Plant growth and primary production in tundra areas can be limited by the availability of inorganic nutrients as shown by Warren-Wilson (1957), Schultz (1964), and others. More recently, attention has focused on the experimental response of tundra plants to enrichment by N (Haag, 1974) and/or P (Chapin, 1978; Chapin et al., 1975; McKendrick et al., 1978). Rigorous attempts to determine nutrient deficiencies in situ, however, have not been undertaken in tundras.
