对纽约西部的一些泥炭土地区进行了一项研究，发现这些地区对蔬菜作物没有生产力。初步研究表明，这些土壤含有大量的锌。后来，定量测定证实了这些观察结果。温室研究强烈表明，过量的锌是负责在该领域观察到的非生产性条件。菠菜植物生长在一个生产泥炭油已添加尽可能多的锌是自然存在于贫瘠的土壤有同样的有毒症状的植物生长在贫瘠的土壤。将莴苣和胡萝卜分别用作指示作物时，观察结果基本相同。化学研究表明，土壤中的锌主要以可交换的形式存在，而不是以水溶性形式存在。进行了详细的实地调查，以确定锌在受影响地区表层土壤中的分布。锌的含量范围为0 - 6.7%，以土壤干重计。参考文献18篇，表格6个。
A study was made of some peat soil areas of western New York which were found to be unproductive for vegetable crops. Preliminary work indicated that these soils contained large amounts of zinc. Later, quantitative determinations were made which confirmed these observations. Greenhouse studies strongly indicated that an excess of zinc was responsible for the unproductive conditions observed in the field. Spinach plants growing on a productive peat oil to which had been added as much zinc as was naturally present in a poor soil had the same toxic symptoms as the plants growing on the poor soil. Essentially the same observations were noted when lettuce and carrots, respectively, were used as indicator crops. Chemical studies showed that the zinc was held in the soils largely in an exchangeable and not a water-soluble form. A detailed field survey was made in order to determine the distribution of zinc in the surface soils of the affected areas. The amounts of zinc found ranged from 0 to 6.7% on the basis of the dry weight of the soil. 18 references, 6 tables.
