A wireless sensor network for vineyard management in Sicily (Italy)

2013

Wine quality depends on many factors, such as the choice of variety, stock, training system, pruning as well as environmental parameters and cultivation techniques performed in the vineyard. Monitoring the micro-climate of grapevine allows to conveniently perform the most important cultivation techniques (soil management, pesticide treatments, green pruning, harvest) thus reducing the operating costs of the vineyard, and increasing the overall quality of the grapes. The aim of the present study is to monitor the micro-climate of grapevine in order to control spring period hazards, to reduce the operating costs of the vineyard and to increase the quality of grapes. For this purpose a Wireles…

SOIL FERTILITY, GREENHOUSE GAS EMISSIONS AND AGRONOMIC PERFORMANCE IN A VINEYARD WITH DIFFERENT SOIL MANAGEMENT IN A SEMIARID MEDITERRANEAN ENVIRONME…

2017

In the semiarid Mediterranean environment, vineyard soils are often characterised by intensive tillage and large supply of inorganic fertilizers. Those practices, coupled with the semiarid Mediterranean climate features (warm to hot, dry summers and mild, wet winters),speed up the mineralisation of soil organic matter (SOM) so that many lands have lost much fertility. To counteract SOM decline, the introduction of cover crops with or without nitrogen (N) fixing forage legumes, has become a management technique widely used. Indeed, cover crops besides increasing SOM and potentially mineralisable N, it can mitigate soil erosion in sloping vineyards. However, the competition risk for soil wate…

Modeling soil organic carbon stock after 10 years of cover crops in Mediterranean vineyards: improving ANN prediction by digital terrain analysis.

2018

Estimate changes in soil organic carbon (SOC) stock after Agro Environment Measures adoption are strategically for national and regional scale. Uncertainty in estimates also represents a very important parameter in terms of evaluation of the exact costs and agro environment payments to farmers. In this study we modeled the variation of SOC stock after 10-year cover crop adoption in a vine growing area of South-Eastern Sicily. A paired-site approach was chosen to study the difference in SOC stocks. A total 100 paired sites (i.e. two adjacent plots) were chosen and three soil samples (Ap soil horizons, circa 0-30 cm depth) were collected in each plot to obtain a mean value of organic carbon c…

L'incremento della sostenibilità ambientale attraverso una corretta gestione dell'irrigazione.

2014

Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristichemeteorologiche e pedologiche, uno studio capace di valutare la sostenibilità della gestione irrigua in tre ipotetiche parcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (TP). Sitratta di tre vigneti che rappresentano per caratteristiche morfologiche e gestionali l'intero sottobacino, ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione irrigua in termini di risparmio energetico, attraverso l'applicazione del modello di bilancio idrico FAO 56. Questo tipo di studio pone le basi per la redazione …

Long-term effects of metal-containing farmyard manure and sewage sludge on soil organic matter in a fluvisol

2005

Abstract Our aim was to establish the long-term effects of repeated applications after 20 y of organic amendments (farmyard manure at 10 t ha −1  y −1 , and urban sewage sludge at two different rates, 10 t ha −1  y −1 and 100 t ha −1 every 2 y) on the quality of a sandy and poorly buffered soil (Fluvisol, pH 6). Chemical characteristics and biodegradability of the labile organic matter, which is mainly derived from microbial biomass and biodegradation products of organic residues, were chosen as indicators for soil quality. The organic C content had reached a maximal value (30.6 g C kg −1 in the 100 t sludge-treated soil), i.e. about 2.5 times that in the control. Six years after the last a…

Modelling soil carbon fate under erosion process in vineyard

2017

Soil erosion processes in vineyards beyond water runoff and sediment transport have a strong effect on soil organic carbon loss (SOC) and redistribution along the slope. The variation of SOC across the landscape determines a difference in soil fertility and vine productivity. The aim of this research was to study erosion of a Mediterranean vineyard, develop an approach to estimate the SOC loss, correlate the vines vigor with sediment and carbon erosion. The study was carried out in a Sicilian (Italy) vineyard, planted in 2011. Along the slope, six pedons were studied by digging 6 pits up to 60cm depth. Soil was sampled in each pedon every 10cm and SOC was analyzed. Soil erosion, detachment …

Rethinking vineyard ground management to counter soil tillage erosion

2022

Tillage erosion is a relevant process of soil redistribution in sloping arable land, but little research has analysed the effect of shallow tillage on soil erosion in vineyards. The goal of this study was to quantify the soil tillage effect on soil translocation and erosion at the territorial level in a large vineyard area in Sicily. The soil loss and soil erosion tolerance limits were compared to identify the vineyards with a high risk of soil degradation. An alternative management scenario to traditional tillage was proposed to evaluate the effectiveness of the best management practices on soil conservation. The experimental trials were conducted in 14 vineyards with different slopes and …

Cover Crop Impact on Soil Organic Carbon, Nitrogen Dynamics and Microbial Diversity in a Mediterranean Semiarid Vineyard

2020

Cover crop (CC) management in vineyards increases sustainability by improving soil chemical and biological fertility, but knowledge on its effects in semiarid soils is lacking. This study evaluated the effect of leguminous CC management on soil organic carbon (SOC) sequestration, soil nitrate content and microbial diversity in a semiarid vineyard, in comparison to conventional tillage (CT). SOC and nitrate were monitored during vine-growing season
