Состав и эффективность технологических комплексов для ресурсосберегающего земледелия = Composition and efficiency of technological sets for sustainable agriculture

Abstract

According the analysis of agricultural technologies and technical means development, technique sets suitable for Lithuanian conditions, for sustainable agriculture implementation were composed. Investment and energetic efficiency evaluation of those sets was made.Therefore technical and technological rates of more than 600 soil tillage, fertilising, sowing and crop treatment units, by of medium climate zone were summarised.This target equipment was made by 43 companies in Western Europe. Sets for sustaineble agriculture were chose for traditional and non-ploughing tillage systems, for sandy loam and clay loam soils, for 80-120 HP and 130-180 HP tractors. The comparison, made by medium material, supposed price, total energy inputs, showed differences of analysed technical sets efficiency. Especially they are significaint while comparing the sets for light and heavy soil (rates differs 3.0-3.5 times), traditional and non-ploughing agricultural means (difference is up to 1.5-2.1 times). The results of the research substantiate the principles of the flexible completeness of agricultural technique sets, considering economics and ecological development perspective
