Biogēno elementu saturs priežu un egļu jaunaudžu skujās pēc atšķirīgas intensitātes atjaunošanas cirtēm

2019

Mežizstrādes intensifikācija notiek ar mērķi tiekties uz ilgtspējīgu attīstību. Koksnes kā atjaunojamā energoresursa nozīme turpina pieaugt, tādēļ resursi jāizmanto maksimāli efektīvi. Vienlaikus nepieciešams optimizēt mežizstrādi atbilstoši vides vajadzībām. Visas virszemes biomasas aizvākšana un celmu izstrāde var būtiski samazināt augsnē pieejamo barības vielu daudzumu nākamajām koku paaudzēm. Darbā aplūkots kā atšķirīgas intensitātes kailcirtes ietekmē biogēno elementu saturu priežu un egļu jaunaudžu skujās. Darbā tika noskaidrots, ka virszemes biomasas aizvākšana apvienojumā ar celmu izstrādi veicina zemāku elementu saturu skujās, taču nenorāda uz kāda elementa trūkumu. Starp stumbru i…
