Comparison of soil pH measurement in a non tilled vineyard: conventional labora...
Marques da Silva, JR; Terrón, JM; Blanco, J; Pérez, F; Galea, F; Moral, FJ; Alexandre, C; Serrano, J; Silva, LLThis work pretends to compare the soil pH measured by the 3100 Veris sensor with the conventional soil sampling in a specific soil condition of a non tilled vineyard. Whereas high density data was obtained with the soil pH sensor, which were used to delineate a pH surface using a geostatistical algorithm, conventional laboratory values were divided in two sets, depending on their location in a 3 or a 12 years n...
Energia, ambiente, economia e olival no Alentejo. Estudo preliminar
Baptista, F; Murcho, D; Silva, LL; Silva, JR; Marques, C; Dias, A; Peça, JO; Sousa, APrevê-se que o consumo de energia na agricultura irá aumentar significativamente nos próximos anos com a intensificação dos sistemas de produção. As melhorias na eficiência energética dos sistemas de produção estão relacionadas com a redução do uso de energia para um determinado serviço ou nível de actividade, ou a um aumento de produtividade para a mesma energia consumida. Os sistemas de produção agrícola estã...
Agriculture and energy efficiency in portuguese agriculture and trade-offs with...
Baptista, F; Marques, C; Silva, LL; Murcho, D; Silva, JR; Peça, JOThis paper aims to present and discuss an economic and environmental analysis based on case studies for selected Portuguese agriculture production systems which show potentials and constraints of energy efficiency measures in agriculture with respect to the specific environment of Portugal. Results are the Portuguese part of one work package of AGREE (AGRiculture and Energy Efficiency) an European project. It i...
Less or more intensive crop arable systems of Alentejo region of Portugal: What...
Marques, C; Baptista, F; Silva, LL; Murcho, D; Rosado, M; Silva, JR; Peça, JOCompetitiveness of traditional arable crop system of Alentejo region of Portugal has been questioned for long. Discussion and research on the sustainability of the system has evolved on two contrasted alternative options for production technologies to traditional system. On the one hand reduced and no tillage systems aim to more extensive technical operations reducing costs and maintaining production, or even t...
Otoczenie zewnetrzne efektywnosci energetycznej w rolnictwie – studium przypadk...
Golaszewski, J; de Visser, C; Lutsyuk, C; Stolarski, M; Brodzinski, Z; Olba-Ziety, E; Myhan, R; Mikkola, H; Ahokas, J; Jokiniemi, T; Rajaniemi, MUntil recently energy efficiency in agriculture has received little attention. Nevertheless, energy consumption in agriculture is considerable, especially when indirect energy use is taken into account. AGREE has the objective of showing the potential of short term energy efficiency gains and the promise of a long term potential. Environmental effects of savings on direct and indirect energy use in agriculture ...
Dzialania energooszczedne w rolnictwie (Energy saving measures in agriculture)
Golaszewski, J; de Visser, C; Stolarski, M; Brodzinski, Z; Olba-Ziety, E; Myhan, R; Mikkola, H; Ahokas, J; Jokiniemi, T; Rajaniemi, M; Meyer-Aurich, AThe reduction of energy inputs in agricultural production is a process of practical implementation of a set of energy saving (ES) measures associated with a given type of production, farm infrastructure and managerial or organizational activities. In six national reports from Finland, Germany, Greece, the Netherlands, Poland and Portugal for 13 subsectors of agriculture, 481 ES measures in total were identified...

Meyer-Aurich, A; Jubaer, H; Scholz, L; Ziegler, T; Daalgard, T; Yli-Kojola, H; Esala, J; Mikkola, H; Rajaniemi, M; Jokiniemi, T; Ahokas, JThis text is the result of the collaboration of the partners of the AGREE work-package “Economic and environmental analysis”, which is based on case study analyses of the partners in seven countries of the EU. The case studies show economic and environmental trade-offs in the different regions in the EU, for which each partner is responsible. Nevertheless prior to the reporting of the case studies an intensive ...
The fractal dimension of agricultural parcels considering maize yield
Marques da Silva, JR; Silva, LL; Sousa, AMOBefore making any decisions, all farm managers would like to have some indication about the effectiveness of a particular investment, especially when investing in precision agriculture technologies. Usually, the best indicator should be associated with the yield geometric complexity and its spatial and temporal dynamics. The fractal dimension of corn yield in a given year was calculated for six studied parcels,...
