The Plant Protection Laboratory (PPL) can test for soil fertility. The test provides information on pH and soluble salts. Both pH and soluble salts (salinity) are important in determining whether or not plants will grow. Soils with low soluble salts are generally safe for all plants and seedlings whereas very few plants will tolerate soils which are very saline.
