Reducing N and P rates also decreased N and P accumulation and nitrate content in the soil and decreased the risk of N and P running off.

减少氮磷化肥用量可以大幅度降低氮磷在土壤中的累积和硝酸盐的含量，减少氮磷的流失风险。

P fertilization increased N, P and K accumulation in tree biomass and nutrient use efficiency in wood and biomass production.

施P肥还增加了树木N、P和K的养分积累量，提高了上述养分的利用效率。

The threshold and accumulation effects of N deposition could also be predicted by an intermediate disturbance hypothesis(IDH).

沉降的阈值效应和累积效应也都符合中度干扰理论。

Some recent studies have revealed a significant concentration of particles in near-surface waters in areas of mid-ocean accumulation (N Pacific and NW Atlantic gyres).
