Field experiment has been found in 1969 in Skriveri on sod podzol loam which is the most widespread soil of Latvia. The soil conditions of farm, production means (buildings, agricultural machinery, livestock etc.) determines the usefulness of highly specialized farm. In these circumstances the right choice of crops and crop rotation is the most significant for increase of yield and maintenance of phytosanitary conditions of crops and soil. The maintenance of soil fertility in conditions of high specializations of crop growing, in complex with research crop rotation, soil tillage, fertilization and plant protection is the essence of project. The right conclusions of soil fertility, especially the maintenance and increase of content of soil organic matter under the influence of crop rotation, the various repeatability of growing of differnt crops, system of fertilization, as well as economic effectiveness cannot be made on basis of short term experiment. Basing upon the results obtained from long field trial we could offer: - to elaborate crop rotation recommendations for farms with different specialization - to determine the maximum specific part of different crops - barley, wheat, rye, oats, clover - in crop structure, this to determine the trend of specialization of farm - to study the problems with effectiveness of herbicides and fungicidesIn the collection "1999. gada zinatniskas petniecibas darba parskats".

EU‐Russia cross‐border co‐operation in the twenty‐first century: Turning marginality into competitive advantage

International audienceThis paper aims to examine how Russian north‐western regions and municipalities use their marginal/border position as a resource to build a sustainable development strategy. Theoretically, this study is based on the marginality theory which states that border or remotely located subnational units are able to turn their marginality from disadvantage to a resource and transform themselves from depressed and provincial territories to attractive places hosting intense international flows of goods, services, capital, technologies and people. A number of venues for the EU‐Russia cross‐border cooperation are explored: the European Neighborhood Instrument, Northern Dimension partnerships, Euroregions and city‐twinning. The authors conclude that despite some problems with establishing a proper division of labor between above programs and project implementation cross‐border cooperation proved to be a valuable instrument not only for successful development of the marginal/border actors but also for establishing mutual trust and collaborative relations between Russia and neighboring EU countries
