Abstract
State forests are analyzed periodically, once every 10 years. This includes an analysis of forest soils. The present paperdescribes and interprets the chemical properties of forest soils from Bacau County focusing on the period 1983-2015. As such, 823 soil profiles and 2435 pedogenetic horizons were analysed taking into consideration the soil type, pH, humus content, nitrogen content, base saturation degree and the total cation exchange capacity. The most widespread types of soils are: eutriccambisol, luvisol, preluvisoland dystriccambisol. The dystriccambisols from Bacau County are strongly acid soils, while eutriccambisols and preluvisols are moderately acid. All forest soils from this area have a high cationic exchange capacity and are very well (dystriccambisol, eutriccambisol,luvisol) or well supplied (preluvisol, rendzina) with nitrogen. Knowing the chemical properties of soils is important for the analysis of stand variability and for adopting silvicultural methods adequate for the management of long-lasting forests.
Highlights
Bacau County occupies 2.8% from Romania’s total surface, namely 662,052 ha
The main soil types are identified through control profiles placed in all parcels and main profiles from the representative areas
The humus from the soil was established through the humid oxidation method and titrimetric dosage by Walkley-Black-Gogoasa method
Summary
Bacau County occupies 2.8% from Romania’s total surface, namely 662,052 ha. The county’s relief is relatively distributed between mountains, hills and plains. The highest altitude is 1,664 m in Tarcaului Mountains, while the lowest one which is 100 m can be found on Siretului Valley (Figure 1). Arable fields occupy 48.5% of the county’s surface, followed by forests with39.8% [1].The most widespread soil at a national level is dystric cambisol, followed byluvisolandeutriccambisol (Figure 1) [2]. State forests cover a surface of174267 ha, being managed by Bacau Forest District through its 14 Forest Districts:Bacau, Caiuti, Ciobanus, Comanesti, Darmanesti, Fantanele, Livezi, Manastirea Casin, Moinesti, Oituz, Sascut, TarguOcna, Traian andZeletin [3]
