“…Foliar data from other sources indicate that Chamaecyparis often has considerably lower Ca levels than Thuja (Table 5), although both species have higher foliar Ca concentrations than most other conifers (Ovington 1956;Zobel and Liu 1979). Abundant soil Ca seems to be important to Thuja (Gessel et al 1951;Krajina 1970), and Thuja has been associated with relatively high soil Ca: Mg ratios elsewhere (Feller 1977). Its affiliation with abundant Ca may be related to its reported preference for soils in which nitrification is vigorous (Krajina 1970 Chamaecyparis coincides closely with the occurrence of Flournoy sediments as mapped by Baldwin (1974), and Hawk (1977), in his phytosociological study of Chamaecyparis, apparently found no significant occurrence on this geological formation.…”

Surface mineral soil and foliage associated with Chamaecyparislawsoniana (A. Murr.) Parl. and Thujaplicata Donn ex D. Don were sampled at six sites in southwestern Oregon. Total soil nitrogen concentrations ranged from 0.08 to 0.37%. Percentage exchangeable concentrations of other soil nutrients were 0.0002–0.0020 P, 0.014–0.224 Ca, 0.002–0.018 K, and 0.002–0.023 Mg. Foliage of Chamaecyparis contained 0.9–1.9% N, 0.11–0.23% P, 0.8–1.9% Ca, 0.67–1.20% K, and 0.11–0.26% Mg. Foliage of Thuja contained 0.9–1.6% N, 0.12–0.24% P, 1.1–2.0% Ca, 0.52–0.95% K, and 0.06–0.23% Mg. Overall, foliage of Chamaecyparis contained significantly higher concentrations of K, and tended to have lower Ca:Mg ratios than that of Thuja. Concentrations of soil nutrients showed no obvious relation to species occurrence on a study-wide basis. Within sites where the two species grew together, however, Thuja was associated with higher soil Ca:Mg ratios and foliar Ca, and Chamaecyparis was associated with higher levels of soil K and foliar N. Foliar nutrient concentrations showed little relation to concentrations in soil, although low soil Ca, P, and Mg concentrations were reflected in foliage at some sites. Soils in the study area have higher Ca:Mg ratios and more available N than soils over much of Chamaecyparis' range. Given the apparent nutritional requirements of Thuja, it seems unlikely that it will significantly replace Chamaecyparis killed by root rot.

“…Nevertheless, relatively high concentrations of calcium and low concentrations of nitrogen are nearly always present (see Gessel et al 1951, Tarrant et al 1951, Daubenmire 1953, Ovington 1956, Beaton et al 1965, Webber 1973. Phosphorus concentrations are usually low, but Smith et al (1968) found them to be higher in western redcedar than in Douglas-fir or western hemlock.…”

“…Studies designed to correlate growth with nutrient supply and foliage composition have been carried out on many other forest tree species, e.g., Pinus strobus (Mitchell 1939), Thuja plicata (Walker et 01. 1955), P. taeda and P. virginian a (Fowells and Krauss 1959), P. sylvestris (Ley ton and Armson 1955;Tamm 1956;Boszormenyi 1958), Larix leptolepis (Ley ton 1956(Ley ton , 1957van Goor 1953), Pseudotsuga taxifolia (Gessel et al 1951), Picea abies (Ingestad 1959), and Betula verrucosa (Ingestad 1957).…”

Radiata pine seedlings were grown in water cultures and perlite cultures in which N, P, K, and Mg were supplied at several rates. It was found that deficient or excess supplies of most nutrients cause chlorosis. The blue-green foliage on P-deficient seedlings is an exception. The patterns of chlorosis produced by N, K, and :M g deficiencies are distinct and characteristic. Quantities of 100 p.p.m. of N, 1 p.p.m. of P, 10 p.p.m. of K, am: 10 p.p.m. of Mg in the nutrient solution are sufficient to maintain good growth in seedlings. These levels are low when compared with those obtained in some other studies, but they are of the same order as the concentrations found in the soii solutions of two New Zealand soils known to support vigorous plantations of radiata pine. In an experiment of this nature it is important to have the basic nutrient concentrations similar to levels found in soil solutions, otherwise optimum levels of supply and critical foliage levels may not apply to plants grown under field conditions. Foliage contents of 1.6% of N, 0.10% of P, 1.1% of K, and 0.11% of Mg indicate adequate supplies of each nutrient. The excess or deficient supply of one nutrient causes characteristic changes in the uptake of other nutrients. INTRoDUCTIOK Although radiata pine (Pinus radiata D. Don) has only a very restricted natural range along the California coastline, it is proving to be an adaptable and very productive species in many countries, especially in the temperate zone of the southern hemisphere. Planted on widely differing sites, it has been found in some cases to suffer from mineral deficiencies. In Australia applications of phosphorus and zinc to the soil have corrected deficiencies of these elements (Kessell and
