Abstract

Abstract
Soil organic matter and its components are important factors in formation and stability of aggregates and subsequently soil structure. However data regarding organic matter distribution in soil aggregates is scarce, particularly in arid soils of Central Iran. The objective of this study was to investigate the distribution of organic carbon (OC), total nitrogen (TN), and carbohydrates in aggregates of different size classes (2–4, 1–2, 0.5–1, 0.25–0.5, 0.05–0.25 and
