Phosphorus is crucial for crop growth. But too little can lower crop yields, and too much can lead to pollution downstream. Studies show that some soils are losing phosphorus, while others are accumulating and leaking into waterways, says watershed researcher Monireh Faramarzi. "This creates confusion about what is actually happening in farm landscapes," she says, especially in areas with frequent freeze/thaw cycles.
