Typpilannoituksen ja harventamisen kasvuvaikutukset kaksijaksoisessa mänty–kuusisekametsässä

Typpilannoituksen ja harventamisen kasvuvaikutukset kaksijaksoisessa mänty–kuusisekametsässä

Tutkimus tehtiin kangasmetsän kestokokeilla Muhoksella ja Jämsässä. Ylempää mäntyjaksoa harvennettiin metsänhoitosuositusten mukaisesti ja lannoituskäsittely 138 kg typpeä hehtaarille toistettiin kahdesti 15‒22 vuoden tutkimusjaksoilla. Alikasvoskuusikko harvennettiin tiheyteen 2000 kpl ha–1 tai rai...
