In addition to nutritional factors, the productivity of many acid soils is affected by physical factors that include low water holding capacity （Oxisols, Spodosols） and susceptibility to crusting, erosion and especially compaction （Oxisols, Ultisols）.

除了养分因素外，许多酸性土壤的生产力受物理因素的影响，包括持水量低（氧化土，灰化土）和对结壳、侵蚀及特别是压实（氧化土、老成土）敏感。
