Abstract

Incubation of single bulk sample of freshly collected red sandy soil in trays showed immediate response to added nutrients both in dehydrogenase activity and bacterial and fungal populations. The prevailing acidic pH might have been responsible for the observed response of fungi as well. Actinomycetes population did not fluctuate. It was therefore suggested that TTC dehydrogenase technique for measuring the biological activity could be applicable to coarse-textured and more open soils. There were indications that fungi contributed to the soil dehydrogenase activity as well.

摘要

将新鲜采集的红色沙土的单个大量样本置于托盘中培养，结果表明，添加养分后，脱氢酶活性以及细菌和真菌数量立即出现反应。土壤普遍呈酸性的pH值可能也是观察到的真菌反应的原因。放线菌数量没有波动。因此有人提出，用于测量生物活性的TTC脱氢酶技术可能适用于质地粗糙、孔隙较多的土壤。有迹象表明，真菌也对土壤脱氢酶活性有贡献。
