Biochar and its applications have known a growing interest in these last years, due to its carbon sequestration capacity and its generally positive impact on soil and agricultural productivity. Next to the numerous studies assessing the positive effect of biochar on crop yield, little researches have been published elucidating the mechanisms responsible for the reported benefits of biochar on crop growth, production, and soil characteristics. Few studies cited soil moisture as the key factor attributing the increased yield to the higher soil water availability. Aim of this study was to investigate the effect of a biochar, produced from horticulture waste by pyrolysis, on the physical properties of an Italian agricultural soil. Three rates of biochar (10, 30 and 60 t/ha) were investigated. The soil used in the trial was loam with a long history of cropping. The trial was set on bare soil, to understand the direct effect of biochar on its characteristics.

Abstract
Biochar and its applications have known a growing interest in these last years, due to its carbon sequestration capacity and its generally positive impact on soil and agricultural productivity. Next to the numerous studies assessing the positive effect of biochar on crop yield, little researches have been published elucidating the mechanisms responsible for the reported benefits of biochar on crop growth, production, and soil characteristics. Few studies cited soil moisture as the key factor attributing the increased yield to the higher soil water availability. Aim of this study was to investigate the effect of a biochar, produced from horticulture waste by pyrolysis, on the physical properties of an Italian agricultural soil. Three rates of biochar (10, 30 and 60 t/ha) were investigated. The soil used in the trial was loam with a long history of cropping. The trial was set on bare soil, to understand the direct effect of biochar on its characteristics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
