Coratina) grown in irrigated and rainfed conditions. The trial was carried out in a semi-arid Mediterranean environment of Southern Italy. The root length density at different depths and distances from the trunk was examined during winter rest, flowering, and pit hardening.

Composting means to recycle organic waste to make compost—a high agronomic value product—able to positively affect soil quality: A good occasion to switch definitively from a conventional agriculture to an organic one. Nevertheless, composting can have negative direct/indirect environmental impacts. The aim of this research was to assess the sustainability of a windrow composting system, able to treat agricultural green waste of different typology (“light” and “heavy” with dry matter below or above 10%, respectively). Environmental impacts, energy consumptions, and production costs of all composting stages were evaluated by Life Cycle Assessment. Results show that the production of 1 ton of compost caused CO2eq emissions ranging from 199 to 250 kg and required between 1500 and 2000 MJ of energy; costs ranged between 98 and 162 euro,...

Among OMW detoxification techniques, those focusing on oxidative degradation of phenolic compounds are relevant. The composting (bio-oxidation) process in particular, exploits exothermic oxidation reactions by microorganisms to transform the organic matrix of OMW into an amendment biologically stable and feasible to use in agriculture. This process consists of an active phase during which organic compounds are rapidly decomposed, and a curing phase characterized by a slow breakdown of the remaining materials with the formation of humic substances (HS) as by-products. In this study, bio-oxidation of OMW was performed using a pre-treated organic material derived from municipal solid waste (MSW). The obtained amendment (OMWF) was stable and in accordance with the legislative ...

Chev.) CF Liang et AR Ferguson var. deliciosa) are presented. Exposed fruit (> 40% full sunlight) exhibited calcium content twice that of shaded fruit (< 20% full sunlight). Trends of Ca accumulation are discussed in relation to various known physiological and morphological fruit traits. Xylem functionality, fruit transpiration, fruit hair viability and fruit hydraulic conductance show significant changes ...

In this paper we discuss the most appropriate practices to preserve soil fertility and improve the efficiency of water and mineral resources. Soil incorporation of green manure, pruned ...

The trial was conducted using two year-old ownrooted olive trees, cv." Coratina", grown in 18 l containers and subjected to different stress levels determined on the basis of predawn leaf water potential measurements. Osmotic potentials at saturation (pi 100) were-2.06 MPa in ...

Il numero totale di specie rinvenute nelle aree considerate è stato di 83, a testimonianza di una elevata diversità floristica presente nelle zone interessate da tali indagini.
