Poplar Leaf Tissue Chemical Analyses

Chemical analyses of poplar (treatment 8) leaf tissue in the fertilized main section of the field and unfertilized microplots. As of August 2013, the main section has been fertilized only once which was in June 2010 using Ammonium nitrate (156 kg N/ha or 140 lbs N/acre). The main goal of study is to determine nutrient efficiency of trees growing under two different regimes; fertilized versus unfertilized.
Chemical analyses include: carbon, nitrogen, aluminum, copper, iron, manganese, zinc, boron, sodium, calcium, magnesium, potassium, phosphorus, sulfur. All analyses are carried out by the Michigan State University Soil and Plant Nutrient Laboratory except carbon and nitrogen percent which are analyzed by the KBS LTER lab.

This datatable is part of the GLBRC Plant Chemical Analyses dataset.
