The production of biogas from six agricultural crops was analysed regarding energy efficiency and greenhouse gas (GHG) performance for vehicle fuel from a field-to-tank perspective, with focus on critical parameters and on calculation methods. The energy efficiency varied from 35% to 44%, expressed as primary energy input per energy unit vehicle gas produced. The GHG reduction varied from 70% t...

In the framework of Geoland, Infoterra France has mapped with MERIS the distribution of annual crops surfaces in Belgium, Poland and Russia (Rostov oblast). The maps provided are the acreages of main groups of crops per administrative or agricultural circumscriptions unit. The groups are winter, spring and root crops (sugar beet, potatoes). The method for mapping exploits the MERIS capability t...

Climate is one of the most important factors that influence the quality and quantity of crops. Understanding the natural features of any region, especially about the climate, can play a major role in making plans and land use planning. Sugar beet, is one of the major industrial plants, that in addition to producing one of the most fundamental basic needs of society, namely sugar, it can have ot...

The decision of whether to release transgenic crops in the EU is one subject to flexibility, uncertainty and irreversibility. We analyse the case of herbicide-tolerant sugar beet and estimate the maximum irreversible environmental cost that can be tolerated for this technology from a benefit–cost perspective. Among Member States, these costs range from an annual € 50 to € 212 per hectare plante...

The ethanol fermentation process using beet molasses as the feedstock has been studied. The fermentation process, which was coupled with a membrane separation unit (Pervaporation), was compared to a conventional batch process. Ethanol was produced by Saccharomyces cerevisiae ATCC 9763 and recovered by pervaporation system using a composite polydimethylsiloxane (PDMS) membrane with 10 μm thickne...

sugar beet is one of the main crops in iranthat provides primary materials for sugar industries and so, its economic aspects are very important. one of these aspects is employment; it has begged to draw policy maker attentions. nevertheless, there hasnot been any survey study on this matter in iranyet. in this study, the current value of labor use in sugar beet cultivation (direct employment) i...

The EU sugar industry has a long tradition of maximising the use of co-products arising from the beet processing operation, all of which are used in productive applications. In fact, sugar factories are not only suppliers of sugar, but also produce other products, such as animal feed. All parts of the beet are used and converted into valuable products, without waste. These products are for the ...

in this research, the effect of crops such as corn, wheat, sugar beet and clover as previous crop on incidence of leaf and crown wart disease of sugar beet was studied. in the first year, corn, wheat, clover and sugar beet were planted as previous crop in a randomized complete block design with four replications. the amounts of turnover of nitrogen to the soil due to crop residue and their effe...

UAVs are becoming an important tool for field monitoring and precision farming. A prerequisite for observing and analyzing fields is the ability to identify crops and weeds from image data. In this paper, we address the problem of detecting the sugar beet plants and weeds in the field based solely on image data. We propose a system that combines vegetation detection and deep learning to obtain ...

This paper analyses the economics of biofuel production and the implications that the accelerating growth in biofuel production in many countries could have on agricultural markets. It shows that production costs of ethanol and biodiesel differ significantly across countries and feedstock crops. These costs often exceed those of fossil fuels. In consequence, the economics of biofuel production ...
