Straw uses trade-off only after soil organic carbon steady-state
2018
Soil organic matter (SOM) is the key for a healthy soil and a relevant property to achieve the sustainability on soil management. However, soils are still net exporters of organic matter. One example is the use of wheat straw residue for industrial and energy applications, which has gained attention in the last years. The offfarm use of this abundant and low cost resource should follow sustainability criteria to avoid soil degradation and SOM losses. Straw residue incorporation is recognized as a recommended management practice to control erosion and mitigate CO2 emissions by increasing SOM. The goal of this work was: i) to evaluate the steady-state carbon (C) level in relation to C input a…
Agricultural feedstock for solid and liquid biofuel production in Ukraine: cluster analysis
2019
This study is focused on the cluster analysis of biofuel feedstock in Ukraine. In recent years, Ukraine has been facing energy issues. There was a drop in fossil fuel production. On other hand, there has been a rise in crop production. Therefore, one of Ukraine’s priorities is to develop energy application using agricultural feedstocks. The cluster analysis was used to distinguish regions by their feedstock potential. Feedstocks for solid biofuel, bioethanol, and biodiesel were investigated. Promising groups of regions for biofuel production were identified. The results can be used to create autonomous power supply systems based on agricultural by-products (straw and husk). The corn belt se…
Life and economies in neo-Anthropocene: fruitful relationships between research, profession and local cooperation
2017
L’avvicinamento tra luoghi di produzione agricola e città, sempre più frequentemente, contribuisce alla progettazione di azioni coesive per riconfigurare il ciclo virtuoso della cattura della CO2 e della produzione di valori aggiunti “urbani”: diritti irrinunciabili, valore della vita, creatività. Questa tesi, in riferimento alla spinta progettuale ad un neo-Antropocene creativo (cfr. Ronsivalle 2016 e Carta, 2017), si può sostenere negli approcci teorici e metodologici e nella prassi dell’agricoltura urbana nelle sue varie forme. Tuttavia, solo nella costruzione di un quadro economico sostenibile, diventa possibile sviluppare un quadro ecologico utile alla riqualificazione dei sistemi urba…
The circular economy for resilience of the agricultural landscape and promotion of the sustainable agriculture and food systems
2022
The agricultural landscape is a public good to be preserved for long-term socio-economic and environmental effects. The agricultural landscape is preserved by the carrying out of agricultural activities. Through a empirical survey we examined how some young farmers in the countryside adopt conservation and resilience strategies. A common feature of the case studies examined is the adoption of photovoltaic energy production necessary for the performance of business activities. The method applied is that of the opportunity cost. The results of the research show that young farmers after graduation have returned to agriculture as they have an advantage in terms of opportunity costs compared to …
On the use of multi-temporal series of COSMO-SkyMed data for LANDcover classification and surface parameter retrieval over agricultural sites
2011
The objective of this paper is to report on the activities carried out during the first year of the Italian project “Use of COSMO-SkyMed data for LANDcover classification and surface parameters retrieval over agricultural sites” (COSMOLAND), funded by the Italian Space Agency. The project intends to contribute to the COSMO-SkyMed mission objectives in the agriculture and hydrology application domains.
The Effect of Mechanocatalytic Pretreatment on the Structure and Depolymerization of Willow
2020
In this study, the effect of a mechanocatalytic pretreatment on the structure of willow and sugar release from pretreated willow was explored. In the mechanocatalytic approach, the pretreatment consists of solvent-free impregnation with sulfuric acid and a mechanical treatment with ball milling. Willow sawdust and pretreated samples were analyzed with field emission scanning electron microscope and X-ray diffraction. The products in the sugar solution were determined as the total reducing sugars with the 3,5-dinitrosalicylic acid method and monosaccharides with capillary electrophoresis. According to the results, milling increased the sugar production, depending on the sulfuric acid load. T…
The potential of γ-ray spectroscopy for soil proximal survey in clayey soils Le potentiel de la spectroscopie a rayons-γ lors de l’echantillonnage pe…
2013
La spettroscopia di raggi-γ misura la distribuzione e l’intensità della radiazione gamma emessa naturalmente dai suoli o dalle rocce. I radionuclidi più importanti nel suolo come fonte di raggi gamma sono: 40K, 232Th, 238U ed 137Cs, quest’ultimo di origine artificiale, principalmente legato all’esplosione di Chernobyl o ad inquinamenti radioattivi. La distribuzione e la quantità di questi radionuclidi è strettamente dipendente dalla mineralogia del parent material e dalla capacità di scambio cationico del suolo. Scopo di questo lavoro è quello di mostrare le potenzialità di un rilevamento prossimale con spettroscopia di raggi-γ in campi sperimentali con suoli argillosi della Sicilia occiden…
Konkurencyjność przestrzenna rolnictwa w krajach Unii Europejskiej
2017
Celem opracowania jest zbadanie relacji między poziomem konkurencyjności rolnictwa w poszczególnych krajach Unii Europejskiej a przeciętną wielkością produkcji rolnej z 1 ha użytków rolnych. Dodatkowo w pracy podjęto próbę określenia charakteru przestrzennych zmian wielkości produkcji rolnej w podziale na sektory. Wyniki opracowano na podstawie metody zmian konkurencyjności Estebana-Marquillasa, która pozwala na diagnostykę potencjału produkcyjnego rolnictwa regionu. W szczególności analiza ta pozwoliła na wskazanie regionów wyspecjalizowanych oraz charakteru zmian strukturalnych w zakresie badanego zjawiska. Badania przeprowadzono na podstawie danych dotyczących wielkości produkcji rolnej,…

2017
W artykule skoncentrowano się na wskazaniu rosnącego znaczenia jakości infrastruktury transportowej w transporcie produktów rolnych i rolno-spożywczych. Dokonano analizy istniejącego stanu sieci dróg o twardej nawierzchni w poszczególnych województwach. Stosując taksonomiczne metody porządkowania liniowego sporządzono ranking województw ze względu na poziom rozwoju i jakość infrastruktury transportowej, do oceny której wybrano cztery cechy. Badaniem objęto lata 2010–2015, wyniki badań opracowano na podstawie danych GUS.
