Different model proto-horizons (MPHs) were assembled by means of the co-utilization of LDMs, other mineral matrices, organic amendment, and mineral fertilizer for the growth of a pasture grass under controlled (pot) conditions. The evolution of nine different MPHs was monitored by means of an evaluation/comparison of several physical-chemical parameters (texture, pH, electrical conductivity, N, P, K, and cation-exchange capacity) and the stability-modification of organic matter (OM) quality in relation to plant development (dry matter production, agronomic efficiency, and plant cover).
Anthropic-accelerated erosion processes have led to an increase in reported loss of soil surface horizons worldwide. Lake-dredged materials (LDMs) have often been considered suitable for upland disposal. This study aimed to assess the potential beneficial use of LDMs in soil rebuilding strategies for Mediterranean soils affected by the loss of surface horizons with consequent erosion/entisolization processes.

Abstract
Anthropic-accelerated erosion processes have led to an increase in reported loss of soil surface horizons worldwide. Lake-dredged materials (LDMs) have often been considered suitable for upland disposal. This study aimed to assess the potential beneficial use of LDMs in soil rebuilding strategies for Mediterranean soils affected by the loss of surface horizons with consequent erosion/entisolization processes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
