< p >我不知道很多关于斯堪的纳维亚半岛在1500年代,特别是森林是多少。然而,可以说整个地区之前冻结成冰的,与大部分的表层土壤被侵蚀掉冰,所以土壤通常是薄,不成熟,桑迪和营养不良。我们知道松柏成为主流,留下soil-litter松针。后一种阳离子交换容量高,导致酸冲每当下雨经过长时间的干旱时期。这种酸性浸出营养和增加小浓度的有毒金属。这些条件不帮助土壤的肥力。此外,谷层经常泥炭积累,因此高有机碳和酸度。斯堪的那维亚的地质复杂,难以推广。冰缘沉积在瑞典和丹麦一些肥沃的地区,特别是在有石灰石中和酸性的倾向。所以相比,俄罗斯,北欧土壤和农业潜力是更多的变量。 As regards climate, coastal Norway is much warmer than either eastern Scandinavia and Russia on account of proximity to the Gulf Stream Drift. It also has higher rainfall, so the effective growing season is longer. Northern Scandinavia and Russia have close to 24 hours sunlight per day in high summer, so one wonders whether two growing seasons per year for some crops might be feasible? Are there any agronomists out there who can advise on this question?
