Researchers investigate 'whole farm' approach to reduce dairy pollution

"sequestered" in Central Texas soils. But some of the phosphorus in dairy manure is water-soluble, so what isn't sequestered is at risk of being washed off into streams and rivers by heavy rains.Once it reaches lakes and reservoirs, phosphorus itse...
