Název v původním jazyce

Akumulacija ugljika i dušika u sastojini crne johe (Alnus glutinosa Gaertn.) u Podravini

Popis výsledku v původním jazyce

Istraživanja su provedena u 95-godišnjoj visokoproduktivnoj sastojini crne johe (Alnus glutinosa Gaertn.) u Podravini. Cilj ovoga rada je istražiti glavna obilježja akumulacije i dinamike ugljika i dušika u sastojini crne johe, kao indikatora stabilnostiekosustava i održivosti gospodarenja ovom sastojinom. Analiza dinamike i akumulacije ugljika i dušika tijekom godine obuhvatila je istraživanje tla, posebice šumske prostirke i A- horizonta, drva i kore crne johe te lista neposredno nakon odbacivanja. Masa šumske prostirke kreće se od 4,71 Mg ha--1 nakon odbacivanja lista, preko 3,36 Mg ha--1 u proljeće, do 0,51 Mg ha--1 u jesen prije ponovnog odbacivanja lista. Od jeseni do proljeća raste sadržaj ugljika i dušika u A- horizontu, a zatim ponovno opada.Akumulacija ugljika u nadzemnoj biomasi sastojine sredinom ljeta je 214,6 Mg ha--1, a u tlu je prosječno 143,5 Mg ha--1. S druge strane akumulacija dušika veća je u tlu -- u nadzemnoj biomasi je 2 Mg ha--1, a u tlu dosiže čak i preko 14

Carbon and nitrogen accumulation in common Alder forest (Alnus glutinosa Gaertn.) in plain of Drava river

Popis výsledku anglicky

This research was conducted in a 95-year-old, highly productive stand of black alder growing in the Drava plain in Croatia. The goal was to investigate the main features of carbon-nitrogen accumulation and dynamics in the stand of black alder (Alnus glutinosa (L.) Gaertn.), as an indicator of ecosystem stability and sustainability of managing such stands. Soil physiography was investigated in a permanent sample plot sized 1 ha with growing stock of 751 m3 ha--1. In the course of one season of leaf litter decomposition, the forest floor and soil from the A horizon were sampled on three occasions; the first sampling took place after leaf drop in 2009, the second at the beginning of vegetation (April 2010), and the third before leaf drop (beginning of November 2010). The forest floor mass was determined and so was the carbon and nitrogen content in the forest fl oor, in the bark, in the physiologically mature leaf and in the soil, as well as the soil pH value.
