Determination of fertility rating (FR) in the 3-PG model for loblolly pine (Pinus taeda L.) plantations in the southeastern United States
Soil fertility is an important component of forest ecosystem, yet evaluating soil fertility remains one of the least understood aspects of forest science. Phytocentric and geocenctric approaches were used to assess soil fertility in loblolly pine plantations throughout their geographic range in the …

Kolefnisbinding og vöxtur mismunandi skógargerða í þremur skógum á Suðvesturlandi Heiðmörk, Nesjavöllum og Ölfusvatni
Eitt af mikilvægum hlutverkum skógræktar er að binda koldíoxíð (CO2) úr andrúmslofti og geyma sem kolefni (C) í lífmassa og jarðvegi til lengri tíma. Aukin umræða og kröfur um notkun ábyrgra aðferða til þess að meta kolefnisbindingu skóga var aðal kveikjan að þessari rannsókn. Markmið þessa …
