卡罗拉多州南部圣·路易斯山谷的实验资料，证明了硝酸根离子淋溶及其经济分析软件能够分析不同作物品种的氮利用情况。这种软件的１．２版本，改进了一系列的地方参数，能够模拟出相同深度土层的不同作物、不同品种、不同的管理模式、不同的土壤类型的氮活动情况。这种对地方参数的改进以及模拟精度的提高能够直接反映出最好的管理模式对残留在土壤中的 ＮＯ３－－ Ｎ含量、细质地土壤剖面中的 ＮＯ３－－ Ｎ含量以及低秆谷物与蔬菜轮作制度的影响。新版本的模拟显示出：ＮＯ３－－Ｎ的有效淋溶过程可以反映土壤的质地状况，而且管理模式的好坏与 ＮＯ３－－ Ｎ淋溶程度有着内在的联系。这就是有利于保护与改善水质的重要的硝酸根离子淋溶及其经济分析软件。
Experimental data from the St. Louis Valley in southern Carolina demonstrate that nitrate nitrate leaching and its economic analysis software enable the analysis of nitrogen use in different crop varieties. Version 1.2 of this software, which improves a series of local parameters, can simulate nitrogen activity in different crops, different breeds, different management models, and different soil types for the same depth of soil layer. This improvement of local parameters and the improvement of simulation accuracy can directly reflect the best management model of NO3-N content in soil, NO3-N content in fine soil profile and the content of low-stalk grain and vegetable The impact of the rotation system. The new version of the simulation shows that the effective leaching process of NO3 - N can reflect the texture of the soil, and that the management mode is intrinsically linked to the degree of NO3 - N leaching. This is an important nitrate leaching and economic analysis software that helps protect and improve water quality.
