Soil bacteria are important for soil health and plant growth in farms. Scientists in Hungary studied how different farming methods affect soil bacteria. They looked at soil samples from all over the country and found that the type of farming method used changes the types of bacteria in the soil. They also found that the chemicals in the soil affect the bacteria. This means that the way farmers manage their soil can change the types of bacteria living in it. This is important to consider when trying to keep soil healthy on farms.
