比较了14种土壤-作物系统氮素周转模型。 比较包括模型中所包括的过程、过程描述的方法以及使用相同数据集进行的模拟结果。 它的结论是，模拟的地上过程比地下过程的问题较少。 没有一个模型可以解释在春末夏初施肥后不久发生的矿质氮的损失。
Fourteen models of the nitrogen turnover in the soil-crop system were compared. The comparison comprised the processes included in the models, the methods of process description, as well as the results of simulations carried out with the same data set. It is concluded that simulation of the aboveground processes was less problematic than that of the belowground processes. None of the models could account for the loss of mineral nitrogen occuring shortly after application of fertilizer in late spring and early summer.
