In this study, the distribution of the total (TOC) and humified (HA+FA) organic carbon (C) in a 16 years-old peach orchard was evaluated by comparing the row that is tilled and irrigated and the inter-row that is covered with perennial grass. The grass favoured the accumulation of TOC and humified C in the top layer (0-20 cm), indicating that the absence of tillage promoted the accumulation of humified compounds. In the deep layer (20-40 cm) the TOC content was higher in the row while the content of humic substances was similar. TG-DTA analysis pointed out structural variations related to the carbohydrates and aromatic compounds content in the humic fraction of the samples taken from both top and deep layers of the two soil management systems.

Abstract
In this study, the distribution of the total (TOC) and humified (HA+FA) organic carbon (C) in a 16 years-old peach orchard was evaluated by comparing the row that is tilled and irrigated and the inter-row that is covered with perennial grass. The grass favoured the accumulation of TOC and humified C in the top layer (0-20 cm), indicating that the absence of tillage promoted the accumulation of humified compounds. In the deep layer (20-40 cm) the TOC content was higher in the row while the content of humic substances was similar. TG-DTA analysis pointed out structural variations related to the carbohydrates and aromatic compounds content in the humic fraction of the samples taken from both top and deep layers of the two soil management systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
