minerals through their stomata, and in some cases through their cuticles. This research is consistently cited in the argument that foliar feeding is 8, 10, or even 20 times more effective than traditional soil application. In assessing the advertised claims for foliar feeding of shrubs and trees, I had particular questions that areFile Size: 28KB. Most of Washington's natural stand Douglas-fir Christmas trees are grown on gravelly, droughty, and infertile soils-such as the Everett and similar soil series-in Kitsap, Pierce, and Mason counties. Christmas trees which are grown on these dry, gravelly soils grow slowly.
--Foliar fertilizer applications to ponderosa pine and Douglas-fir seedlings during bud initiation treatments significantly impacted seedling quality. Timing of bud formation was undisturbed in ponderosa pine seedlings but delayed in Douglas-fir seedlings by foliar fertilization.

I use this mixture a few times a month. Just to make the trees healthier and make sure they have everything that they need. The mineral nutrition of forest tree seedlings is conditioned by a number of factors seldom considered to be very critical with agricultural and horticultural crops. For example, (1) planting often is done on rather adverse sites where mineral nutrients, organic matter, soil mois.

Needles of nursery-grown seedlings were in the same size range as those of for- est-grown seedlings, except for those in the Trout Creek division at Wind River (table 1).
Needles of seedlings in the Trout Creek division were considerably shorter. Trends in nitrogen, phosphorus, potassium and calcium content of the leaves of some forest trees during the growing season.

The ability of endophytes to colonize the interior of plants could confer benefits to host plants that may play an important role in plant adaptation to environmental changes.
