle factors for sustainable development of agriculture
土壤機械壓實危害主要表現在土壤容積質量和機械阻力增加，大孔隙減少，土壤物理、化學、生物性狀惡化，進而影響作物的生長發育，土壤結構發生退化，已成為當前制約農業可持續發展的障礙因素之一。 -
The soil owns better density degree. higher shearing resistance and low compaction, but it ' s crude water content is low, cohesive gravel content is small
