A paper or aluminum foil is placed over the samples during the drying process. Dried samples (between 15 and 20 plants, corresponding to between 5 and 10 mg as dry weight) are placed into PFA cups with ceramic tweezers and weighed. The PFA cups are placed in PTFE vessels, and nitric acid (1 ml) is added to the PTFE vessels outside the PFA cups.

Molybdenum is adsorbed strongly by oxides of aluminum and iron, thereby making the molybdenum unavailable to plants. Increasing aluminum in the soil solution also restricts the uptake of calcium and magnesium by plants. Aluminum ions are toxic to the roots of many plants such as cotton, tomato, alfalfa, celery, barley, corn, sorghum, and sugar beets.

Potassium is an essential element in plant growth and has an important role in regulating cell water potential and turgor in osmotic regulation. Potassium content in plants is high compared to trace elements, however, it is difficult to measure a relatively small change of potassium content in the large total. Here, we describe a procedure for measuring potassium in Arabidopsis that is easy to ...
