dc.description.abstract |
In this study, all inoculated pulse crops formed nodules that release H2 to the surrounding soil (HUP- nodule). The soil around HUP- nodules showed a higher H2 uptake rate and CO2 fixation. The barley inoculated with soil adjacent to HUP- pulse nodules tended to have higher shoot and root growth, particularly for the barley inoculated with soil around
the HUP- nodules of faba beans and dry beans. The HUP- nodules triggered alteration in the soil bacterial community. The greatest changes of bacterial community structure were also evidenced in the soil around the HUP- nodules of faba beans and dry beans. The
profound changes in the bacterial community structure could be the reasons for increased growth seen on barley plants inoculated with soil around the HUP- nodules of faba beans and dry beans at a lower nitrogen level. Therefore, pulse production could potentially
have positive effects on soil health and the growth of succeeding crops. |
