What do we know about heavy metals in soil? What do we know about lead exposure through soil and garden plants? What do we know about cadmium and arsenic in soils? What can I do if I’m at risk for heavy metals in my garden soil?
Phosphorus is an important plant nutrient for growing dairy forages. Unfortunately, many dairies have more phosphorus excreted and stored in manure than they can use during a crop year. Soils have the ability to store moderate over-applications of phosphorus for future crop production, but continued over-application can lead to losses of phosphorus to surface water.
Forage quality of common pasture weeds was determined through laboratory testing to compare feed value of weeds to desirable forage species and nutrient requirements for grazing livestock.
