Trends in Microbiology

Soil microbes play an essential role in the environment by contributing to the release of key nutrients from primary minerals that are required not only for their own nutrition but also for that of plants Although the role of fungi in mineral weathering is beginning to be elucidated the relative impact of bacteria in this process and the molecular mechanisms involved remain poorly understood

Differences in Distribution of Potassium

Potassium (K) has been recognized as an essential element in intensive agricultural production systems and deficiency of K usually results in a decrease in crop yields The utilization of potassium-solubilizing bacteria (KSB) to increase the soluble K content in soil has been regarded as a desirable pathway to increase plant yields Following the inoculation of KSB in the soil potassium can
