Shifting Long-Term Tillage to Geotextile Mulching for Weed Control Improves Soil Quality and Yield of Orange Orchards

2023

Weed control in urban and peri-urban orange orchards is challenging due to operational and legislative restrictions. Tillage, besides from negatively affecting soil fertility and microorganisms, is demanding for humans. On the other hand, herbicides are advised against due to the possibility to reach waterbodies from the soil surface. Therefore, in urban and peri-urban areas, instead of tillage and herbicides, mulching with black plastic geotextile fabric is often used. This study aimed at assessing the impact of long-term soil mulching with black plastic geotextile fabric on soil fertility, microbial community and yield of an orange orchard in comparison to conventional tillage. To this ai…

SHORT-TERM RESPONSE OF SOIL MICROORGANISMS TO ESSENTIAL OILS WITH ALLELOPATHIC POTENTIAL EXTRACTED FROM MEDITERRANEAN PLANTS

2015

Essential oils (EOs) with allelopathic compounds have been used to reduce or avoid weed germination and growth. The aim of this study was to evaluate the potential phytotoxic effects of EOs extracted from different Mediterranean plants on soil microbial biomass and activity. EOs were extracted from leaves of Eucalyptus camaldulensis Dehnh (EUC); Eriocephalus africanus L. (ERI); Thymus capitatus (L.) Hoffmanns. & Link (TCP); Citrus reticulata Blanco var. ‘Clemenules’ (TAN) and Citrus limon (L.) Osbeck var. ‘Eureka’ (LEM). Each EO was supplied to pots containing 560 g of soil at three different doses (low, medium, high). After 15, 30, 90, 120 days the supply of EOs, soils were destructively a…

SOME CONSIDERATIONS ON THE RELATIONSHIP BETWEEN UNIVERSITY STRATEGIES AND FINANCIAL INDICATORS

2010

A very important role in establishment and foundation the activities of a university is strategies and policies developed by management authorities. Through this article we identify the relationship between the components of university strategy and financial indicators, taking into account that financial projections are those that can affirm or overturn the objectives. In this respect, the article is structured in such a way that could provide answer to questions like: What kind of university strategy must be adopted to insure academic success? What is the premises development strategy, as requirements for success in university management? What financial indicators can influence the compone…

Marine Invertebrates as Bioindicators of Heavy Metal Pollution

2015

The marine environment presents a range of anthropogenic contaminants. According to the World Health Organization, more than 100,000 chemicals are released into the global environment every year as a consequence of their production, use and disposal. The fate of a chemical substance depends on physical-chemical properties, in combination with the characteristics of the environment where it is released. Among the substances that accumulate in the sea, for anthropogenic activities, metals/metalloids have a leading position. Some of these have a biological role but their bioaccumulation is injurious. Chemical pollutants can cause effects on organisms, biodiversity and human health. Various eff…

Forecasting pollutant emission of the urban vehicular running fleet by means of synthetic indicators

2003

The simple method here presented, devoted to the evaluation of the environmental performances of transportation systems, is mainly referred to the pollutant emission factors released within the "COPERT III” approach. The method is here adopted for building up a synthetic indicator of the whole pollutant emissions from the transportation sector in a given urban area. The indicator can be utilised in the aim of comparing the environmental effects of different transportation policies: the introducing of modal changes in the transportation demand from private cars to public vehicles, for examples, could be suitably analysed. Apart the knowledge of the proper pollutant emission factors, the meth…

Measuring Socio-Economic Welfare and Sustainable Transport – Selected Dilemmas

2017

The aim of this paper is to present and elaborate relations between the understanding and main indicators of socio-economic welfare, including indicators of sustainable development, and the measurement methods of sustainable transport. The focus is on the role that transport basically plays for nearly all dimensions of living conditions and the quality of life. First, the defi nition of socio-economic welfare and different views on measuring welfare are presented. Then, the meaning of transport for improving socio-economic aspects of life, as well as the need for sustainable transport are underlined. In the last part of the article developed indicators of sustainable transport are discussed…

Longitudinal and cross-sectional associations of adherence to 24-hour movement guidelines with cardiometabolic risk

2022

This study aimed to examine 1) adherence to 24-hour movement guidelines over a 2-year follow-up in children aged 6-8 years and 2) association of this adherence with cardiometabolic risk factors. Physical activity and sleep were assessed by a monitor combining heart rate and accelerometry measurements. Screen time was reported by the parents. Body fat percentage, waist circumference, blood glucose, serum insulin, plasma lipids and blood pressure were assessed, and a cardiometabolic risk score was calculated using z-scores. Children were classified as meeting the guidelines if they had on average ≥60min/day of moderate-to-vigorous physical activity during the valid days; ≤120min/day of screen…
