How do microorganisms affect plant growth?

Through work originally designed to remove contaminants from soil, scientists have identified plant-associated microbes that can improve plant growth on marginal soil. The findings may help scientists design strategies for sustainable biofuel production that do not use food crops or agricultural land. read more

Just like plants, most micro-organisms prefer an acidity level of between pH 5.5 and 5.8. high and low pH levels, as well as pH fluctuations can disturb the development of micro-flora. still, some micro-organisms are able to grow or even flourish in extreme conditions. read more

Microorganisms in soil and their effect on Plant Growth: Merrick Hoffman May 7, 2013 Experiment: Steps Experiment: Growth Cycle Yes, the pictures confirm my hypothesis. I thought the plants would grow better in the soil with the microorganisms. The bacteria in the non-baked soil gave the plant enough nutrients, not only to live, but to thrive. read more
