Abstract:

The aim of this research is to find and to evaluate energy crops with respect to their compactibility. It resulted in an evaluation of mechanical properties of seven crop species and in findings concerning mechanical parameters that exert influence on the compacting process. The evaluated mechanical properties cover the briquette density and the force required to break the briquettes. Following energy crops were studied: Sorghum vulgare, Phalaroides arundinacea, Crambe abyssinica, Fectusa pragensia, Camelina sativa, Miscanthus sinensis, Carthamus tinctorius. Before compression these crops were

Abstract:

Energy crops are grown for energy purposes. Traditionally energy crops are corn and sugarcane which are grown for industrial scale ethanol, rapeseed for producing biodiesel, annual and perennial grasses, for example cane, miscanthus, cereal straw, as well as fast-growing tree crops for biomass production. The most interesting for the temperate climate zone of Europe are the fast-growing willow species. The interest in growing energy crops, which can be used as a renewable energy source, in European countries arose in the 1970s, which was related with rising prices for traditional energy source

Abstract:

The present experiment was carried out in the period 2006-2008. The aim of this study was to determine the effect of aqueous soil extracts from the soil of a spring wheat monoculture on seed germination energy and capacity, the length of the first leaf and of the longest radicle as well as the number of radicles. Moreover, the content of 0-dihydroxyphenols in the soil was compared in the last year of the study. The soil used to prepare the solutions came from a field experiment established on medium heavy mixed rendzina soil. Spring wheat, cv. Zebra, was grown using plough tillage and two cons

Abstract:

The possible co-digestion of energy crops and industrial confectionery by-products with cow manure was evaluated firstly, through long-term batch experiments and secondly, in a farm-scale digester. In batch assays, digestion with mesophilically digested cow manure as inoculum resulted in specific methane yields (m3 kg−1 VSadded waste) of 0.35 for grass hay (particle size &lt;1.0 cm); 0.26 for oats (0.5 cm) and 0.21 for clover (2.0 cm) harvested at vegetative stage and 0.14 (2.0 cm) for clover harvested at flowering stage. Specific methane yields (m3 kg−1 VSadded waste) for confectionery by

Abstract The increasing consumption of energy, as well as exhaustibility of fossil resources, initiate the necessity of finding renewable resources. Especially biofuels represent the important role in terms of renewable resources, development of which is often question under debate in many countries. By increasing of blending mandate in the European Union (EU), the SR after joining the EU forced to implement the changes in its action plan for renewable energy in transport and set benchmarks share of methyl ester of rapeseed oil in diesel fuel.

Abstract:

AbstractThe excessive use of mineral fertilizers affects soil quality, gives rise to environmental problems and consumes energy. In contrast, organic amendment may improve soil quality at the same time as providing nutrients to plant. The aim of the work was to study the effects on crop yield and soil microbial activity of the successive addition of mineral fertilizers and fresh pig slurry before each successive crop compared with one sole application of different pig slurry composts (solid fraction of a pig slurry (CSFPS) and fresh pig slurry plus wood shavings (1:1 v/v; CPS+WS) before planti

Abstract:

The conception of critical limit (CL) of a nutrient element distinguishes its deficiency from sufficiency, which could advise fertilizer application. A pot culture experiment was conducted during Rabi season (2019–2020) to study the CL of sulphur (S) in soil and plant. A total of 20 soil samples collected from intensive cropping areas of three agroecological zones (AEZs) of Bangladesh were used in the experiment. The 0.15% CaCl2 extractable S (expressed as available S) contents of the test soils ranged from 6.84 mg/kg to 38 mg/kg. Wheat (Triticum aestivum L.) cv. BARI gom 30 and mustard (Brass

Abstract:

Efficient land and water management require the accurate selection of suitable crops that are compatible with soil and crop water requirements (CWR) in a given area. In this study, twenty soil profiles are collected to represent the soils of the study area. Physical and chemical properties of soil, in addition to irrigation water quality, provided data are utilized by the Agriculture Land Evaluation System for Arid and semi-arid regions (ALES-Arid) to determine crop suitability. University of Idaho Ref-ET software is used to calculate CWR from weather data while the Surface Energy Balance Algo
