The determination of the number of bacteria, actinomycetes, and fungi in 72 soil samples of different sugar cane soils in North Bihar (India) and the calculation of the correlations between these values and the content of organic carbon, total nitrogen, total soluble salts, available P2O5, and water-soluble K2O gave these results: 1. Significant and positive correlations were found between the content of organic carbon in the soil and the number of actinomycetes and fungi. 2. Significant and negative correlations were found between the content of water-soluble salts and the number of microorganisms. 3. There is a significant and positive correlatin between the number of bacteria and fungi and the total nitrogen content and and the available P2O5.
对印度北比哈尔不同甘蔗土壤的72个土壤样本中的细菌、放线菌和真菌数量进行测定，并计算这些数值与有机碳、总氮、总可溶性盐、有效五氧化二磷和水溶性氧化钾含量之间的相关性，得出以下结果：1. 土壤中有机碳含量与放线菌和真菌数量之间存在显著正相关。2. 水溶性盐含量与微生物数量之间存在显著负相关。3. 细菌和真菌数量与总氮含量以及有效五氧化二磷之间存在显著正相关。
