Why is testing for soil microbes important?

 Soil microbes like bacteria, fungi and actinomycetes are important for many reasons. They help move nutrients to and from the soil. They help with plant growth. They even help make substances that hold soil particles in aggregates, which helps the stability of soil. These microbes are small but exist in large numbers in soil. Soil … Continue reading Why is testing for soil microbes important?

How do soil microbes affect soil health and nutrient availability?

Soil is essential to life. That’s why we hear more every day about the microbes that inhabit soil1. What many don’t realize, however, is that those microbes are related to the emerging field of “soil health.” Microbes also affect how soils are tested in laboratories. This topic has captured the attention of farmers, scientists and … Continue reading How do soil microbes affect soil health and nutrient availability?
