DINAMICA DEI NITRATI E MINERALIZZAZIONE DEL CARBONIO IN UN SUOLO A VIGNETO IN AMBIENTE SEMIARIDO
2013
La gestione agronomica del vigneto in ambiente semiarido è spesso caratterizzata sia dalle frequenti lavorazioni del suolo che dall’apporto di fertilizzanti inorganici, in particolare azotati. Tale gestione, congiuntamente alle caratteristiche pedo-climatiche tipiche dell’ambiente semiarido, causa spesso un depauperamento del contenuto in sostanza organica del suolo e, dall’altro lato, incrementa il rischio di dilavamento di nitrati dal suolo. Al fine di controbilanciare tali effetti indesiderati, sono state introdotte nella gestione del suolo a vigneto tecniche di agricoltura conservativa, quali l’introduzione delle cover crops e l’interramento, previa trinciatura, dei residui di potatura,…
Effect of cactus pear cultivation after Mediterranean maquis on soil carbon stock, δ13C spatial distribution and root turnover
2014
Abstract Mediterranean ecosystems are characterized by nearly complete replacement of natural vegetation by intensive croplands and orchards leading to strong soil degradation. Organic carbon is usually accumulated in soils under maquis leading to partial regeneration of fertility for future agricultural use. The aim of this work was to investigate the effect of land use change from maquis to agriculture on soil organic carbon (SOC) stock and its spatial distribution in a Mediterranean system. Three Mediterranean land use systems (seminatural vegetation, cactus pear crop and olive grove) were selected in Sicily and analysed for soil C stocks and their δ13C. Total SOC and δ13C were measured …
Effect of Standard Disk Plough on Soil Translocation in Sloping Sicilian Vineyards
2022
Tillage is the main force of soil redistribution in agricultural land use and has been seen as more critical than water erosion. This study aims to evaluate the effect of tillage with standard disk in vineyards. A representative study area with grapevines was selected, and 39 inter-rows were selected to test the effect of slope and forward speed. In each inter-row, a strip of soil was collected, and mixed with 2 kg of coloured sand used as a tracer, then replaced in the strip, and shallow soil tillage was performed by means of a standard disk plough. Three soil subsamples were collected along the slope every 0.30 m from the coloured strip and the sand tracer was separated from the soil and …
L’importanza della biodiversità floristica nel vigneto siciliano
2023
La scelta di sistemi colturali ecocompatibili implica il mantenimento di una flora equilibrata, espressione di un’ampia biodiversità sito-specifica. Focus sul progetto siciliano STRA.VI.NA. e in particolare sulla valutazione di applicare protocolli di gestione suolo con inerbimento con specie autoctone: si sta salvaguardando e testando una lista di leguminose isolane atte alla costituzione di cotici erbosi per vigneti resilienti.
Cover Crop and Pruning Residue Management to Reduce Nitrogen Mineral Fertilization in Mediterranean Vineyards
2021
This paper aimed to study the effect of temporary cover crop and vine pruning residue burial as alternative practices to conventional tillage on soil nitrate (NO3-N) availability and grapevine performance in the short term. The trial was carried out in a rain-fed vineyard (Vitis vinifera L., cv Grecanico dorato/140 Ruggeri) located in a traditional Mediterranean viticultural area (37°
Real cover crops contribution to soil organic carbon sequestration in sloping vineyard
2019
Abstract The research focused on the evaluation of the effect of soil erosion processes on SOC sequestration rate after 5 years of cover crop soil management in Mediterranean vineyards (Sicily, Italy). Two paired sites, one in a sloping area and another one in a contiguous flat area, were chosen. The vineyard soils of the two plots of each paired site were managed with conventional soil tillage (CT) and Vicia faba cover crop (CC) the preceding 5 years. SOC was measured in three points along the slope (top, middle and foot parts) and in the flat area. Results showed that in the slope area the highest SOC content was found in CC management, with an average value of 9.52 ± 0.34 g kg−1, whereas…
Soil erosion assessment on tillage and alternative soil managements in a Sicilian vineyard
2011
Mediterranean crops favour high erosion rates. Vineyards use to reach the highest soil and water losses due to the lack of vegetation cover. A topographical approach by means of the use of vineyards poles as fixed reference point as erosion markers allowed to quantify high and non-sustainable soil erosion rates on the Sicilian vineyards during 9 years. In order to develop strategies to control the soil losses, seven land management were selected and applied in a typical blanc wine grape vineyard located in southwestern Sicily. Comparable plots were managed traditionally using conventional tillage and alternatively using various cover crops: 1) Vicia faba; 2) Vicia faba and Vicia sativa; 3) …
Managing soil nitrate with cover crops and buffer strips in Sicilian vineyards
2013
When soil nitrate levels are low, plants suffer nitrogen (N) deficiency but when the levels are excessive, soil nitrates can pollute surface and subsurface waters. Strategies to reduce the nitrate pollution are necessary to reach a sustainable use of resources such as soil, water and plant. Buffer strips and cover crops can contribute to the management of soil nitrates, but little is known of their effectiveness in semiarid vineyards plantations. The research was carried out in the south coast of Sicily (Italy) to evaluate nitrate trends in a vineyard managed both conventionally and using two different cover crops (Triticum durum and Vicia sativa cover crop). A 10 m-wide buffer strip was se…
