An appraisal of nutrient supplies available for tree growth in a pumice soil [PDF]

open access: yes, 1970
Chemical analyses have confirmed and explained the results of an earlier pot trial in which the availability of major nutrients in six pumice ash layers of Kaingaroa silty sand was assessed by the growth of radiata pine seedlings. Almost all of the tree-

The Mineral Requirements Of Radiata Pine Seedlings [PDF]

open access: yesNew Zealand Journal of Agricultural Research, 1961
Summary 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
