pNa Ion TestersSimple tester determines sodium ion activity. Reasons for testing for sodium include: - Long term irrigation of farm land builds up an abundance of sodium which reduces crop yields
- With high sodium levels in soil, extra precautions must be taken to avoid over-compaction
- With high conductivity readings, pNa reading helps determine what portion is attributable to sodium
Pike Agri-Lab Supplies has two pNa testers available. The first is a pocket pNa tester which reads in pNa units and can be converted to ppm, using chart provided. The second is a multirange digital tester which reads directly in ppm and has a replaceable electrode.
