Total manganese, copper, zinc, organic and exchangeable iron, manganese, copper and zinc related significantly to organic matter, readily oxidizable carbon, humic acid, fulvic acid.

有机质对土壤有机磷及其组分的影响远远大于无机磷及其各组分，除全铁外、全锰、铜和锌及有机态铁、锰、铜和锌和交换态铁、锰、铜和锌均与有机质总量、易氧化碳、HA和FA等之间呈显著或极显著正相关。

The contents of organic matter, total nitrogen, phosphorus, iron, manganese, copper, zinc can be increased, and the contents of hydrolizable nitrogen and their forms , Fe-P, Al-P, Ca〓-P, all organic P forms, exchangeable and organic iron, manganese, copper, zinc are increased obviously in long-term application organic manure soil. Not only the contents of soil readily oxidizable carbon, humic acid, fuluic acid, and HA/FA value are increased and Kos value decreased but also the available nitrogen, phosphorus, iron, manganese, copper, zinc are kept more high level in the organic manure soils. Long-term mulching straw has similar role with organic manure for soil nutrient except for decreasing total phosphorus, available P, N and Ca〓-P, but its fertilizer efficiency is not better than organic manure.

有机肥还具有提高土壤易氧化碳和松结态腐殖质含量，降低kos值，提高土壤HA、FA含量及其比值的作用，使土壤中有效态氮、磷、铁、锰、铜和锌含量处于中上等水平；长期秸秆还田除了不增加土壤全磷、有效氮和磷等外，对其他养分的作用效果与有机肥相似，但其肥效不如有机肥；长期氮磷化肥单施，土壤全氮和磷增加，有机质、铁、锰、铜和锌含量下降，易氧化碳、松结态腐殖质、HA和FA含量、kos和HA/FA值下降；长期不施肥土壤有机质、全氮等养分处于消耗状态。
