That's a lot of phosphorus. Someday people won't believe we just dumped untreated manure into the environment, in the same way we now cringe at the thought of doing the same with human waste.

US EPA has canceled grants related to PFAS transport through soils. Biosolids and composts can be contaminated with PFAS, so understanding how these compounds move after being applied to soils is critical to the responsible recycling of nutrients.

In our latest blog post, Chad Penn explores how excessive phosphorus uptake can actually reduce corn yields by disrupting the plant's nutrient balance. Using a soil-free system, this study examines how P interacts with other nutrients in the plant. Read our blog:
