Phosphorus is essential for crop production, but too much of it in the wrong place creates problems. Across South Dakota and the Northern Great Plains, phosphorus buildup from manure applications is becoming a growing concern for soil health, water quality, and long-term nutrient management flexibility.
This fact sheet explains how feeding strategies, especially the use of low-phytate corn and related diet adjustments, can reduce phosphorus excretion in swine manure. These changes improve the nitrogen to phosphorus balance of manure and help producers better align manure nutrients with crop demand.
