Example Sentences

"Then, we evaluated the composition of the soil-pathogen microbiome. What we found is that the variation in pathogen composition in monocultures significantly predicted the yield when combined. When there are distinct pathogen communities, mixing them leads to a greater release of pathogens from your neighbors. The worst scenario is when a neighboring crop has the same pathogens. In that case, you're experiencing double density -- your crop pathogens and those from your neighbor crop."
