Movement of bacteria in the soil and the rhizosphere

mycolabadmin

Bacteria in soil move in many different ways to find food and avoid danger. Some swim using tiny whip-like flagella, others slide across surfaces, and many hitch rides on fungi or get transported by tiny predatory organisms. The ways bacteria move depend heavily on soil moisture, pore structure, and interactions with other microorganisms. This movement affects nutrient cycling and soil productivity, making it important for agriculture and ecosystem health.

Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

mycolabadmin

This study examined how a beneficial fungus called arbuscular mycorrhiza affects bacteria that break down ammonia in soil. Researchers tested 50 different agricultural soils and found that the fungus suppressed ammonia-oxidizing bacteria populations. Interestingly, the presence of the fungus actually increased ammonia levels in soil while decreasing nitrate, suggesting the relationship is more complex than simple competition for nutrients.

Organic and Inorganic Amendments Shape Bacterial Indicator Communities That Can, In Turn, Promote Rice Yield

Farmers wanting to grow more rice while protecting the environment can benefit from combining chemical fertilizers with mushroom waste. This combination encourages specific beneficial bacteria in the soil that help break down organic matter and make nutrients available to rice plants. The study found that soil health measured through microbial activity is a better predictor of rice harvest than traditional soil chemistry tests, suggesting that managing soil microbes should be a priority for sustainable farming.

Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

This study examined how a common soil fungus called arbuscular mycorrhiza affects bacteria and archaea that process ammonia in agricultural soils. Using 50 different soils from the Czech Republic, researchers found that the fungus suppresses ammonia-oxidizing bacteria but not archaea. Interestingly, the fungus actually increased ammonia levels in soil rather than depleting them, suggesting the suppression works through mechanisms beyond simple competition for nutrients.

Review: roles of mycorrhizal symbioses and associated soil microbiomes in ecological restoration

This comprehensive review explains how underground fungal networks and soil microbes are essential for restoring damaged lands, particularly those contaminated by mining or pollution. The research shows that using native fungal communities from early successional stages, rather than introduced or late-stage species, significantly improves restoration success. Specific plant species like fescues work particularly well with these fungal partners, and combining different microbial species creates synergistic effects that boost plant growth and reduce contaminants in soil.

Ancient Microbiomes as Mirrored by DNA Extracted From Century-Old Herbarium Plants and Associated Soil

Scientists extracted and analyzed ancient DNA from plant roots and soil samples stored in herbarium collections for over 120 years. The DNA showed typical signs of age and preserved microbial communities that originally lived in the soil around these plants. By comparing these ancient microbial communities to modern ones, researchers found that herbarium storage preserved the original characteristics of soil microbiomes, making these museum specimens valuable for studying how farming practices have changed soil ecosystems over time.
