Energy consumption of primary tillage operations in conventional and no-till farming systems – a review
This article reviews domestic and international literature on the energy consumption of primary tillage operations in four farming systems: conventional (plough-based) tillage, simplified tillage, strip-till and no-till farming. The energy inputs of individual agrotechnical operations were analysed, with particular emphasis on fuel consumption, cumulative energy, CO₂ emissions and the impact on the physical and biological properties of the soil. The results of the review indicate that switching from ploughing to no-till farming reduces fuel consumption by 60–80%, energy inputs by 55–75%, and greenhouse gas emissions by 65–80%. At the same time, no-till systems promote the accumulation of organic matter in the topsoil, improve the stability of soil aggregates and protect against erosion. The limitations of no-till farming under Polish conditions were also discussed, including the risk of seed embedding in heavy soils, problems with weed control, increased reliance on herbicides, and economic and psychological barriers. An economic analysis of cultivation costs in individual systems was carried out for a model farm with an area of 100 ha.
