Bacterial and fungal biomass was estimated in incubated samples of three cultivated soils, the influence of glucose, ammonium nitrate and cattle slurry on its formation being studied. The microbial biomass was determined in stained microscopic preparations of soil suspension. Bacterial biomass in the control samples was from 0.17 to 0.66 mg dry wt per 1 g dry soil and independently of the applied supplements was on the average two times larger in muck soils than in sand. Fungal biomass in the control soils ranged from 0.013 to 0.161 mg dry wt per 1 g dry soil, no relationship being found between its size and the soil type. As a result, the ratio of the size of fungal to bacterial biomass was dependent on the soil type; in sand the fungal biomass corresponded to 1/3 of the bacterial biomass, and in muck soils--only to 1/7.
对三种耕种土壤的培养样本中的细菌和真菌生物量进行了估算，并研究了葡萄糖、硝酸铵和牛粪浆对其形成的影响。微生物生物量通过土壤悬浮液的染色显微制剂来测定。对照样本中的细菌生物量为每1克干土0.17至0.66毫克干重，且与施用的添加物无关，平均而言，腐殖土中的细菌生物量比砂土中的大两倍。对照土壤中的真菌生物量为每1克干土0.013至0.161毫克干重，其大小与土壤类型之间未发现相关性。因此，真菌与细菌生物量的大小比例取决于土壤类型；在砂土中，真菌生物量相当于细菌生物量的1/3，而在腐殖土中仅为1/7。
