With potential acidity increasing, totalorganicphosphorus, moderately resistant organic phosphorus, and highly resistant organic phosphorus in larch plantations decreased for all stands.
随着土壤潜性酸度的增加,各年龄阶段森林土壤有机磷总量、中稳性有机磷和高稳性有机磷含量降低。

The results showed that straw application increased crop yield, soil organic carbon accumulation, soil total nitrogen and phosphorus content as well as phosphorus activation.
结果表明,秸秆还田提高了作物产量,增加了土壤有机碳积累和土壤氮磷含量,且能活化土壤磷素。

Contribution rate of the organic matter and kalium upon latent soil benefit was the biggest, and totalphosphorus 'was the least.
