Abstract

Abstract Camelina [Camelina sativa (L.) Crantz], a recently rediscovered oil crop is becoming of interest to both industry and farmers due to its relatively wide use. The amount of camelina seed production is / will be influenced both by the demand from the industry and by the suitable conditions that allow its profitable cultivation. A preliminary insight on optimal part of the used arable land in Slovakia suitable for growing this crop was based on available information on the environmental requirements of camelina and the system of land evaluation units of agricultural soils. These data have been acquired from database managed and continuously updated by National Agriculture and Food Centre – Soil Science and Conservation Research Institute Bratislava. From this database information concerning the climatic region, slope, soil texture, soil depth, and skeleton content were used. The obtained results show that approximately 27% of the acreage of utilised arable land has optimal quality for spring camelina cultivation in Slovakia. If camelina will be used for the production of various biobased materials, on a smaller scale (several thousand hectares) it is possible to grow this crop without a significant restriction of the cultivation of other crops, especially those intended for food and feed production. In case of camelina utilisation as a feedstock for conventional biofuels production, it is necessary to take into account its competitiveness compared to oilseed rape, which is currently the main raw material for FAME (fatty acid methyl ester) production, both in terms of profitability of cultivation and CO2 emissions per tonne of oilseed yield.

斯洛伐克春季亚麻荠栽培的最佳适宜条件——土壤气候单元系统筛选
亚麻荠[Camelina sativa (L.)]Crantz],一种最近重新发现的油料作物,由于其相对广泛的用途,正引起工业和农民的兴趣。亚麻荠种子产量受到/将受到工业需求和适宜的有利栽培条件的影响。根据关于亚麻荠的环境要求和农业土壤土地评价单位制度的现有资料,初步了解了斯洛伐克适合种植这种作物的已使用耕地的最佳部分。这些数据是从国家农业和粮食中心-布拉迪斯拉发土壤科学与保持研究所管理和不断更新的数据库中获得的。从这个数据库中,我们使用了气候区域、坡度、土壤质地、土壤深度和骨架含量等信息。所得结果表明,斯洛伐克约27%的已利用耕地具有春季亚麻荠种植的最佳质量。如果亚麻荠将用于生产各种生物基材料,在较小的规模(几千公顷)上种植这种作物是可能的,而不会对其他作物的种植产生重大限制,特别是那些用于食品和饲料生产的作物。在利用亚麻荠作为常规生物燃料生产的原料的情况下,有必要考虑其与油菜相比的竞争力,油菜目前是FAME(脂肪酸甲酯)生产的主要原料,无论是从种植的盈利能力还是从每吨油籽产量的二氧化碳排放量来看。
