Arbuscular mycorrhizal fungi colonization facilitates nitrogen uptake in cotton under nitrogen-reduction condition

mycolabadmin

This study shows that beneficial soil fungi (arbuscular mycorrhizal fungi) can help cotton plants absorb more nitrogen from soil, especially when nitrogen fertilizer is reduced. The fungi form partnerships with cotton roots and extend into the soil with thread-like structures that absorb nitrogen and transport it to the plant. The research demonstrates that reducing nitrogen fertilizer while using these beneficial fungi could improve crop growth while reducing environmental pollution from fertilizer runoff.

Analysis of the Differences in Rhizosphere Microbial Communities and Pathogen Adaptability in Chili Root Rot Disease Between Continuous Cropping and Rotation Cropping Systems

mycolabadmin

This study shows that rotating chili crops with cotton significantly improves soil health and reduces chili root rot disease compared to continuous chili cultivation. By changing crops, beneficial bacteria like Bacillus increase while disease-causing fungi like Fusarium decrease in the soil. The research identifies the main pathogens causing chili root rot and their growth preferences, providing farmers with a scientific basis for using crop rotation as a natural, sustainable alternative to chemical pesticides.

Impact of Oxalic Acid Consumption and pH on the In Vitro Biological Control of Oxalogenic Phytopathogen Sclerotinia sclerotiorum

mycolabadmin

Scientists studied how bacteria that eat oxalic acid can control a destructive plant fungus called Sclerotinia sclerotiorum. The fungus produces oxalic acid to damage crops, but when special bacteria consume this acid, they change the soil pH to become more alkaline, which the fungus cannot tolerate. This research shows that pH changes are just as important as removing the acid itself for controlling this pathogenic fungus in agriculture.
