Abstract This work investigates the usefulness of glauconite as an alternate fertilizer by field experiments on growing durum wheat. Separate field experiments using glauconitolite and original soil compare the effectiveness of different products for agronomic applications. The addition of glauconitolite to soil increases the grain yield of wheat significantly. Glauconite undergoes noticeable structural and chemical changes in the soil during the growing season of wheat. The addition of glauconite improves the soil physico-chemical properties by enhancing concentrations of organic carbon, nitrates, exchangeable ammonium, K, P, Ca and Mg. The pH of the originally acidic soil increases from 6.0 to 6.7 with the application of glauconitic products. The increased K, P, Ca and Mg contents in the soil are associated with the complex chemical composition and ion-exchange capacity of glauconite. The K2O content of the original glauconite decreases by about 24% during one growing season. This study, therefore, demonstrates glauconitic rocks as environment-friendly, and slow release fertilizers.

添加海绿石肥对植物生长的研究

摘要 这项工作通过种植硬粒小麦的田间试验研究了海绿石作为替代肥料的有用性。使用海绿石和原始土壤的单独田间试验比较了不同产品在农艺应用中的有效性。向土壤中添加海绿石可显着提高小麦的籽粒产量。在小麦的生长季节，海绿石在土壤中会发生显着的结构和化学变化。添加海绿石通过提高有机碳、硝酸盐、可交换铵、钾、磷、钙和镁的浓度来改善土壤理化性质。随着青光石产品的应用，原本酸性土壤的pH值从6.0增加到6.7。增加的 K, P, 土壤中钙和镁的含量与海绿石复杂的化学成分和离子交换能力有关。在一个生长季节，原始海绿石的 K2O 含量下降约 24%。因此，这项研究表明，青海岩是一种环境友好型缓释肥料。
