Suometsän lannoitus eloperäisillä lannoitteilla

Valmari A. Suometsän lannoitus eloperäisillä lannoitteilla.

Tiivistelmä

The main content of this paper has been published in English by Valmari (1974). The use of organic waste materials for manuring forest seems to offer, at least in the conditions prevailing in Northern Finland, a method which both from an economic and from an ecologic view point is acceptable and available in cases where ploughing into the soil of tilled fields is for some reason an inferior method.
