Turpeentuhkan vaikutuksesta puuston kasvuun ja ravinnetilaan käytännön lannoitustyömailla
Silfverberg K., Issakainen J. Turpeentuhkan vaikutuksesta puuston kasvuun ja ravinnetilaan käytännön lannoitustyömailla.
English title: Growth and foliar nutrients in peat-ash fertilized standsTiivistelmä
This study included growth and needle analysis in ash-fertilized spruce and pine stands near Oulu (65 °N, 26 °E). Most of these stands, totalling 770 measured trees, were on peat and fertilized in wintertime 1980 and 1981 as practical work with 40 m3/ha. By 1985 there was a clear increment of growth, especially in spruce stands, probably due to the great amount of phosphorus (375 kg/ha) applied. Keywords: peatland forestry, tree growth, ash-fertilization, phosphorus.
