1990年3～8月,爱沙尼亚、拉脱维亚和立陶宛宣布从苏联独立。独立之后,波罗的海沿岸国家的农业从原来以庞大的集体农场为特征的国有经济,转变为以私有家庭农场为特征的市场经济。由于财政原因,无机肥的使用量下降到50年代的水平。1994年饲用牧草和饲料作物的产量仅分别为瑞典的40%和50%。由于出口的减少,波罗的海国家肉、奶、蛋总产量从1989年到1994年下降了40%～50%。本研究的目的是探讨独立以后波罗的海国家农业中氮、磷流动的变化,并与同期瑞典农业生产情况进行比较,特别是关于养分流动的变化,是否已经引起了养分从渡罗的海国家向波罗的海径流的变化。
From March to August 1990, Estonia, Latvia and Lithuania announced their independence from the Soviet Union. After independence, agriculture in the Baltic States turned from a state-owned economy that was once characterized by a large collective farm to a market economy characterized by private family farms. Due to financial reasons, the use of inorganic fertilizers dropped to the level of the 1950s. The yields of forage grass and forage crops in 1994 were only 40% and 50% of those in Sweden, respectively. Due to a decrease in exports, the total volume of meat, milk and egg production in Baltic countries dropped by 40% -50% from 1989 to 1994. The purpose of this study was to explore the changes in the flow of nitrogen and phosphorus in agriculture in the Baltic countries after independence and to compare with the Swedish agricultural production over the same period, especially with regard to changes in nutrient flows that have caused nutrients to migrate from the Borriqué to the Baltic Changes in runoff.
