在诺曼·威尔斯，N.W.T.建立包括对照、对照加油、对照加油和肥料（磷酸脲，27：27：0）、对照加油和细菌以及对照加油、肥料和细菌的重复田间小区，加拿大在3年的时间内监测微生物数量和回收油的化学组成的变化。在施肥的地方，细菌数量迅速增加，但真菌繁殖体没有增加。其次是迅速消失的正构烷烃，类异戊二烯，和饱和化合物的回收油中的重量的连续损失。沥青质、芳烃、含氮、含硫和含氧馏分含量的变化也进行了讨论。用石油降解菌播种浸油地块对回收油的组成没有任何影响。施肥的地块表现出更快的速度植被与棉花草和拉布拉多茶是植被的优势物种。
Replicate field plots comprising a control; control plus oil; control plus oil and fertilizer (urea phosphate, 27:27:0); control plus oil and bacteria; and control plus oil, fertilizer, and bacteria were established at Norman Wells, N.W.T., Canada. Plots were monitored over a 3-year period for changes in microbial numbers and the chemical composition of recovered oil. Where fertilizer was applied, there was a rapid increase in bacterial numbers, but no increase in fungal propagules. This was followed by a rapid disappearance of n-alkanes, isoprenoids, and a continuous loss in weight of saturate compounds in recovered oil. Changes in the content of asphaltenes, aromatics, and nitrogen-, sulphur-, and oxygen-containing fractions also are discussed. The seeding of oil-soaked plots with oil-degrading bacteria did not have any effect on the composition of recovered oil. Fertilized plots showed a more rapid rate of vegetation with cotton grass and Labrador tea being the dominant species in revegetation.
