On the seasonal changes of root system of a pine stands on the peatlands
The seasonal changes of the roots systems of a pine stand on the peatlands have been studied with samples collected during summers 1952-1954 and winter 1955. There are altogether seven sample areas that are located in the district of Korkeakoski.
The amount of roots is at the smallest in the spring, increasing then rapidly and peaking at the end of July. After that the amount of roots decreases again against the winter to the same size than in the spring. Variations seem to be similar in every year and also similar to other studies on mineral soils.

Mabadiliko ya msimu ya mfumo wa mizizi ya mti wa msonobari kwenye peatlands yamechunguzwa na sampuli zilizokusanywa wakati wa majira ya joto ya 1952-1954 na majira ya baridi ya 1955. Kuna jumla ya maeneo saba ya sampuli ambayo ziko katika wilaya ya Korkeakoski. Kiasi cha mizizi ni kidogo katika spring, kuongeza kisha haraka na kilele mwishoni mwa Julai. Baada ya hapo kiasi cha mizizi hupungua tena dhidi ya majira ya baridi hadi ukubwa sawa na katika spring. Tofauti zinaonekana kuwa sawa katika kila mwaka na pia sawa na masomo mengine juu ya udongo madini. PDF ina muhtasari katika Kifinlandi. Ilichapishwa mwaka 1955.
