Some essential nutrient elements in forest plants as related to species, plant part, season and location

Abstract

Natural vegetation common to the forested areas of Nova Scotia was sampied and analyzed for the nutrient elements calcium, phosphorus, cobalt, molybdenum, manganese, zinc and copper. Results showed considerable variation within and between species. Variations due to plant part, season and location of sampling also occurred but to a lesser degree. With the possible exception of molybdenum and copper, the elements are present in adequate quantities for normal nutrition. The average range of nutrient content for cobalt was found to be 0.09 to 0.44; molybdenum 0.01 to 0.32; zinc 13.0 to 91.0; manganese 44 to 594; copper 4.9 to 31.7 in terms of parts per million while calcium ranged from 0.36 to 1.11 per cent and phosphorus from 0.06 to 0.21 per cent.

Determination of metals in medicinal plants highly consumed in Brazil

“…Plants have the ability to accumulate metals essential TO their growth and developED from the soil and water -such as, Mg, Fe, Ms, Zn, Cu, Mo and Ni (Langille, MacLean, 1976). Some plants even have the ability to accumulate metals that have no known biological function to them, as Hg, Cr and others.…”

Fourth year response of aspen seedlings to lime, nitrogen and phosphorus applied at planting and 1 year after planting

“…The P concentrations declined over the 4 years and the treatment differences became smaller as growth utilized the additional nutrient from fertilizer application. The leaf P concentrations of about 1.6 g kg À1 reached at Drayton Valley may be near the lower limit at which aspen can function and has been observed previously in the field (Langille and McLean, 1976). Leaf deficiency symptoms also developed below a P concentration of 1.6 g kg À1 in a Populus trichcarpa  P. deltoides hybrid (van den Driessche, 2000).…”

Nutrient relations in coppiced black cottonwood and red alder

“…In general, however, our data for both species are within the ranges of concentrations reported for twigs of other hardwoods, including some Alnus and Populus spp. (Blackman et al 1979;Grigal et al 1979;Kubota et al 1970;Langille and Maclean 1976).…”
