Abstract

Manure, collected from cattle housed in yards, was spread on experimental plots at the rate of 120 tonnes per hectare per annum. The manure was applied to 2 plots at 6-monthly intervals while a further 2 plots received monthly applications. Samples of manure soil, run-off and ground waters were examined for their counts of total aerobic bacteria, coliforms, faecal coliforms and for the presence of salmonellae. Comparison of the bacterial counts from samples from the test plots to those of the control plots showed that no change occurred in the levels of coliforms or faecal coliforms over the 3 years of manure application. One hundred and fifty-seven isolations of salmonella were made from the soil and water samples, but only 51 could be attributed to the manure. No difference was observed in the effects of different application frequencies.

摘要

从圈养牛场收集的粪便，以每年每公顷120吨的速率施用于试验田。粪便每隔6个月施用于2块试验田，另外2块试验田则每月施用。对粪便、土壤、径流和地下水样本进行了需氧细菌总数、大肠菌群、粪大肠菌群计数以及沙门氏菌检测。将试验田样本的细菌计数与对照田样本的细菌计数进行比较，结果表明，在施用粪便的3年中，大肠菌群或粪大肠菌群水平没有变化。从土壤和水样中分离出157株沙门氏菌，但只有51株可归因于粪便。不同施用频率的效果没有差异。
